Method for steel structure grid shed type cultivation of pear trees

Abstract

The invention relates to a method for steel structure grid shed type cultivation of pear trees. Common pear tree varieties and scientific pruning methods are adopted in combination with conventional water and fertilizer management, sparse plantation of fruit trees in a steel structure grid shed facilitates mechanization operation while preventing wind, hail and other disasters, the fruit tree lighting rate can be increased, and fruit quality is improved; by effective control over tree trunk height, artificial pollination of pear flowers, fruit thinning and picking of pears and the like are facilitated, the uniform absorption of fruit nutrient is also facilitated, and the high quality fruit rate is greatly increased. The cultivation method is simple, feasible, easy to operate and less in investment, has no special requirement on the fruit tree variety, also does not need application of chemical reagents such as a ripening agent during the cultivation, reduces chemical residues, obviously improves the quality of the pears, enables the fruits to be large and enables the yield to be high, and is suitable for large-scale promotion and application.

Description

technical field [0001] The invention belongs to the field of fruit tree planting, in particular to a method for cultivating pear trees in the form of a steel grid frame shed. 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, reduce pests and diseases, and improve fruit quality, fruit farmers usually use shed cultivation, and in the process of cultivation management, apply a lot of fertilizers, pesticides and ripening agents. Excessive use of chemicals increases the production cost of pear trees , and cause chemical residues in pome fruit to exceed the standard, which does not meet the requirements of green food. [0003] And, the pear tree of this cultivation method not only yields lower, and the pear quality and mou...

In order to promote early fruiting of pear trees, reduce pests and diseases, and improve fruit quality, fruit farmers usually use shed cultivation, and in the process of cultivation management, apply a lot of fertilizers, pesticides and ripening agents. Excessive use of chemicals increases the production cost of pear trees , and cause chemical residues in pome fruit to exceed the standard, which does not meet the requirements of green food

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