Embodiment 1

[0037] A growth regulator for improving peach fruit setting rate according to the present invention includes the following raw material components: gibberellin and auxin, the auxin is naphthaleneacetic acid (NAA), specifically, the gibberellin can be GA3 or GA4+7, gibberellin GA3 is ninety-two. The weight ratio of raw materials gibberellin and auxin is: 7:1 to 7.5:1, wherein, when the raw material is analytically pure, the weight ratio of gibberellin and auxin is preferably 7:1; if commercially available , a purity of 75% gibberellin crystalline powder and a purity of 80% naphthalene acetic acid former powder, then the weight ratio of gibberellin crystalline powder and naphthalene acetic acid former powder is 7.5:1.

[0038] The adjustment method for improving the peach fruit setting rate by using the above-mentioned growth regulator is as follows: spraying the growth regulator 10 days to 15 days after the peach blossoms.

[0039] In the above embodiment, in order to effectiv...

Embodiment 2

[0043] A growth regulator for improving peach fruit setting rate of the present invention comprises the following raw material components: gibberellin and auxin, and the auxin is sodium naphthalene acetate. The weight ratio of the raw materials gibberellin and auxin is 7:1.

[0044] Adopt above-mentioned growth regulator to carry out the adjustment method that improves peach fruit setting rate with embodiment 1.

Embodiment 3

[0046] A kind of growth regulator that improves peach fruit setting rate of the present invention comprises following raw material components: gibberellin and auxin, and described auxin is indole acetic acid (IAA). The weight ratio of the raw materials gibberellin and auxin is 7:1.

[0047] Adopt above-mentioned growth regulator to carry out the adjustment method that improves peach fruit setting rate with embodiment 1.

Abstract

The invention relates to the technical field of fruit growing and in particular relates to a growth regulator for improving the fruit setting rate of peaches and a regulating method. The growth regulator comprises the following components of gibberellin and auxin, wherein the auxin may be one of 1-Naphthalene acetic acid, sodium alpha-naphthyl acetate, indoleacetic acid, phenylacetic acid, indolebutyric acid, indoleacetic acid and 2,4-dichlorphenoxyacetic acid, and the growth regulator is sprayed after the peaches bloom. The growth regulator provided by the invention is easy to obtain and prepare and low in economic cost, and can effectively remedy deficiency of endogenous hormone caused by poor fertilization of peaches; the method for applying the growth regulator provided by the invention is simple and convenient and easy to operate and control, effectively solves the problem that in the growing of peaches, the fruit setting rate is influenced by abnormal weather in a flowering phase, shriveled flower buds, overly rapid warming and the like, improves the fruit setting rate by more than 34 times, and is obvious in effect and applicable to popularization and application in the production of peaches in common peach orchards, green houses and other facilities.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a growth regulator and a regulation method for improving peach fruit setting rate. Background technique [0002] In recent years, in order to improve economic benefits, the area and output of peaches in solar greenhouses, greenhouses and other facilities have been greatly developed, which has promoted the progress of production models and technologies to a certain extent. In the process of technology implementation, problems such as insufficient dormancy and rapid temperature rise are not uncommon because farmers are eager to rush to the market to promote early fruit ripening. For this reason, in many places, heavy pruning is used to control the crown after harvesting, but if the pruning is not timely, the differentiation of flower buds will not be complete. The flower buds of peach trees are of the summer-autumn differentiation type. They began to differentiate i...
