Problems solved by technology

Willow catkins generally appear in April and May, and many people are affected by catkin allergies, asthma and other diseases every year. In addition, due to the uncertainty and flammability of willow catkins falling, it will also affect the driver's sight and easily cause fire problems
[0003] At present, the types of flocculant inhibitors commonly used in the market are single, mainly based on plant growth regulators and hormones. They inhibit the production of catkins by inhibiting the growth of willow buds. Although they have certain effects, they inhibit the normal growth of willows and exist certain disadvantages

Embodiment 1

[0025] In the first step, add 0.5wt% sodium carboxymethylcellulose into cold water for soaking for 6 hours, then raise the temperature to 40°C and stir thoroughly for 3 hours to obtain a uniformly dispersed suspension of sodium carboxymethylcellulose;

[0026] In the second step, 0.5wt% glycerol was added to the sodium carboxymethylcellulose suspension, followed by 0.1wt% Tween-20 and 0.1wt% Span-80, after stirring for 2 hours, 0.01wt% Potassium fulvate, fully stirred and dissolved for 1h;

[0027] The third step is to use fruit vinegar to adjust the pH to 6-8, and then add Bacillus subtilis to obtain the flocculant.

Embodiment 2

[0029] In the first step, add 0.8wt% sodium carboxymethylcellulose into cold water for soaking for 8 hours, then raise the temperature to 50°C and stir thoroughly for 3 hours to obtain a uniformly dispersed suspension of sodium carboxymethylcellulose;

[0030] In the second step, 0.8wt% of glycerol was added to the sodium carboxymethylcellulose suspension, followed by 0.2wt% of Tween-20 and 0.2wt% of Span-80, after stirring for 2 hours, adding 0.03wt% Potassium fulvate, fully stirred and dissolved for 1h;

[0031] The third step is to use fruit vinegar to adjust the pH to 6-8, and then add Bacillus subtilis to obtain the flocculant.

Embodiment 3

[0033] In the first step, add 0.6wt% sodium carboxymethylcellulose into cold water for soaking for 4 hours, then raise the temperature to 45°C and stir thoroughly for 3 hours to obtain a uniformly dispersed suspension of sodium carboxymethylcellulose;

[0034] In the second step, 0.5wt% glycerol was added to the sodium carboxymethylcellulose suspension, followed by 0.2wt% Tween-20 and 0.2wt% Span-80, after stirring for 2 hours, 0.02wt% Potassium fulvate, fully stirred and dissolved for 1h;

[0035] The third step is to use fruit vinegar to adjust the pH to 6-8, and then add Bacillus subtilis to obtain the flocculant.

Abstract

The invention discloses a preparation method of a flocculating inhibitor. The preparation method comprises the following steps of 1, preparing a soluble vegetable gum solution or a sodium carboxymethyl cellulose suspension with viscosity, 2, weighing 0.5-0.8 wt% of glycerin, 0.1-0.2 wt% of tween-20 and 0.1-0.2 wt% of span-80 according to the mass percentage, sequentially adding the glycerin, the tween-20 and the span-80 into the soluble vegetable gelatin solution, and adding 0.01-0.03 wt% of potassium fulvic acid after the glycerin, the tween-20 and the span-80 are fully dissolved, and 3, adjusting the pH value to 6-8 by using an acidity regulator, and then adding bacillus subtilis to obtain the flocculating inhibitor. Fly catkins can be effectively coagulated, compared with an existing flocculating inhibitor, substances such as plant hormones and growth regulators are not added, bacillus subtilis is added as a fungicide, degradation of a film agent can be accelerated, the influence on plants is reduced, the cost is low, and the method is simple and feasible.

Description

technical field [0001] The invention belongs to the technical field of agricultural application, and in particular relates to a flocculant and its preparation method and application. Background technique [0002] Willow catkins have always been a common phenomenon in spring in my country. The root is that willows spread seeds through the wind. Due to the characteristics of fast growth and good shading and greening effects, willows are widely planted in urban centers. Therefore, every spring It has caused a serious problem of willow catkins flying. Willow catkins generally appear in April and May, and many people are affected by catkin allergies, asthma and other diseases every year. In addition, due to the uncertainty and flammability of willow catkins falling, it will also affect the driver's sight and easily cause problems such as fire. [0003] At present, the types of flocculant inhibitors commonly used in the market are single, mainly based on plant growth regulators a...
