Fertilizer and water management method for delayed harvesting of wine apples

Abstract

The invention discloses the technical field of agriculture, and particularly relates to a fertilizer and water management method for delayed harvesting of wine apples, the method comprises the following steps that before the wine apples are picked, autumn base fertilizer application is carried out, and 2 kg / plant compound fertilizer and 400 L / plant total irrigation amount are topdressed in the growth period of fruit trees on the basis of the original 2000 Jin / mu compound fertilizer; first topdressing is carried out in the germination stage of the fruit trees, the topdressing amount is 30% to 40% of the total topdressing amount, and the rest topdressing amount is carried out in a fruit expansion stage; and before soil is frozen in winter, first irrigation is carried out, the irrigation amount is 17% to 20% of the total irrigation amount, the rest irrigation amounts are carried out for four times in the germination period, the flowering period, the flower bud differentiation period and the fruit expansion period respectively, and the four irrigation amounts are the same. The method can effectively guarantee the yield and quality of the wine apples, reduce the influence on the growthand development of the fruit trees, achieve the continuous supply of apple ice wine raw materials, and promotes the further development of the apple processing industry.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a fertilizer and water management method for delayed harvesting of wine apples. Background technique [0002] Apple ice wine is made from naturally frozen apples on apple trees as the main raw material and brewed. After the apple fruit is fully ripe, it is appropriate to pick it late, so that it can be alternately frozen and thawed in a natural cold environment to promote the accumulation of sugar, and the soluble solid content reaches more than 20%, resulting in a unique flavor change. Naturally frozen apples are used as raw materials to brew apple ice wine. The alcohol content is 7-12 degrees. The wine is full-bodied, fruity and mellow, golden and bright in color. The production of apple ice wine can not only digest a large number of non-commercial fruits and alleviate the problem of overproduction, but also increase benefits through deep processing, create higher econom...

AI Technical Summary

Problems solved by technology

Because the brewing of apple ice wine requires the fruit to be left on the tree for later harvesting, the fruit will maintain a growth state on the fruit tree, consume the nutrients of the tree body, and cause the accumulation of nutrients in the tree body to decrease, which will affect the growth and development of the fruit tree in the second year and reduce the yield.
