Simple jujube tree pruning method

Abstract

The invention discloses a simple jujube tree pruning method. The method comprises the following steps: performing direct seeding on wild jujube and establishing an orchard in the first year, and cultivating wild jujube seedlings, so as to meet the grafting requirement of the next year; grafting jun-jujube species in the spring of the next year, remaining five secondary shoots and pinching when jujube heads grow to be about 50cm in the same year, and remaining 5-7 sections of the secondary shoots and pinching; heavily pinching all newly eared jujube head shoots in the growth period of the third year starting from late April; remaining 30cm brush stumping for the jujube head shoots grafted in the first year in the spring of the fourth year; heavily pinching 1-2 jujube shedding shoots on the base of all the eared jujube heads in the growing season of the fifth year; and facilitating lignifications of jujube shedding shoots, and forming lignified jujube shedding shoots. According to the technical scheme disclosed by the invention, aiming at a direct seeding jujube orchard with the row spacing of 0.5*2.0m, a tree form pruning manner through which the tree management method is simple and easy to master, the tree structure is simple, the tree is short and intermediate cutting is not needed is found.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a simple pruning method for jujube trees. Background technique [0002] The jujube industry in southern Xinjiang has developed rapidly, especially the invention of live-streaming gardening technology has enabled the rapid development of Xinjiang jujube. At present, the area of ​​Xinjiang jujube is more than 7 million mu. Direct seeding is a highly dense planting method. The main tree shape is small canopy and sparse layered. The spacing between plants and rows is 0.5×1.5 meters or 0.5×2.0 meters. Fruit farmers use groups to increase production and obtain economic benefits. With the growth of jujube tree age, the tree body is constantly expanding, the canopy is airtight, the artificial labor intensity increases, the ventilation and light transmission decrease rapidly, the yield and quality decline, and the damage by diseases and insect pests is serious, causing gre...

Problems solved by technology

Due to the tall tree body, the tree body management technology is complicated, and pruning methods such as topping, bud wiping, branch pulling, short pruning, and retraction are required. It is difficult to control diseases and insect pests, and the labor intensity is high.
