New girdling-free management technology of winter jujube tree

Abstract

The invention provides a new girdling-free management technology of a winter jujube tree. The technology comprises the following steps: keeping the phloem part, taking one tenth of diameter value as a width, on a trunk of the triennial winter jujube tree older than 3 years not stripped at one time; and annularly stripping the remaining nine tenths of the phloem part in the width of 5cm. By means of the technology, a plurality of girdling of the winter jujube tree every year is substantially changed into one-time completion within a year, and girdling is not required any more, thus achieving the purpose of completing girdling once and for all. The technology has the beneficial effects of effectively controlling vegetative growth and promoting reproductive growth of the winter jujube tree, reducing over 90% of workload in operations such as pinching, bud picking, branch picking, pruning and the like which need to be repeatedly implemented every year, saving labor and money, preventing diseases, controlling and dwarfing a crown, promoting coloration and sweetening and improving the fruit-setting rate and the high-quality fruit rate. The new girdling-free management technology provided by the invention has the advantages of obvious effect, greatly lowered management cost and labor intensity and unprecedented great significance, and is simple in operation.

Description

Technical field: [0001] The invention provides a new technology for once-and-for-all girdling-free management of winter jujube trees, which belongs to the field of high-quality and high-efficiency cultivation of fruit trees. Background technique: [0002] Girdling is an indispensable and necessary technology for the high-yield and high-quality management of winter jujube trees. It has a history of more than one thousand years in my country and is still used today and is indispensable. The conventional girdling technique of winter jujube trees is very labor-intensive. Since modern winter jujube trees are cultivated with short crowns and densely planted, people who girdle must adopt squatting, kneeling, climbing, drilling, bending, lying, crawling, cuddling, hugging, pressing, etc. Various actions such as pressing, hooking, picking, and scraping can be completed, which is time-consuming and labor-intensive, and each peeling must be performed with more than 5 times of girdling ...

AI Technical Summary

Problems solved by technology

If you want to hire people to do it, generally a winter jujube tree needs to be girdled more than 5 times at least once, each time is 0.5 yuan, three times a year, and the girdling fee for such a winter jujube tree is more than 7.5 yuan, plus this technology. The cost of budding, topping, thinning, pruning, etc. alone costs more than 15 yuan per plant, not counting the application of chemical fertilizers, pesticides, watering, picking, transportation, and disease damage. According to the average yield of 15 catties of winter jujube trees, 56 winter jujube tr...
