Description
Technical Field
The invention relates to the technical field of agricultural science, in particular to an instant round particle potash fertilizer granulation auxiliary agent and a use method thereof.
Background
The instant fertilizer, also called water-soluble fertilizer, is a multi-element compound fertilizer capable of being completely dissolved in water, can be quickly dissolved in water, can be more easily absorbed by crops, and has relatively high absorption utilization rate. More importantly, the fertilizer can be applied to facility agriculture such as irrigation, sprinkling irrigation, infiltrating irrigation, drip irrigation and the like, so that water and fertilizer integration is realized, and the effects of saving water, fertilizer and labor are achieved. It is more than one time higher than the absorption and utilization rate of common fertilizer. In the growth stage of crops, the nutrition consumption is large and fast, and people need to adopt a water-soluble fertilizer which is quick-acting, fast-supplementing and instant.
The powdery potash fertilizer is a fertilizer with a high dissolution speed, and after being prepared into granules, the dissolution speed is greatly reduced, and the problem of too low nutrient release speed exists in the process of using the additional fertilizer.
The potash fertilizer is one of three kinds of nitrogen, phosphorus and potassium fertilizers, the raw material of the potash fertilizer belongs to sylvite, and sandy materials are difficult to granulate into balls. The granulation effect of the potash fertilizer is improved by adding a viscous material to prepare the granular potash fertilizer, but the dissolution speed of the granular potash fertilizer is obviously reduced due to the self-adhesive property of the viscous material and the reduction of the specific surface area of the granular potash fertilizer.
The granulating agent is generally a viscous material, and can play a role in increasing the cohesiveness of the material and improving the granulating effect and the strength of the granules when added into the potash fertilizer powder, but also can slow down the dissolution speed of the granules in water, so that the quick release of nutrients of the granular potash fertilizer in the use process is not facilitated, and especially when the potash fertilizer is used for additional manuring, the quick release of the nutrients of the granular potash fertilizer is more important.
Disclosure of Invention
The invention aims to provide an instant round particle potash fertilizer granulation auxiliary agent and a use method thereof.
The technical scheme adopted by the invention is as follows:
an instant round particle potash fertilizer granulation auxiliary agent is characterized by comprising the following components: 1-20 parts of ammonium nitrate, 1-20 parts of binder and 1-20 parts of thickener, dissolving the three substances in water, and adjusting the viscosity of the solution to a proper value through the thickener to obtain the instant round granular potash fertilizer granulation auxiliary agent.
The binder is one or a mixture of polyvinyl alcohol and polyacrylamide.
The thickener is one or more of starch, acacia, pectin, agar, gelatin, alginate jelly, carrageenan, and dextrin.
And adding an instant round granular potash fertilizer granulation auxiliary agent accounting for 1-10% of the weight of the potash fertilizer in the process of granulating the powdery potash fertilizer, and drying and screening to obtain the instant round granular potash fertilizer.
The potash fertilizer is one or a mixture of more than two of potassium sulfate, potassium chloride or potassium nitrate.
