Scientific watering

1. Watering time

As the flower proverb goes, "If it's not dry, don't water it; if it's watered, it's watered thoroughly." How to judge whether potted flowers are dry? ① Look at

Growth

Some flowers and trees, such as impatiens, primulas, hydrangea and other plants and flowers with soft leaves, when you see them If the new shoots and leaves are soft and drooping, it indicates a lack of water. Once the water is replenished, they will stand up quickly. This method is very effective. ②Check the soil in the basin. Put your hand into the basin and use your fingers to scrape the topsoil. When your fingertips feel cold, it means there is water in it. When your fingers feel that the soil is hard and does not feel cool, it means It's dry inside. ③Knock on the wall of the basin

Tap the wall of the basin with your fingers or a small wooden stick. When you hear a dull and dull sound, it means there is enough water inside. When the sound is crisp and loud, it means that the inside is dry. ④Look at the weather

In summer and sunny days, water evaporation is large, so watering should be frequent. In winter and rainy days, water evaporation is slower, so watering should be less. Generally, water should be watered 1 to 2 times a day on sunny days in summer, and once every 1 to 2 weeks in winter. The temperature of the water should be the same as the temperature of the soil. It is best to do it in the morning and evening in summer, and at noon in winter. 2． Water quality

Rainwater and pond water are best for watering flowers. For ordinary flowers, tap water is also acceptable. However, for acid-loving flowers such as orchids and azaleas, it is not advisable to water them directly with tap water. You should first put the tap water in a tank or pool, and store it in the open air for a few days to allow the chlorine inside to completely evaporate before use, or add 0.0% to the water. . Use 1% ferrous sulfate after modification.

3． Amount of watering

The amount of watering depends on the size of the flower pot and the dryness and humidity of the pot soil. The principle is: water thoroughly. If the plant is not watered thoroughly for a long time, the soil in the pot will become wet at the top and dry at the bottom. The root system of the flower will not be able to extend downward well, which is detrimental to growth. If you water too much, a large amount of water will drain from the holes in the bottom of the pot, taking away the nutrients in the pot. The correct method of watering is to water 2 to 3 times in a row. Don't water too much the first time. After a while, wait until all the water in the pot is absorbed by the soil, then water some more until water slowly seeps into the hole at the bottom of the pot. Until it goes out.

4. A few tricks for watering flowers: Beer

Beer for watering flowers is an excellent aromatic fertilizer. When pulling out arrows, water the Clivia in small amounts several times to prevent the Clivia from catching arrows. Sugar water

Water flowers During the growing season of asparagus, watering sugar water solution once every 10 days or so can make asparagus grow vigorously, with luxuriant branches and shiny leaves. Rice water

Water flowers with rice water. Rice water is often used to water Milan and other flowers to make the flowers brightly colored and the branches and leaves luxuriant. Vinegar

Water flowers in the south and grow them in the north. They like acidic soil. If the pot soil is less acidic, the flowers and leaves will turn yellow and even die. At this time, watering the flowers with rice vinegar diluted with water will make the flowers and leaves turn green again. Boiled egg water

Water boiled egg water to water flowers. Boiled egg water is rich in minerals and can be used to water flowers after cooling, which can promote the normal growth of flowers. Cool boiled water

If used to water Asparagus asparagus, it can make the branches and leaves grow horizontally, grow dwarfed and densely. Watering other flowers can promote early flower buds. 5． Several points to pay attention to when watering

(1) Flowers will die if watered too much: If potted flowers are watered too much, water will fill the gaps in the soil, and the air in the soil will be replaced by water, causing a lack of water in the soil. Without oxygen, the root tissue will have difficulty breathing due to lack of oxygen, and its metabolic function will be reduced, resulting in obstruction of water and fertilizer absorption. In the long run, the flowers will suffocate and die.

(2) Disadvantages of insufficient watering of potted flowers: If the water supply is insufficient, the leaves and petioles will shrink and droop, and the flowers will wilt. If the flowers are in this condition of insufficient water supply and leaf wilting for a long time, the older and lower leaves of the plant will gradually turn yellow and dry up. If most flowers and plants are in a drought state for a long time, the plants will be short, the leaves will lose their bright green luster, and the entire plant will even die.

(3) Rescue of dehydrated potted flowers: Due to missed watering or hot weather, the pot soil is too dry, causing the twigs to droop and the leaves to wil. In this case, you cannot pour a lot of water immediately. You should first move the flowerpot to a semi-shady place, pour some water, and spray a small amount of water on the leaves. As the stems and leaves recover, gradually increase the amount of watering. . If you pour heavy water immediately, not only will the plant not be able to recover, but it may cause the leaves to turn yellow and fall off, or even the entire plant to die. Because when flowers are severely wilted, the root hairs are damaged and their water absorption capacity is reduced. Only when new root hairs are formed can the original water absorption capacity be restored. At the same time, wilting causes cells to lose water. When exposed to water, the cell wall absorbs water first, and the protoplasm absorbs water later. If too much water is applied at once, the cell wall will absorb water and expand rapidly, while the protoplasm absorbs water more slowly, resulting in plasmolysis and damage. protoplasm, causing plant death.

(4) To deal with the temporary water shortage of potted flowers: Place a water container slightly higher than the flower pot, use a highly absorbent cotton fabric (such as thick towel, cheesecloth, etc.), Place it in a container filled with water, and press the other end on the flower pot soil. In this way, due to the capillary action of the wet towel, the water in the container will slowly infiltrate the pot soil, thereby keeping the pot soil moist and achieving the purpose of regular watering.

(5) It is not advisable to water flowers with cold water at noon in hot summer: At noon in hot summer, the temperature is very high, and the temperature of flower leaves can often be as high as about 40°C. Transpiration is strong, and water evaporates quickly, and the root system needs constant watering. The ground absorbs a large amount of water to compensate for the loss of transpiration from the leaves.

If you pour cold water at this time, although the water in the pot soil has increased, due to the sudden and sharp drop in soil temperature, the root hairs will be stimulated by the low temperature, which will immediately hinder the normal absorption of water. However, at this time, the stomata on the leaf surface are not closed, and the amount of transpiration is very large. As a result, the balance of water supply and demand is lost, causing the leaf cells to change from a swollen state to wilting, causing the plant leaves to scorch, and in severe cases, the entire plant will die. This phenomenon is especially obvious in herbaceous flowers, such as geraniums, angustifolia, and aster. It is most taboo to pour cold water directly at noon in hot weather. Watering cold water at high temperature at noon during the early stages of budding, flowering, and fruit setting of flowers can also easily cause bud and flower drop. Fruit drop.

(6) It is advisable to use warm water when watering flowers in early spring: Watering flowers with warm water below 40°C in early spring can make the flowers have strong roots, lush leaves, and colorful flowers, and can promote early budding and blooming of various flowers. , this is because the average temperature of the upper leaves and stems of the flower plant is generally higher than the temperature of the roots. In addition, when the leaves and stems perform the three major functions of photosynthesis, respiration and evaporation, their cell activities are relatively fast. Therefore, the roots need to be supplied with sufficient water and nutrients in a timely manner. If the root temperature is too low at this time and the cell activity is slow, it will directly affect the rapid growth of the upper leaves and stems of the flower plant. If you often water flowers with warm water of 30~40℃, it can relatively increase the soil temperature, accelerate the decomposition of various organic matter in the soil, promote the absorption and division of flower roots, and fully supply the nutrient needs of the upper leaves and stems of the flower plants.
