Jujube tree at the beginning of flowering stage

In the first flowering period of jujube tree, the jujube head and the second branch on the jujube head that were sprouted in the same year can be timely took different degrees of topping, which can effectively control the vegetative growth of jujube head, regulate the nutrient distribution of the tree, and reduce the consumption of nutrients. The jujube head grows and consumes nutrients to the reproductive growth, thereby promoting flower bud differentiation and floral organ development, reducing buds, falling flowers and falling fruit, and effectively increasing the fruit setting rate. Juvenile jujube can achieve early results, achieve early high-yield, and achieve the effect of crown control with fruit pressure tree, and extend the cultivated years of densely planted date garden.

The time of Zao Tou topping is different depending on the climate in different regions. Usually at the beginning and the beginning of flowering. Jujube head topping level, depending on the strength of the jujube head and growth site may be. The jujube head with strong growth potential and relatively large space can usually pick up 5-6 secondary branches and then pick up the heart. The jujube head with medium growth and relatively small space can generally retain 3-4 secondary branch toppings; Or the weak, small space of the jujube head, can leave 1-2 second branches after the topping; no growth space of the jujube head, regardless of the strength of growth potential, do not leave the second branch, can stay in the base of the jujube head 5 - Strongly pick up the heart after -7 centimeters and promote the transformation of the base jujube into woody or semi-woody dates.

In addition to the top of the jujube head to pick up the heart, the second branch also depends on the growth potential and the size of the space to carry out different degrees of picking. When there are too many fruits, fruits and vegetables are needed to improve the quality of dates. Use and cultivate woody, semi-woody jujube cranes. In the jujube area of ​​southern Shandong Province, jujube farmers used it as a technical measure for the early high yield of jujube trees and achieved good results. The above is for reference.
