The cultivation of winter jujube seedlings has been in Zhanhua for more than 1,000 years. According to the investigation of the winter jujube garden in the past hundred years, it is a winter jujube seedling grafted from a local jujube. At present, there is no large-scale stem-root seedlings. Grafting is used to breed winter jujube seedlings. In order to improve the breeding speed of winter jujube seedlings, advanced seedling raising methods such as shoot propagation, whole haze breeding, tissue culture and so on were used to breed the stem-rooted seedlings of winter jujube. The gas propagation material was selected from the elite seedlings, or fine. The branches on a single plant can maintain the excellent genetic quality of the winter jujube, and it is difficult to use the roots to propagate all the roots of the superior seedlings, which is easy to cause the mixed of the jujube seedlings. Winter jujube seedlings are the most important link in winter jujube planting. Choose soil with flat terrain and good irrigation and drainage conditions. Salt content. Winter jujube seedlings: After planting winter jujube seedlings, water is poured into the soil, and the water seeps into the soil and is shallow. When sowing, planting at 30 kg per acre, the sowing depth is 2. Whether sowing or secondary seedlings, cover the mulch after sowing or planting. After the new leaves are unearthed from the seedlings, the seedlings and soil are placed one by one. When the winter jujube seedlings grow to more than 25cm, 10kg of diammonium phosphate is applied per acre, and the seedlings are topped to 40-50, and the rootstock is thickened. Soil and fertilizer management and pest control should be strengthened during the growing season. Grafting is carried out with xylem buds or subcutaneous joints, which are carried out from the end of July to August of the current year and from the end of April to the middle of June of the following year. When the buds grow to 30 pm, they are tied up to prevent wind blows and breaks. Water management and pest control.
