Taipinghua is a deciduous cluster shrub with height of 1-2 meters, flowering period from May to June and fruit maturity period from August to September. It likes sunshine and has strong resistance to shade and cold. It can survive in the open in North China, northeast, Southeast and northwest.
It can tolerate moderate drought and water, and can grow normally in 0.12% saline soil, but it is most suitable to grow in humid sandy loam. Long service life.
From August to September, the fruit is mature and the seeds are small. The pure seeds can be obtained after the retrieved fruit is put in a container for drying, kneading and removing impurities. For a winter of dry storage, mix the fine sand before and after the next year's Qingming Festival, and carry out pot sowing. Choose a higher and deeper pot, or sow in the courtyard. After sowing, a layer of film on the back cover is used for moisturizing, and a small amount of water can be drenched before emergence.
Most of them are carried out before sprouting in spring. The shoots from the mother plant can be divided with part of the root system and planted separately. In autumn, it is necessary to dig roots and seedlings, and to bury them for artificial planting. In the next spring, they can be planted.
Softwood cutting from late May to early June is conducive to rooting. The middle and upper parts of the current year's branches are selected, 10 cm long, with two or three upper leaves left.
The rooting powder can be used in conditional cutting, which can greatly improve the rooting rate. The rooting powder was soaked for 3 hours before cutting, and then cut into the soil. The temperature was controlled at about 25 ℃, and the rooting could take place in about 20 days.
In the growth period of each year, apply proper amount of compost, organic fertilizer or compound fertilizer once before germination in spring, and apply more phosphorus fertilizer after defoliation in autumn, which can make flowers flourish and leaves flourish.
During the growth period of summer, no fertilizer will be applied. In the dry season, pay attention to watering and keep the soil moist. If it is too dry or barren, it will lead to poor growth and less flowering.
In winter and spring dormancy period, the old branches, withered branches and over dense branches are thinly cut, and at the same time, the new techniques are promoted to make the crown beautiful and tidy. At the base of the branch, two or three buds were kept short, which made the old branch renew continuously.
If no seed is left after flower withering, the inflorescence should be cut off in time to save nutrients. In daily pruning, the diseased branches, dead branches and extra long branches should be cut off in time, and new branches should be kept to facilitate flowering.
The diseases and insect pests of taipinghua mainly include the moth, whitefly and so on. Once it is found that insecticides are sprayed in time, 2.5% deltamethrin 3000-3500 times liquid and 2.5% Kung Fu emulsion 4000 times liquid can be used for spraying, two or three times in a row, four or five days apart each time.
