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 excessiv...

Embodiment 1

[0021] At the beginning of April 2013, at the double-season grape demonstration base of the Academy of Agricultural Sciences of Guangxi Zhuang Autonomous Region, 10-year-old Kyoho grapes were treated with 10ppm gibberellin (GA 3 )+1.8ppm forchlorfenuron mixed liquid spray fruit. Observed 10 days after full flowering, the fruit setting rate of the control was lower, while the gibberellin (GA 3 ) + forchlorfenuron mixture treatment, the ear fruit set rate is moderate. When harvesting, the fruit appearance products were all better than the control, and the difference between the internal quality index and the control was not obvious (see Table 1 for details).

[0022] Table 1 GA3+CPPU mixed solution of the present invention is to the fruit preservation effect of Kyoho grape

[0023]

[0024] Remarks: The control is Kyoho grapes that are conventionally planted and have not been treated for fruit protection

Embodiment 2

[0026] At the beginning of October 2013, at the double-season grape demonstration base of the Academy of Agricultural Sciences of Guangxi Zhuang Autonomous Region, 10-year-old Kyoho grapes were treated with a mixed solution of 14ppm α-naphthaleneacetic acid + 2.5ppm forchlorfenuron 2 weeks after full flowering (the fruit is the size of a peanut grain) Spray fruit. When harvesting, it was found that the appearance of the fruit was better than that of the control, and the difference between the internal quality index and the control was not obvious (see Table 2 for details).

[0029] Remarks: The control is conventionally planted Kyoho grapes that have been treated for fruit retention but not expanded

Embodiment 3

[0031] At the beginning of April 2014 (Xia Guo), at the Guangxi Zhuang Autonomous Region Academy of Agricultural Sciences Mingyang Shuangji Grape Demonstration Base, 3 days after full flowering of the 3-year-old Kyoho grapes (the fruit particles are the size of soybeans), 11ppm gibberellin (GA 3 )+2.0ppm forchlorfenuron mixed solution to spray fruit (preserve fruit). 12-14 days after preserving the fruit (the fruit is the size of a peanut grain), spray the fruit (inflated) with a mixture of 14ppm α-naphthalene acetic acid+1.9ppm forchlorfenuron. After harvesting, it was found that the appearance of the fruit was better than that of the control, and the difference between the internal quality index and the control was not obvious (see Table 3 for details).

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,...
