Soluble silicon-nitrogen-kalium liquid fertilizer

Abstract

The invention belongs to compound silicon fertilizer, in particular relates to soluble silicon-nitrogen-kalium liquid fertilizer, wherein silicon is soluble silicon existing in the form of silicate so as to be beneficial to being absorbed by crops completely, and the fertilizer can be used to cereal crops or leaf surfaces of other silicon-like crops. The preparation method of the fertilizer comprises the following steps: adding proper amount of fulvic acid aqueous solution in a reaction kettle, heating the solution and adding citric acid solid powder in the solution; slowly adding potassium metasilicate liquid into the reaction kettle and continuously stirring; adding ethylene diamine tetracetate manganese solid powder into the reaction kettle, continuously stirring and keeping constant temperature; adding sodium of polyaspartic acid liquid, polyethyleneglycol aqueous solution and compound potassium aqueous solution into the reaction kettle in sequence, continuously stirring and keeping constant temperature. After being sprayed on leaf surfaces of crops, the invention can obviously strengthen the fall resistant capability and the disease and insect pest resistant capability of crops, promotes the growth of the crops, enhances the seed set propagation coefficient and increases the thousand seed weight, thereby enhancing the yield.

Description

technical field [0001] The invention provides a fertilizer, especially a compound silicon fertilizer. Background technique [0002] Silicon fertilizer is a new type of fertilizer. At present, most of the silicon fertilizers produced in China are insoluble or citric acid-soluble silicon fertilizers, with low soluble silicon content. Even soluble potassium silicate liquid fertilizers are not easy for crops to absorb without the coexistence of relevant organic acids, and the residual amount is large. , fertilizer efficiency is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a soluble silicon nitrogen potassium liquid fertilizer, wherein the silicon is soluble silicon existing in the form of silicate, so as to facilitate complete absorption by crops and improve fertilizer efficiency. [0004] The present invention is achieved in that a kind of soluble silicon-nitrogen-potassium fertilizer is made by follo...
