Complete knowledge of flower cultivation in summer

The rainy season is over and the climate is hot, which is a period of high temperature all year round. Therefore, there is a saying that there is no place to drill when it is hot, and there are often persistent high temperature weather and summer drought, with long sunshine time and high intensity.

Because of the high temperature and strong light, the transpiration of plant water increases, and the basin soil is easy to dry. It is necessary to replenish enough water in time to ensure the normal growth and development of plants. If the soil in the basin is too dry, the leaves will wither and turn yellow, the scorched edges and leaves will become smaller and fall off, and the growth potential will weaken or even die. In particular, flower varieties with huge leaves and poor keratinization are more sensitive to water, so attention should be paid to timely hydration.

There is little knowledge about flower cultivation, and flowers that are afraid of high temperature and heat, such as crab claw orchid, Daphne odora and Begonia, are often in a dormant or semi-dormant state in summer. For these flowers, it is necessary to control and reduce excessive watering, stop fertilization and keep the pot soil moist. Avoid too wet pot soil, otherwise it will easily cause root rot and lead to plant death.

Family knowledge of flower cultivation, indoor knowledge of flower cultivation and potted knowledge of flower cultivation.

Clivia, Rhododendron, Pinus pentaphylla and other flowers are afraid of high temperature weather and are in a semi-dormant state in summer. Although water supply should be normal, fertilization should be stopped.

Pomegranate, hibiscus, Milan, jasmine and other flowers with a large number of flowers should continue to be fertilized. Plum blossom, peach blossom, winter jasmine and other flowers are in the stage of flower bud differentiation, so we should increase the application amount of phosphorus and potassium fertilizer and control the watering amount to promote flower bud differentiation and make flowers flourish in the next spring.

According to the knowledge of flower cultivation, most foliage plants like humid environment and will not grow well at high temperature above 30℃. Water should be sprayed on the leaves and the surrounding environment 2 ~ 3 times a day to increase the air humidity and reduce the temperature. Many flowers and leaves of Alpinia officinarum will roll up when the weather is dry, resulting in brown leaves and poor growth. More attention should be paid to strengthening foliar spraying.

Because of the hot weather, potted flowers and trees decorated indoors should be placed outdoors at night to be nourished by dew and get some sunshine in the morning.

Plum blossoms should not be watered until the liquid is wilted and drooping, and the amount of water is about 60% to 70% of the usual watering. In rainy days, first put the side of the flowerpot well to keep the soil relatively dry.

Dense chrysanthemum and safflower every 20 days, control plant height, increase the number of branches, and make them have good plant shape.

When the weather is hot, muggy and dry, red spiders and military pests (pear net stinkbug) multiply rapidly and cause serious harm. When the red spider is harmed, it can be killed by spraying 40% dicofol or 20% mirex 800 ~ 1000 times, or spraying 40% omethoate emulsion or 50% trisulfuric acid 2000 times. When there is a military pest, omethoate can be sprayed to kill it.

Maintenance knowledge in July, matters needing attention in summer flower cultivation, how to cultivate flowers in high temperature days in summer, and matters needing attention in family flower cultivation in summer.

1. Planting

The woody ornamental plants that can be planted in July mainly include plum, peach, peach, plum, apricot and plum. After the ripe fruit is harvested, wash the pulp and sow it immediately, or store the washed seed core in wet sand, crack it and sow it underground. Canary dates can be bagged after germination in July. The seeds of Chimonanthus praecox can be sown with the harvest or hidden until next spring. The suitable species of flowers in July are: Guayeju, Sijiaochun, kale, hyacinthus orientalis, freesia, etc. When planting grass flowers, special attention should be paid to moisturizing, ventilation and shading.

Step 2 cut

Woody ornamental plants suitable for cuttage propagation in July include: Cinnamomum cassia, Nandina domestica, cherry blossoms, bergamot, poinsettia, Rosa davurica, Hypericum perforatum, Chimonanthus praecox, Berberis amurensis, Ligustrum lucidum in Phnom Penh, Ficus, Hydrangea, Hemerocallis, Gardenia, Xiang Jie, Lilac, Andromeda and Hydrangea. Rubber tree, Qionghua, snowball, oleander, boxwood, fig, Magnolia grandiflora, Magnolia grandiflora, osmanthus fragrans, camellia, tea plum, radix aucklandiae, deciduous tree, dragon spit bead, rhododendron, rose, upside-down golden bell, golden seed, spring jasmine, purple plum, bamboo banana, golden peach leaf coral, etc.

The species of grass flowers that can be propagated by cutting in July are: safflower, marigold, malachite, sunflower, carnation, begonia, colored grass, cold spray, amaranth, Dutch chrysanthemum, geranium, umbrella grass, coral flower, golden popcorn, nettle grass, hanging bamboo plum, pepper grass, silver grass, Guangdong evergreen and so on.

graft

In July, peaches, plums and apricots planted in the spring of that year were used as rootstocks to breed peaches, plums, plums and plums. Through "T-shaped" bud grafting, in order to peel off buds during bud grafting, the pot soil or seedbed can be thoroughly watered two to three days before grafting, and slightly dried 65438+.

Using potted 2-year-old seedlings of Chimonanthus praecox as rootstock, excellent varieties of Chimonanthus praecox were grafted. Taking Vitex negundo, Pingyi sweet tea and Hubei begonia seedlings as rootstocks, the excellent varieties of Pingyi sweet tea and Hubei begonia were cultivated by T-shaped bud grafting. Acer truncatum seedlings were used as rootstocks and bagged shoots were grafted with red maple and feather maple. Mao Juan's "Purple Butterfly" and "Jade Butterfly" were used as rootstocks to graft Rhododendron occidentalis or abdominal grafting.

Step 4: Stratification

The varieties of flowers and trees that can be propagated by layering in July are: Magnolia grandiflora (high pressure), Chimonanthus praecox, Lonicera japonica, hydrangea, Brocade, Qionghua, Snowball, Lingxiao, Aucklandia, oleander, Gardenia, Osmanthus fragrans, Magnolia grandiflora, Jasmine, Eupatorium odoratum, Hibiscus mutabilis, Yingchun, Jasmine and Vines.

5. Clonal ramets

In July, most of the plants that can be propagated by ramets are herbaceous flowers, such as Hosta Hosta, Purple Calyx, Polygonatum odoratum, Acorus calamus, Umbrella, Reineckea carnea, Eupatorium odoratum, Pterocarya pterocarpa, Pineapple, Shierjuan, Chlorophytum, Ophiopogon japonicus, Anoectochilus roxburghii, Iris, Belamcanda, Phyllanthus altissima, and Guangdong Evergreen.

Through our introduction, I believe everyone has a deeper understanding of the knowledge of summer flower cultivation.
