Grape fruit retention and enlargement method

Abstract

The invention belongs to the technical field of fruit cultivation and discloses a grape fruit retention and enlargement method. The method includes the steps of respectively applying a mixed solution containing gibberellin / alpha naphthyl acetic acid and forchlorfenuron for grapes in the size of a soybean / grapes in the size of a peanut. The grape fruit retention and enlargement method has the advantages of being good for grape safety, good in grape fruit retention and enlargement effect, simple in operation and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for grape fruit preservation and expansion. Background technique [0002] Gibberellin (GA for short) is a widely existing class of plant hormones that regulate growth and affect various developmental processes. As a broad-spectrum plant growth regulator, it can enter the plant body through plant leaves, twigs, flowers, seeds or fruits, and spread to active growth parts to take effect. Such as: stimulating the growth of leaves and buds; promoting seed dormancy, flowering, and gender expression; inhibiting the aging of leaves and fruits, etc. There are at least 126 known gibberellin species and their similar structural chemicals (as of 2003), and gibberellin chemicals are made of A 1 (GA 1 ) to A 126 (GA 126 ), named in order of discovery. A large number of studies have proved that gibberellin exists in all aspects of fruit tree growth and development,...

Problems solved by technology

In the cultivation of stone fruit and seedless fruit, in order to realize the fruit expansion and seedless effect of Kyoho grape, the existing technology uses a higher concentration of GA 3 Dip the grape fruit with the CPPU mixture, but it has caused the following problems in the production of Kyoho grapes: the fruit stem becomes hard and easy to fall off, causing the fruit to fall off; Fruit surface obstacles such as ossified fruit grains; the soluble solid content of fruit grains is slightly reduced, which affects the sugar content of the fruit to a certain extent; it also causes fruit water content to decrease, pulp hardening, etc., resulting in a decline in grape fruit quality

Moreover, the growth of grape vines also causes excessive growth of branches, affects the flower bud differentiation of the next season, and inhibits the flowering rate. In addition, this method of dipping treatment has low efficiency and is difficult to promote and use in large-scale grape planting.

[0006] The patent application number is 200310121614.7 "Fujiminori Grape Grape Grape Fruit Swelling Treatment Method" adopts gibberellin solution or a mixture of forchlorfenuron and gibberellin as the Fujiminor grape swelling agent. In this method, gibberellin, clofenac The high concentration of urea can easily affect the growth of grapes; in addition, the use of the mixed solution in this method is applied by dipping, which is inefficient and difficult to promote and apply in large-scale grape planting
