Rape flower thinning pruning method

Abstract

The invention provides a crop pruning method, in particular to a pruning method which can improve the yield per unit area of the rape vegetable flower. The method of the invention is that in March to April, when the florescence of the rape is just over, the young (silique) fruit on the lower end of the anthotaxy comes into being preliminarily, and half of the flowers on the upside of the anthotaxy still do not fade, the technology measurement of pruning (or extirpating) the tip end of the anthotaxy can be conducted to prevent the anthotaxy of the rape from keeping on growing higher and consuming the moisture nourishment, and promote the footstalk on the lower end of the cutting opening to grow thicker, as well as the silique bigger and the purpose of production increase can be achieved with obvious economic benefit.

Description

technical field [0001] The invention relates to a crop pruning method, in particular to a rapeseed (Brassica napus L.) flower-thinning pruning method for improving yield per unit area. Background technique [0002] Pruning is widely used in the production of fruit trees, usually in the planting and juvenile stages, the dry shaping is carried out, and the plants are pruned into a certain shape. Such as the natural happy shape of a peach tree, the evacuated layered shape of a pear tree, etc. At the same time, diseased and insect branches, leggy branches, etc. need to be cut off. The central link is to make the canopy receive sufficient light, the fruit grows robustly, and achieves the purpose of high yield. [0003] The pruning technique is also applied to economic forests such as tea and Kudingcha. [0004] Sesame and soybean topping is to remove the tip of the trunk or branch. [0005] Picking the main moss of rapeseed is also a form of pruning. Rapeseed moss can be eat...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved and the technical task proposed by the present invention are aimed at the problem that the horns (pods) in the upper half of the inflorescence gradually shrink and the useless horns (pods) gradually increase in the process of flowering and fruiting of rapeseed, which affects the rapeseed yield. A method of thinning and pruning rapeseed, to prevent the ineffective growth of the top of the inflorescence and the consumption of water and nutrients, promote the thickening of the pedicels, the enlargement and symmetry of the pods (pods), and achieve the purpose of significantly increasing yield
