Problems solved by technology

The liquid fertilizer suspension made of polyacrylamide, carboxymethyl cellulose and other thickening substances, attapulgite and kaolin as suspending agents is easy to precipitate and flocculate, and stratification will appear after 3-5 days of storage, resulting in uneven fertilizer concentration , the sediment at the bottom cannot flow for a long time, and crystallization is formed due to the high concentration of fertilizer, which eventually causes the intelligent fertilization system to fail to operate normally

Abstract

The invention relates to a preparation method of a liquid fertilizer suspending agent. The preparation method of the liquid fertilizer suspending agent comprises the following steps: (1) adding 5-10 parts of sodium bentonite into 90-95 parts of water, uniformly mixing, heating and stirring until the mixture is colloidal to obtain a material A, (2) uniformly mixing 75-80 parts of biochemical fulvicacid, 10-15 parts of xanthan gum, 5-10 parts of polyvinylpyrrolidone and 5-10 parts of polyethylene glycol 4000 to obtain a material B, and (3) adding 0.2-0.3 part of tetrasodium pyrophosphate into 38.1-41.7 parts of the material A, uniformly mixing, adding 55-58 parts of amino acid liquid, uniformly mixing, adding 3-5 parts of the material B, and uniformly mixing to obtain the liquid fertilizersuspending agent. According to the preparation method of the liquid fertilizer suspending agent, the preparation method is simple, the liquid fertilizer produced by using the liquid fertilizer suspending agent is not layered or precipitated (placed for 3-5 months) after being placed for a long time, and crystallization of the liquid fertilizer can be inhibited to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of liquid fertilizers, and in particular relates to a preparation method of a liquid fertilizer suspension. Background technique [0002] In agricultural production, the application of fertilizers has greatly increased the yield of crops, but with the application of fertilizers, the increase in yield is limited, and the utilization rate of fertilizers applied to the soil is very low. How to do this without increasing the cost of farmers? Improving the utilization rate of fertilizers has become an urgent problem in agricultural production. With the promotion and application of drip irrigation technology, the implementation of water and fertilizer integration can greatly improve the utilization rate of fertilizers. Solid fertilizers cannot exert their fertilizer efficiency well due to the influence of dissolution and dripping time during application. The liquid fertilizer can be miscible with water in any pro...
