Shaping and trimming method of facility jujube trees

Abstract

The invention discloses a shaping and trimming method of facility jujube trees. The method includes following steps: 1), determining trunks after planting; 2), shaping and trimming in the year of planting; 3), shaping and trimming in the second year of planting; 4), shaping and trimming jujube trees in the third year of planting and in a fruiting period. By applying the novel shaping and trimmingmethod of the facility jujube trees, a first main branch jujube head is reserved at the top of each jujube tree in the fruiting period to horizontally extend and grow along a direction perpendicular to jujube tree planting lines, top end advantages of the first main branch jujube heads are utilized, germination and growth of other jujube heads are controlled, and double effect of jujube head growing and fruiting can be realized, so that workload of pinching and bud picking of the jujube trees in the growing period can be reduced greatly, labor intensity and labor cost are reduced, growth of branches and leaves of the jujube trees can be improved, light utilization rate is increased, consecutive-year high yield of the jujube trees is ensured, commodity fruit rate is increased, and development of facility jujube tree industry is promoted.

Description

technical field [0001] The invention relates to the field of jujube tree planting, in particular to a method for shaping and pruning jujube trees in facilities. Background technique [0002] Jujube is a unique economic tree species in my country. It has a long history of cultivation. The planting area of ​​jujube in the country has reached 30 million mu. It has become one of the leading industries in my country's agriculture and has made great contributions to ecological construction and farmers' income. With the sharp increase in domestic jujube cultivation area and output and the situation of oversupply, coupled with the impact of climate change, regional precipitation has increased significantly, and the red jujube industry has undergone historic changes, forming production, quality, price, The overall decline in benefits has directly affected the production enthusiasm of the majority of jujube farmers, seriously threatening and hindering the sustainable development of th...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of shaping and pruning method for facility jujube trees in view of the problems in the above-mentioned prior art that jujube tree shaping and pruning has a large workload, high cost, and ineffective results. Leave the first main branch at the top of the jujube tree to prolong its growth, and scientifically take into account the dual effects of jujube tree growth and fruiting, which can greatly reduce the workload of topping, bud wiping and fruit thinning during the jujube tree growth period, and reduce labor intensity and labor costs , at the same time, it can increase the growth of jujube branches and leaves, improve the utilization rate of light energy in the growth process of jujube trees, ensure the high yield of jujube trees year after year, and increase the rate of commercial fruit
