Early-maturing shed type pear cultivation method

Abstract

The invention relates to an early-maturing shed type pear cultivation method. Common pear varieties are adopted, a scientific pruning method and conventional water-fertilizer management are combined, fruit trees are planted sparsely in a steel net shed so as to prevent disasters of high wind, hail and the like, mechanized operation is facilitated, daylighting rate of the fruit trees can be increased, and fruit quality is improved; through effective control of stem height, artificial pear flower pollination, fruit thinning, picking and the like are facilitated, evening absorbent of fruit nutrients is benefited, and quality fruit rate is greatly increased; an external drain ditch forms a water circulation in the shed, and the effect by excessive temperature differentials on florescence of the fruit trees is reduced by the aid of specific heat capacity of water. The method is simple and easy to implement, easy to operate and low in investment, no special requirements are caused to the fruit varieties, application of chemicals of ripening agents and the like is not needed during cultivation, chemical residues are lowered, pear quality is obviously improved, big fruit and high yield are achieved, and the early-maturing shed type pear cultivation method is suitable for large-scale promotion and application.

Description

technical field [0001] The invention belongs to the field of fruit tree planting, and in particular relates to an early-maturing shed-type cultivation method for pear trees. Background technique [0002] Pears are temperate fruit trees. Pear trees in central and northern China bloom late, usually in April and May, and mature in September and October, while early-maturing pears usually refer to fruits that mature before early July. In order to promote early fruiting of pear trees, fruit growers often apply a lot of fertilizers, pesticides and ripening agents during the cultivation and management process. Excessive use of chemicals increases the production cost of pear trees and causes excessive chemical residues in pear fruits, which do not meet the requirements of green food. Require. [0003] And, the pear tree that this method accelerates ripening not only yield is lower, and the pear quality and the mouthfeel of output are also relatively poor, therefore, develop a kind...

Problems solved by technology

In order to promote early fruiting of pear trees, fruit growers often apply a lot of fertilizers, pesticides and ripening agents during the cultivation and management process. Excessive use of chemicals increases the production cost of pear trees and causes excessive chemical residues in pear fruits, which do not meet the requirements of green food. Require

[0003] And, the pear tree that this method accelerates ripening not only yield is lower, and the pear quality and the mouthfeel of output are also relatively poor, therefore, develop a kind of can improve pear fruit output and quality, green pear tree early-maturing cultivation method is very useful. necessary
