Complete knowledge of flower cultivation in summer

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

Because of the high temperature and strong light, the water transpiration of plants 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 of flower cultivation, and flowers that are afraid of high temperature and heat, such as crab claw orchid, Daphne odora and Begonia, are often dormant or semi-dormant in summer. For these flowers, we should control and reduce excessive watering and stop fertilization, just keep the pot soil moist. Avoid too wet pot soil, otherwise it will easily lead to root rot and plant death.

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

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.

We should continue to fertilize pomegranate, hibiscus, Milan, jasmine and other blooming flowers. Plum blossom, peach blossom, winter jasmine and other flowers are in the stage of flower bud differentiation, so we should increase the application of phosphorus and potassium fertilizer and control the amount of watering to promote flower bud differentiation and make flowers bloom vigorously 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. When the weather is dry, the flowers and leaves of many Alpinia plants will roll up, resulting in burnt leaves, yellow leaves and poor growth. More attention should be paid to strengthening foliar spraying.

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

Plum blossoms are watered after the liquid is wilted and drooping, and the watering amount is about 60% to 70% of the usual watering amount. In rainy days, first put the side of the flowerpot well to keep the soil relatively dry.

Chrysanthemum and safflower are cored once every 20 days to control plant height and increase the number of branches, so that they 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% tetracycline 800 ~ 1000 times, or spraying 40% omethoate emulsion or 50% trisulfuric acid 2000 times. When there is a military pest, it can be killed by spraying omethoate.

Knowledge of July maintenance, matters needing attention in summer flower cultivation, how to cultivate flowers in hot days in summer and matters needing attention in summer family flower cultivation.

1. Planting

In July, the main woody ornamental plants that can be planted are plum, peach, peach, plum, apricot and plum. After harvesting the ripe fruits, wash the pulp and immediately furrow and sow, or store the cleaned seeds in wet sand and sow them in the ground after cracks. 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. In July, the suitable flower varieties are: Guayeju, Sijiaochun, kale, hyacinthus orientalis, freesia and so on. When planting grass flowers, special attention should be paid to moisturizing, ventilation and shading.

Step 2 cut

Woody ornamental plants suitable for cutting propagation in July include: Cinnamomum cassia, Nandina domestica, cherry blossoms, bergamot, poinsettia, Rosa roxburghii, Hypericum perforatum, Chimonanthus praecox, Berberis amurensis, Ligustrum lucidum in Phnom Penh, Ficus, hydrangea, brocade, HEMEROCALLIS HEMEROCALLIS, Gardenia, Xiang Jie, clove, fairy flower and hydrangea. Rubber tree, Qionghua, snowball, oleander, boxwood, fig, Magnolia grandiflora, Magnolia grandiflora, Osmanthus fragrans, Camellia, Camellia sinensis, Radix Aucklandiae, deciduous wood, Dendrobium loddigesii, Rhododendron, Rose, upside-down Admiralty, Golden Seed, Yingchun, 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, multicolored 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, seedlings such as peaches, plums and apricots planted in the spring of that year can be used as rootstocks to breed peaches, plums, plums and plums. Through "T-shaped" bud grafting, in order to peel off buds during bud grafting, potted soil or seedbed can be thoroughly watered two to three days before grafting, and dried slightly for 65438+.

Two-year-old potted seedlings of Chimonanthus praecox were used as rootstocks to graft fine varieties of Chimonanthus praecox. Taking Vitex negundo, Pingyi sweet tea and Pingyi sweet tea seedlings as rootstocks, the excellent varieties of Pingyi sweet tea and Pingyi sweet tea 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, Radix Aucklandiae, Oleander, Gardenia, Osmanthus fragrans, Magnolia grandiflora, Jasmine, Eupatorium fortunei, Hibiscus hibiscus, Spring Festival, Jasmine, Vine Rose and so on.

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 Rosea, Pineapple, Shierjuan, Chlorophytum, Ophiopogon japonicus, Anoectochilus roxburghii, Iris, Belamcanda, Gao Feng, Guangdong Evergreen and so on.

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