Winter jujube tree topping method capable of promoting jujube expansion

Abstract

The invention belongs to the technical field of plant cultivation, relates to a winter jujube tree topping method capable of promoting jujube expansion and aims to overcome the defects that wide application of hormone affects quality of winter jujubes in the prior art and jujube expansion is poor by existing topping methods. The winter jujube tree topping method capable of promoting jujube expansion comprises the steps as follows: parts between first auxiliary branches and second auxiliary branches of skeleton branches of jujube trees in the full-bloom period are selected as topping parts, andthe healing time of top openings is controlled to be 50-60 days; the jujube orchard is comprehensively managed through fertilizer and water management, reasonable loading, timely thinning and pest control after topping. Results show that by means of the topping manner, the cultivation purposes that the weight of single jujube can be increased, the sugar content can be increased, jujubes have bright color, stable fruit shapes, thin peel, good tastes and good flavor are achieved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and particularly relates to a method for opening the nails of winter jujube trees for promoting the expansion of jujube fruits. Background technique [0002] The winter jujube tree is a typical fresh jujube variety. It has a history of more than 10 years from the development of the variety to the current large-scale promotion and cultivation. Its fruit is rich in nutrients, high in sugar, rich in vitamin C, and has good taste and quality. The reputation of "King" is favored by consumers, but with the rapid expansion of the cultivation area, the output of winter jujube is also increasing rapidly year by year, and consumers have higher and higher requirements for the consumption level of jujube fruit. In order to promote the expansion of jujube fruit, regardless of food safety, jujube farmers use expansion hormones indiscriminately, but the size and color are significantly reduced, and th...

Problems solved by technology

[0006] In order to overcome the technical deficiencies of the high hormone usage in the method for promoting jujube fruit expansion in the prior art or the unsatisfactory expansion of jujube fruit after conventional carapaces, the invention provides a method for promoting jujube fruit expansion. The trunk branch of winter jujube tree opens nails and prolongs the healing time of the nails, which significantly promotes the expansion of jujube fruit
