Background
The plant growth regulator is a hormone substance which is widely applied to the agricultural production for regulating the growth and development of plants, can effectively regulate and control the growth and development of plants, enhance stress resistance, increase yield and improve quality, and has the characteristics of small dosage, quick response, less residue and strong pertinence. The effects on growth can be classified into a plant growth promoter, a plant growth inhibitor and a plant growth retardant, which are selected according to plant varieties and application purposes. Common growth promoters are indolepropionic acid, naphthylacetic acid, 6-benzyladenine; common growth inhibitors are triiodobenzoic acid, a juglandins; common growth retardants are uniconazole, paclobutrazol and chlormequat chloride. The research shows that when two or more plant growth regulators are used in a mixed mode or used in sequence, the effect is better than that of single application, and the regulation and control effects are better exerted; however, it is also possible that the use of two or more plant growth regulators in combination inhibits the growth of crops, resulting in lower crop yields or a yield improvement which is less than the effect of the use of a single dose, and therefore rational use of plant growth regulation is of paramount importance.
The preparation of excellent high-yield hybrid seeds by using the regulator is an important method for improving grain yield, the key problem of regulator breeding is to have an excellent regulator with high emasculation rate without affecting female organs, and the emasculation agent is an important agricultural production application of the regulator. The existing emasculation agents are few in variety, most of chemical synthesis products such as maleic hydrazide and the like, and green chemicals lack of the emasculation agents in the market are one main direction of the existing emasculation agent research.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below.
Example 1
Active ingredients a and B were dissolved in water and formulated at different concentrations (table 1).
Table 1: persimmon tannin and chitosan oligosaccharide compound
Application example: indoor potting test verification
Test object: gala small bell pepper (supplied by Harbin golden dragon agriculture Co., ltd.)
The test method comprises the following steps: the experiments were carried out in a glass greenhouse. Uniformly mixing turfy soil and sand according to a mass ratio of 1:1, loading the mixture into a 54 cm-27 cm-6 cm seedling tray, uniformly sowing seeds into the seedling tray, covering a soil layer with a thickness of about 0.5cm, watering from the bottom, and sprouting and seedling under the condition of abundant sunlight at 24-28 ℃. After 2 true leaves of the pepper plants grow, selecting pepper seedlings with consistent growth vigor, transplanting the pepper seedlings into a flowerpot, keeping the growth conditions of each pot seedling consistent, and applying a base fertilizer after seedling reviving, wherein the base fertilizer is conventional compound fertilizer 15-15-15, and the dosage is 600kg/hm 2 And (3) application. The first agent spraying was performed 15 days after transplanting, and the second agent spraying was performed 30 days later, the yield of capsicum was investigated in the fruiting period, each treatment was repeated 5 times, and the test results are shown in table 2.
The reagent is an experiment group reagent, a control group reagent and a blank; wherein the experimental group is a composition of chitosan oligosaccharide and persimmon tannin according to different compounding; the control group is chitosan oligosaccharide or persimmon tannin with different concentrations; the blank is clear water.

From the data, it can be obtained that the persimmon tannin has better wheat emasculation effect compared with the chitosan oligosaccharide mixture, and has optimal effect when the concentration of persimmon tannin and chitosan oligosaccharide is 200mg/L+500 mg/L. The concentration is less than the value, and the emasculation rate is reduced; the concentration is higher than the value, and the castration rate is equivalent.
Table 5: CFR measurement data of wheat relative outcrossing fruiting rate
From the data, it can be obtained that the persimmon tannin has better wheat outcrossing fruiting rate effect compared with the chitosan oligosaccharide mixture, and has optimal effect when the concentration of persimmon tannin and chitosan oligosaccharide is 200mg/L+500 mg/L. The concentration is less than the value, the outcrossing setting rate is equivalent, but the emasculation rate is reduced; the concentration was higher than this, the emasculation rate was comparable, but the outcrossing setting rate was decreased.
As shown in the experiment, when the concentration of the persimmon tannin and the chitosan oligosaccharide is 200mg/L+500mg/L, the persimmon tannin and the chitosan oligosaccharide have optimal wheat emasculation rate and outcrossing setting rate, and the persimmon tannin and the chitosan oligosaccharide are green chemicals, so that the persimmon tannin and the chitosan oligosaccharide are expected to be applied to the agricultural field as green chemical emasculation agents.
The obtained water agent can also act on other crops, has obvious synergistic effect in the aspect of regulating or promoting plant growth, and can improve crop yield and crop quality; can promote the efficacy of chemical hybridization breeding and greatly improve the breeding efficiency. The water aqua can promote agricultural production to raise economic and social benefit.
The above-described embodiments of the present invention do not limit the scope of the present invention. Any of various other corresponding changes and modifications made according to the technical idea of the present invention should be included in the scope of the claims of the present invention.
