Handan Cherry Blossom Wholesale

Cherry blossom is a temperate and subtropical tree species. It likes sunshine and warm and humid climate, and has certain cold resistance. The requirement for soil is not strict, and it is suitable to grow in loose and fertile sandy loam with good drainage, but it is not resistant to saline alkali soil. The root system is shallow and waterlogged low-lying land is forbidden. It has certain cold and drought resistance, but has weak resistance to smoke and wind, so it is not suitable to plant in coastal areas with typhoon. There are more than 100 species of Sakura, which are distributed in temperate regions of the Northern Hemisphere: Asia, Europe and North America. The main species are distributed in western and southwestern China, Japan and Korea. Beijing, Xi'an, Qingdao, Nanjing, Nanchang and other cities in China have garden cultivation.

Mainly sowing, cutting and grafting breeding. Cherry blossom shall be cultivated by sowing. The seed embryo shall not be dried. It shall be sown as soon as it is picked or sown in the spring of the next year after the wet sand layer is accumulated. The seedlings of cherry and mountain cherry can be used as rootstock for grafting culture. Cut and graft in late March or bud graft in late August. After 3 to 4 years of cultivation after grafting, it can be planted out of the nursery. Sowing: Sowing the seeds of solid cherry blossoms after harvest, not suitable for drying. Because the seeds are dormant or stored in the sand in the spring of the next year, they are used to cultivate seedlings for grafting.
Before planting, the ground should be leveled, and a pit with a diameter of 0.8m wide by 0.6m deep can be dug. The pit should be filled with 10cm organic fertilizer first, and then the seedlings should be put into the pit, so that the roots of the seedlings extend around. After filling the soil, the cherry trees should be lifted up to expand their roots. The planting depth is about 5cm from the upper layer of the seedling root. After planting, water it, fully irrigate it, and use a stick to frame it to prevent it from falling down due to strong wind. During planting, 15 kg - 25 kg of compost shall be applied to each pit, and 1 kg - 2 kg of ammonium sulfate shall be applied to each plant in July. After flowering and before germination in early spring, it is necessary to cut off dead branches, diseased and weak branches and overgrown branches, and try to avoid pruning thick branches to keep the crown complete.
Fertilize cherry twice a year, preferably acid fertilizer. One is winter fertilizer. In winter or early spring, organic fertilizers such as bean cake, chicken manure and decomposed fertilizer are applied; Another time, after falling flowers, ammonium sulfate, ferrous sulfate, superphosphate and other fertilizers were applied. Generally, the big cherry trees can be fertilized by the method of hole application, that is, digging a circular ditch about 10 cm deep at the edge of the crown: positive projection line, and applying fertilizer. This method is simple and beneficial to root absorption. With the growth of trees, the diameter and depth of the circular ditch for fertilization will also increase. Cherry blossom has shallow root distribution, which requires good drainage and ventilation. Therefore, people, animals and vehicles should not tread on the soil around trees, especially within the root distribution range. Pedestrian trampling will weaken the tree, shorten its life, and even cause root rot and death.
Cherry should mainly prevent gummosis and rhizobia, as well as aphids, red spiders, scale insects and other pests. Gum flow disease is caused by moths drilling into tree trunks to lay eggs. You can use a sharp knife to dig out the eggs, improve the soil, and strengthen water and fertilizer management. Rhizobia will cause the roots of diseased trees to fail to grow normally. No matter how fertilizer is applied, the trees are still not strong. The tumor shall be removed in time, the soil shall be disinfected, and the soil shall be improved by sapropel soil, charcoal powder and microorganism.
Control method: strengthen cultivation management, prune reasonably, cut off diseased shoots, clean up diseased leaves and burn them in time to create clean growth conditions for plants. Before the sprouting of new shoots, 3-5 Baumedol sulfur mixture can be sprayed, and 160 times Bordeaux solution or 50% Benedet wettable powder 1000 to 2000 times solution, or 15% mancozeb 600 times solution to 800 times solution can be sprayed during the onset period. Leaf blight: yellow green round spots appear on the leaves in summer, and then become brown, with scattered black small particles. The diseased leaves wither but do not fall off.
