Embodiment 1

[0022] Embodiment 1 Coating agent enhancer reduces the problem of active ingredient loss when coating treatment and storage

[0023] The preparation of the coating synergist used in this embodiment is as follows:

[0024] 1. Mix zeolite (400 mesh) and attapulgite (colloidal grade, 400 mesh) evenly according to the mass ratio of 2:5, and then add water to the mixture to form a suspension with a concentration of 20g / L;

[0025] 2. Add ammonia water (8ml / L) to the suspension obtained in (1), and stir (120rpm) at 40 degrees Celsius for 60 minutes;

[0026] 3. Use a high-energy electron beam (2MeV, 15kGy) to irradiate the suspension for 2 minutes, then dry and pulverize it to 400 mesh;

[0027] 4. Combine the compound obtained in (3) with chitosan (deacetylation degree: 60%), oligosaccharide (glucosamine: 95%, amino oligosaccharide 3%), S-abetin (ABA: 0.06%) , indole butyric acid: 0.9%), and polyvinyl alcohol are uniformly mixed according to the mass ratio of 4000:200:100:1:100, ...

Embodiment 2

[0036] The effect of embodiment 2 coating agent enhancing agent prolonging coating agent persistence period

[0037] The preparation of the coating synergist used in this embodiment is as follows:

[0038] 1. Mix zeolite (500 mesh) and attapulgite (colloidal grade, 500 mesh) according to the mass ratio of 3:7, and then add water to the mixture to form a suspension with a concentration of 40g / L;

[0039] 2. Add ammonia water (10ml / L) to the suspension obtained in (1), and stir (170rpm) at 50 degrees Celsius for 8 minutes;

[0040] 3. Use a high-energy electron beam (8MeV, 40kGy) to irradiate the suspension for 5 minutes, then dry and pulverize it to 500 mesh;

[0041] 4. Combine the compound obtained in (3) with chitosan (deacetylation degree: 90%), oligosaccharide (glucosamine: 95%, amino oligosaccharide 3%), S-abetin (ABA: 0.06%) , indole butyric acid: 0.9%), and polyvinyl alcohol are uniformly mixed according to the mass ratio of 6000:500:200:2:100, which is the synergist ...

Embodiment 3

[0045] The effect of embodiment 3 coating agent reinforcing agent on improving corn seedling emergence rate

[0046] Experimental group: Add the enhancer of this embodiment to the corn coating agent according to the mass ratio of 10% (urea: chlorpyrifos = 9:1 (weight ratio), wherein chlorpyrifos is produced by Zhejiang Xinnong Chemical Co., Ltd., with a purity of 98.5 %) in the coating.

[0047] Control group: do not add enhancer of the present invention, only use corn coating agent (urea: chlorpyrifos=9:1 (weight ratio), wherein chlorpyrifos is produced by Zhejiang Xinnong Chemical Co., Ltd., purity is 98.5%) on corn seed coating.

[0048] The emergence rate of corn was calculated 15 days after sowing, and the emergence rate of corn in the experimental group was 93%, and the emergence rate of corn in the control group was 83.56%.

[0049] It can be seen that the coating agent added with synergist increases the emergence rate of corn by 11.3% compared with the control.

Abstract

The invention relates to a coating agent reinforcing agent. The coating agent reinforcing agent is prepared from, compound particles of zeolite and attapulgite, chitosan, oligosaccharide, abscisic acid and polyvinyl alcohol, wherein the compound particles formed by the zeolite and the attapulgite are subjected to ammonia water treatment and high-energy electron beam irradiation. The coating agent reinforcing agent can improve the adhesion ability of a coating agent on crop seeds, reduce loss of effective components of the coating agent during storage or after sowing and improve the water retention performance of the crop seeds.

Description

technical field [0001] The present invention generally relates to the field of agricultural preparations, in particular to a coating agent enhancer and its preparation method and application. Background technique [0002] In order to suppress pests and diseases and promote crop germination, many crops usually need to be coated before sowing. Traditional coating agents mainly include nitrogen, phosphorus, potassium, pesticides, phytohormones and other ingredients. If the coated seeds are stored for a period of time before sowing, the coating agents on the seeds are prone to exposure to wind, sun, rain, etc. Peeling or loss, which will affect the growth effect of crops after sowing. Moreover, the traditional coating agent still has the problems of low adhesion and weak water retention performance. After sowing, the active ingredients of the coating agent will transfer to the surrounding environment due to leakage, runoff or volatilization in the soil, and it is easy to gradua...
