Why do leaves turn yellow when there is too much water at home? Usually change the water every 2 to 3 days.

Why do leaves turn yellow when there is too much water at home? Change the water every 2 to 3 days. 1. First, change the water every two to three days, and just change it once a month or two. It's best to put the water in the bottle and use it two days later. The bottle doesn't need to be covered.

2. Bamboo is placed in a place where the sun is not direct.

3, you can put nails to increase nutrition.

4, nutrient solution once every six months, just one or two drops.

The leaves of the rich bamboo at home turned yellow after changing water. Can vitamin c be used? The leaves of bamboo in water turn yellow mainly because it has no nutrition. Because it hasn't taken root yet, the nutrition can't be absorbed. You can cut off the yellow leaves and replace them with clean and clear water, which will take root after a while. However, the premise is that Fu Gui bamboo pole is hard or not.

Why is it strange to grow a rich tree with water red? How can the leaves turn yellow to save lives? The cultivation of rich trees

Fu Gui, also known as Sophora japonica, is a rare and excellent tree species with ornamental, greening, soil and water conservation and sand fixation in summer and autumn. It has developed rapidly since it was introduced to foreign countries for several years.

First, the biological characteristics of the rich tree

Fuguishu is a leguminous tree, Hua Die-shaped, with a height of10 ~12m, a straight trunk, sparse branches and grayish brown to brown bark. Leaves alternate, 17 ~ 19 pinnate compound leaves, oval to oval, smooth and bright green, larger than Robinia pseudoacacia leaves. It blooms from May to August, and it blooms continuously in Kechun and South China in summer and autumn. Axillary racemes droop, 8 ~ 12 cm long, with flowers near 10 cm. The conclusion of our local beekeepers is that "the flowers are large, abundant, beautiful in shape, long in flowering period, fragrant and rich in honey powder, which is a high-quality honey powder source for local beekeeping."

Rich trees not only like the excellent environment with abundant sunshine and good air circulation, but also can resist the cold of -25 ~ 28℃. In China, except Heilongjiang Province, they can grow well in neutral soil, acidic soil or light alkaline soil from coastal plain to mountainous area with an altitude of 2 100 meters. Its adaptability, easy propagation (both roots and branches can be propagated), fast growth (seedlings can be as high as 2 meters in the current year), reproducibility (many seedlings can be born in the second year after the roots are buried in the first year), high-quality honey powder source, ornamental, greening, sand fixation, soil and water conservation and other economic and ecological values determine its broad development prospects.

Second, the breeding technology of the rich tree

Rich trees have good flowers but no pods and no seeds for reproduction. They can only reproduce asexually by burying roots, cutting branches or grafting.

1. Buried roots for reproduction. This is the most important breeding method, and the survival rate is 85% ~ 90%.

(1) Seed preparation: The seed roots of the rich tree can be introduced after defoliation. Before planting, they should be buried in the sand and stored, and the humidity of the sand should be controlled so that the root segments are not dehydrated and dry, and the humidity should not be too high to avoid mildew and rot.

② Soil preparation: It is best to choose sandy loam with deep soil layer, flat terrain, convenient irrigation and drainage, and no infection source of pests and diseases. Apply 2500 kg of livestock manure per 667 square meters, or 50 kg of phosphate fertilizer and hydrazine as base fertilizer; Use carbofuran and other pesticides to kill underground pests. The ground should be deeply turned, trimmed and raked, and the width of the frame should be about 1 m.

③ Seedling raising: the seedling raising time is early March in the south and early April in the north. Select smooth root segments with a diameter of 5 ~ 10 mm 1 ~ 2 years old, and cut them into 5 ~ 7 cm long for later use. Trenching along the border with a spacing of 50 cm and a depth of 5 cm, then placing the root segments in the trench with a spacing of 30 cm, covering them with fine sand, pouring the root water thoroughly, and covering them with plastic film, and the seedlings can emerge in about one month.

(4) Seedling management: after emergence, uncover the film and water it in time, and pay attention to drainage when it rains. Weed in time at seedling stage, wipe off lateral buds, relax topsoil, and do not hurt tender, weak and short roots. Timely prevention and control of pests and diseases, proper fertilization, long-term drought, drought-resistant water fertilizer and topdressing, and promote the growth and health of seedlings.

⑤ Transplanting and management: The seedlings of Fuguishu should be transplanted and planted after defoliation in late autumn of that year or before germination in spring of the following year. Construction as planned, applying base fertilizer, filling soil after planting and pouring root water thoroughly, the survival rate is generally above 95%. After autumn, the height of the tree can reach 2 ~ 3 meters and DBH 3 ~ 5 cm. It bloomed the next year. The flowers were gorgeous, the fragrance was attractive, and the tree-shaped opening was beautiful and lovely.

2. Prune.

① The cutting time is the same as that of burying roots to raise seedlings, or it can be earlier.

(2) Select lignified hard branches with a diameter of 8-20 mm, cut them into cuttings with a length of 15cm, cut the upper incision flat, with a distance of 1 ~ 2cm from the bud bag, cut the lower incision into a 45-degree oblique mouth, with a distance of 5mm from the bud bag, divide the upper and lower ends into a bundle of 50, soak the lower end in 50 mg/kg rooting powder solution for 3-4 hours, and take it out for later use.

(3) The requirements for soil preparation are the same as before. According to the row spacing of 20 cm× 40 cm, the branches are inserted into the soil at a 45-degree inclination angle, and the plastic film is covered along the border.

(4) Seedling management: after the emergence of seedlings, drill holes in time, dig seedlings to seal the soil, keep the temperature and humidity of the bed soil, remove the plastic film before high temperature, erase the lateral buds, and strengthen the management of fertilizer and water. Cutting seedlings can grow to more than 2 meters in that year.

Fu Guishu has simple management and low production cost, and is suitable for large-scale construction such as beekeeping, garden viewing, windbreak and sand fixation, and soil and water conservation. And it works quickly.

This is the reason why plants turn yellow and fall leaves. Please refer to:

1. Long-term waterlogging of soil in the Yellow River Basin leads to soil hypoxia, which weakens the ability of some roots to rot and absorb water and fertilizer. It is characterized by dark yellow leaves, atrophy of the top of new shoots and small yellow-green branches. In this case, we should loosen the soil, control watering and stop fertilizing. In severe cases, we can take off the pot and put it in the shade to dry the soil balls and put them in the pot.

2. The yellow leaves caused by excessive fertilization or high concentration, especially the biased application of nitrogen fertilizer, show that the new leaves are thick and shiny, but the leaves are uneven and the old leaves gradually turn yellow and fall off. At this time, fertilization should be stopped, the amount of watering should be increased appropriately, and nutrients should be diluted. Potted flowers are short of fertilizer and water, or a big pot is small, and the roots in the pot are aging or too dense, which will also make the leaves of flowers and plants thin and yellow. At this time, it is necessary to change pots and soil, usually from rainy to long summer.

3. Alkaline yellow potted flowers, such as camellia, Milan, Michelia, Rhododendron and Jasmine. Due to the alkaline reaction of soil, they often lose their green and yellow colors. It is manifested in the veins starting from the new leaves at the branches, while the veins, especially the main veins, remain green and the yellow-green phenomenon is very obvious. With the aggravation of yellowing, the veins gradually turn green, then the whole leaves turn white, the leaves are scorched, the leaves wither, and in severe cases, the branches wither and the whole plant dies. For this "yellowing" phenomenon, acid fertilizers or acidic substances can be used to improve it, and alum fertilizer can also be used frequently.

4. Flowers as dark as sunlight often turn yellow due to insufficient indoor light. At this point, pots and pans should be moved to outdoor ventilation and lighting. For semi-negative flowers, such as asparagus, leaves will turn yellow under strong light, so to avoid exposure to high temperature and strong light in summer, they should be moved indoors or stored in a light-proof shed.

5, drought and yellowing Due to long-term non-watering, or less watering, the leaves turn yellow or brown ends and brown edges appear, and the old leaves fall off from bottom to top. However, new leaves generally grow normally, so when this happens, water should be added to make the soil no longer short of water.

6. Burning yellow likes wet potted flowers, such as chlorophytum, evergreen, Hosta, etc. If exposed to strong direct sunlight, leaves also have brown ends and brown edges. If this happens, put the jar in the shade.

7, hot and humid yellowing Some potted flowers that are not resistant to high temperature and high humidity, the leaves are yellow due to poor ventilation and improper shading in midsummer, such as hanging bell begonia, this phenomenon occurs in summer. Therefore, high temperature and high humidity can easily lead to yellowing of leaves, which can be prevented by paying attention to ventilation and cooling, and the soil in the basin should not be too wet.

How to hydroponically cultivate Fu Guizhu? Change fresh water every 3 to 4 days. 1 Water should not be changed after rooting in hydroponics, and water can only be replenished in time after water evaporation is reduced. Changing water frequently can easily cause yellow leaves to wither.

Don't put too much water in the hydroponic container, just immerse the lower part of the rhizome 5 cm. Too much water is easy to rot stems and not easy to take root.

? Better add well water. Tap water should be stored in a container for one day. Water should be kept clean and fresh. Dirty water, hard water and oil and water should not be used, otherwise the roots will rot easily.

Daily maintenance should be placed in a bright place, not exposed to the sun. If there is a little scattered light, it is also good. Pay attention to keep a warm environment, and the temperature should not be lower than 5 degrees. (Special reminder: Fu Guizhu does not grow well in alkaline soil and dry climate, and its tip is easy to dry up. Long-term indoor shelter from rain also grows thin and leaves are dim, so pay attention. )

Avoid the wind. Don't put bamboo near the TV or where air conditioners and electric fans often blow, so as not to dry the tips and edges of the leaves. When the weather is dry, properly spray water on the leaves to ensure that the leaves stretch green.

Is the yellowing of Fu Guizhu and Julia raised at home a problem of excessive formaldehyde? It is very likely that many people think that the bigger the leaves, the more they can absorb formaldehyde, but forget that plants can breathe! Hoo hoo! It is recommended to install a clean wind ridge fresh air system at home to prevent excessive formaldehyde in the home from causing physical discomfort!

Why are the leaves of my rich bamboo in Phnom Penh yellow? As long as the temperature is low and plants are not suitable for growth, just put them in a bright place indoors. If the temperature is high, trim the yellow leaves and often spray water on them.

My family is rich in bamboo, the roots are yellow in water, but the leaves are old and yellow. I change the water every ten days. Fuguizhu likes a warm, humid and sheltered environment. I prefer scattered light to direct sunlight. Should be loose and fertile soil.

The following essentials should be mastered in raising rich and precious bamboo in bottle water:

Remove the leaves from the base of the cuttings and put them into the bottle. Cut the base into oblique corners with a sharp knife. The blade should be smooth to increase the absorption area of water and nutrients. Change the clean water every 3-4 days, and put a few small pieces of charcoal in it to prevent corrosion. Don't move or change direction for 10 day, and silvery white fibrous roots will grow around 15 day.

After changing water, it is not advisable to change water and add water to take root, and water can only be added in time after water evaporates. Changing water frequently can easily lead to yellowing of leaves. Better add well water. Tap water should be stored in a container for one day. Water should be kept clean and fresh. Dirty water, hard water and oil and water should not be used, otherwise the roots will rot easily.

Fertilize and water in time to cultivate rich bamboo. In order to prevent excessive growth, don't apply chemical fertilizer. It is best to inject a few drops of brandy into the bottle every three weeks or so and add a small amount of nutrient solution. You can also use 500 grams of water to dissolve half an aspirin or a VC, and drop a few drops when adding water to keep the leaves green.

Avoid the wind. Don't put bamboo near the TV or where air conditioners and electric fans often blow, so as not to dry the tips and edges of the leaves.

There are several reasons why the rich bamboo will cause yellow leaves. Please refer to them:

First, the water is yellow. The yellow leaves caused by long-term watering show that the young leaves are yellow and dull, and the old leaves have no obvious changes. The roots are small yellow-green, and the new buds do not shrink. To control the water, you can take off the basin when it is serious, dry the soil in the shade and put it in the basin.

Second, drought and yellow. The leaves turn yellow because of lack of water or water. Old leaves wither and fall off from bottom to top, but new leaves generally grow normally. The amount and frequency of watering should be appropriately increased.

Third, fat yellow. Because of too much fertilization or too high concentration, the new leaf tip appears dry brown, and the old leaf tip also appears dry brown. The leaves are generally plump and shiny, but most of them are uneven. Should stop pouring fertilizer or rinse fertilizer with clear water.

Fourth, the lack of fat yellow. Potted flowers are only watered for a long time without fertilization, or the pots are not changed for many years. The roots must form a ball, and the plants can't get fertilizer, which makes the leaves yellow. In addition to changing pots in time, thin fertilizer should also be applied frequently. For example, rich bamboo often lacks iron and yellow leaves. Woody flowers in greenhouse often have yellow leaves because of the great changes in soil fertility conditions, which are characterized by obvious young leaves, light old leaves, yellow mesophyll and green veins, forming a typical network; This solution can be solved by applying ferrous sulfate aqueous solution. The method is as follows: 7 parts of cake fertilizer, 5 parts of ferrous sulfate and 200 parts of water are poured into various liquids.

Fifth, burn yellow. I like wet potted flowers and foliage plants, such as chlorophytum, evergreen, Eupatorium odoratum, Hosta, etc. If their leaves often have yellow tips after strong direct sunlight, they should be kept in the shade.

Sixth, alkali yellow. Flowers that like acidic soil, such as Rhododendron Camellia, Osmanthus fragrans and Cymbidium hybridum, often turn their leaves from green to yellow or even fall off, such as potted soil or alkaline water. In addition to using acidic nutrient soil for culture, alum is rich in water or 0. 2%-0。 Spraying 5% ferrous sulfate aqueous solution can not only change the leaves from yellow to green.

Seven, damp and hot yellow. Some flowers that are not resistant to high temperature and high humidity turn yellow due to hot summer, poor ventilation and improper shading. If the golden bell jar is upside down, the cuckoo has this phenomenon in a hot and humid environment. Attention should be paid to ventilation and cooling, and the pot soil should not be overheated.

Eight, albino yellow. Due to insufficient illumination in flowers, chlorophyll in leaves decreases, which makes the green of leaves gradually disappear, showing albinism. You can move the plants to a sunny place and let the leaves turn green slowly.

Nine, low temperature yellow. In cold winter, if the indoor temperature is low, some flowers that are afraid of cold, such as white orchid, Guangdong evergreen and poinsettia, will turn yellow and their leaves will fall off. In addition, flowers harmed by pests and diseases will also cause yellow leaves to fall off. It is normal if a few leaves turn yellow and fall off at the lower part of the plant.

Why do the leaves of Zizhumei grow yellow in water? Now the temperature of the leaves of Zizhu plum is lower, and the plants grow better and more vigorously. Every time you water it, you can add some nutrient solution, and the leaves are greener, brighter and bigger.

Why does the water hyacinth in the cement pool turn yellow? If the climate is suitable, throw it directly into the pond (preferably a fish pond, the water is rich enough, and the oxygen content in the water should be ensured at the same time, such as running water or artificial oxygenation), and grow by itself, and it grows very fast, basically without "natural enemies" (because the species is an alien species), and soon the pond is full.

There are many reasons why the leaves of Bambusa bambusa turn yellow. See what kind of reason you belong to, and you can prescribe the right medicine. The following are the reasons why the leaves of bamboo plants turn yellow and the treatment methods I provide for you: the scorching yellow strong sunlight directly shines on bamboo, which is easy to cause the tip and leaf edge of flowers to wither, and yellow spots appear in the sunrise part of the leaves. Move to the shade. Yellow leaves are shaded for a long time, so the leaves don't get enough sunlight to form chlorophyll, and the whole leaves turn yellow and then fall off. Supplementing light can avoid this disease. The yellowing of flowers caused by excessive fertilization or high concentration of fertilizer yellow shows that the top of new leaves is yellow, generally thick, dull, concave and convex, and the old leaves are brown and fall off. Fertilization should be stopped immediately, and some fertilizers should be washed carefully with a lot of cleaning. The lack of fertilizer yellow shows that the color of young leaves turns pale to yellow or light green, and the old leaves turn normal or gradually from green to yellow. Apply thin fertilizer frequently at ordinary times and replenish some alum water in time. (Phyllostachys pubescens is a foliage plant, so nitrogen fertilizer should be applied. )
