Specific embodiment
Below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described,
Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the scope of protection of the invention.
Agricultural water-retaining agent based on bamboo vinegar powder is prepared by each component of following mass percent: bamboo vinegar powder 20-26%,
Sodium Polyacrylate 35-46%, polyacrylic acid potassium 10-16%, edible gelatin 0.5-1%, humic acid potassium 10-16%, coconut powder 2-
4% and cocoanut active charcoal 1-3%.
Polyacrylic acid potassium can increase the content of potassium in water-retaining agent, promote crops to absorb the conversion of potassium, polyacrylic acid
Potassium and Sodium Polyacrylate are present in water-retaining agent with tridimensional network, have strongly hydrophilic, pass through the electricity on the outside of intramolecular
It solves the osmotic pressure that matter concentration generates and absorbs moisture, previous evaporation leakage, the rainwater being lost or watering pours water quick storage are got up, side
Just using achieving the purpose that be retained drought resisting when arid；Humic acid potassium in water-retaining agent can generate a large amount of organic matters after decomposing, and be agriculture
Plant growth provides various trace elements, promotes the growth of crop root system, balanced after cocoanut active charcoal absorbs coconut powder
The polysaccharide and albumen in coconut powder are converted, activating soil increases the gas permeability of soil, prevents soil block, is conducive to the life of crop
Long, the vegetable protein in bamboo vinegar powder can increase the nitrogen content in soil, improve the activity and quantity of Soil Microorganism, promote
Decomposition of the microorganism to nutritional ingredient in soil, and then promote plant growth, edible gelatin plays the role of gluing, converts after degradation
It is absorbed for organic matter by crops；The water swelling of agricultural water-retaining agent is released water and is shunk and can increase the gas permeability and granule of soil
Structure improves the activity of microorganism, promotes the growth and development of crop root system.
The preparation method of agricultural water-retaining agent based on bamboo vinegar powder, comprising the following steps:
Step 1, humic acid potassium is dried to moisture content is 9%, then grinding is sieved using the sieve of 80~100 mesh,
Each raw material is weighed by weight percent, bamboo vinegar powder 20-26%, Sodium Polyacrylate 35-46%, polyacrylic acid potassium 10-16%, is eaten
Gelatin 0.5-1%, humic acid potassium 10-16%, coconut powder 2-4% and cocoanut active charcoal 1-3%；
Step 2, after coconut powder, cocoanut active charcoal, edible gelatin being mixed at room temperature, the sieve of 80~100 mesh is used
Sieving；
Step 3, Sodium Polyacrylate, polyacrylic acid potassium and bamboo vinegar powder are uniformly mixed, use the sieve mistake of 80~100 mesh
Sieve；
Step 4, the mixed streams closed in step 1~3 is puddled, is placed in granulating and forming in pelletizer, carry out dehumidifying precipitation,
So that the water content of agricultural water-retaining agent less than 10%, cools down water-retaining agent, storage at room temperature.
When the moisture content of humic acid potassium is greater than 9% in step 1, the mixed viscosity of material is bigger than normal, is unfavorable for being granulated into
Type；Excessively dry after material mixing if moisture content is less than 9%, when granulation, is unfavorable for forming, and granulation time and pressure increase
Greatly, the manufacturing cost of water-retaining agent increases.
Made into using the sieve sieving material of 80~100 mesh this is because material particular diameter crosses conference in step 1~3
Type process is difficult, and material particular diameter is too small, and agricultural water-retaining agent structure more consolidation, the Water-saving effect of preparation are poor；When dehumidifying precipitation
Guarantee that the water content of agricultural water-retaining agent less than 10%, can mitigate the weight of agricultural water-retaining agent, guarantee low moisture environments, convenient for storage agriculture
Woods water-retaining agent.
