The invention discloses a facility cultivation method of a winter jujube tree. The facility cultivation method of the winter jujube tree comprises the circulatory management steps of selecting varieties, planting and establishing a garden, performing ridging cultivation, performing management before covering a greenhouse, performing management in the greenhouse, performing management after harvesting and performing management before covering the greenhouse, wherein the step of performing ridging cultivation also comprises the steps of performing fertilizer and water management and performing shaping and pruning management; the step of performing management in the greenhouse comprises the steps of performing environmental regulation and control, performing artificial pollination, thinning flowers and fruits, and performing plant disease and insect pest prevention management; and the step of performing management after harvesting comprises the steps of performing branch thinning management, delaying short pruning, pulling branches and applying a base fertilizer in autumn. By the method, through building of a warm winter type greenhouse and through adjustment of the growth and development condition of the winter jujube tree under the facility condition, the ripening time of the winter jujubes are more dispersive, the picking period is longer, the yield is higher and the fruit product is more excellent.

Description

technical field [0001] The invention relates to a plant cultivation method, in particular to a protected cultivation method of winter jujube. Background technique [0002] Zhanhua Dongzao is one of the most distinctive and advantageous agricultural products in Shandong Province.

In recent years, jujube farmers have used a lot of chemical fertilizers and hormones. Although they can artificially increase the size of the fruit and increase the yield, it has caused a serious decline in quality. In addition, in order to catch up with the Mid-Autumn Festival and Nation...

Problems solved by technology

However, ordinary Zhanhuadongzao (i.e. diploid Zhanhuadongzao) also has disadvantages such as small fruit, large core, poor early fruit and high yield, poor cold resistance and storage resistance, and easy to be harmed by diseases and insect pests.

In recent years, jujube farmers have used a lot of chemical fertilizers and hormones. Although they can artificially increase the size of the fruit and increase the yield, the quality has seriously declined.

In addition, in order to catch up with the Mid-Autumn Festival and National Day, and to facilitate long-distance transportation and long-term storage, the phenomenon of picking and selling green greens is very serious, which intensifies the degradation of the quality of Zhanhua Dongzao
