Problems solved by technology

Fertilizer is not easy to penetrate into the leaves, and the water droplets of liquid fertilizer will slide down from the surface, resulting in the loss of fertility, resulting in an increase in fertilizer use and a decrease in yield increase
In addition, certain heavy metal elements or chemical fungicides and antibacterial agents in organic water-soluble fertilizers may cause harm and pollution to human body and environment.

Abstract

The invention provides an organic water-soluble fertilizer comprising a variety of macro elements and trace elements. With the organic water-soluble fertilizer, nutrients needed by crop growth can be comprehensively supplemented, crop better growth can be regulated, crop yield can be substantially improved, dose is low, and cost is low. The fertilizer has good popularization value. According to the organic water-soluble fertilizer, n-butanol and fatty alcohol polyoxyethylene ether are added as leaf penetration wetting agents, such that foliar absorption of nutrients can be improved, and fertility higher-efficiency utilization can be facilitated. A main component of the fertilizer is modified natural high-molecular polysaccharide with relatively high repelling and inhibiting effects against crop pests and diseases. The component can be used for replacing chemical insecticide or fungistat with toxic or side effect in traditional organic water-soluble fertilizers. The novel organic water-soluble fertilizer is safe and environment-friendly. The fertilizer can naturally degrade in the nature, and has the advantage of low dose. Compared to that of traditional organic water-soluble fertilizers, the cost of the organic water-soluble fertilizer provided by the invention is reduced by approximately 10%. The organic water-soluble fertilizer has the three advantages of high efficiency, environment friendliness, and low cost.

Description

technical field [0001] The invention prepares a novel chitosan organic water-soluble fertilizer, which belongs to the field of agricultural fertilizer preparation. Background technique [0002] In recent years, in order to increase the output and quality of food, vegetables and fruits, people pay more and more attention to the use of fertilizers, and organic water-soluble fertilizers, as a new type of high-efficiency fertilizer, have also attracted more and more attention. The production and application of organic water-soluble fertilizers in my country are developing very rapidly, and there are more and more types of organic water-soluble fertilizers on the market. Organic water-soluble fertilizers are formulated from one or more of macronutrients, medium and micronutrients, and their main function is to provide and supplement crop nutrition in a targeted manner, improve the growth of crops, and then increase the yield of crops; There are also some biologically active subs...
