Brassinolide-containing compound formula fertilizer as well as preparation method and application thereof

Abstract

The invention discloses a brassinolide-containing compound formula fertilizer and a preparation method thereof. The brassinolide-containing compound formula fertilizer comprises basic nutrient fertilizer of nitrogen, phosphorus and potassium, and is characterized by comprising brassinolide, potassium cocoyl glycinate, polyether modified heptamethyltrisiloxane and cetostearyl alcohol; the brassinolide accounts for 0.001 to 1.0 percent of the basic nutrient fertilizer by mass; the potassium cocoyl glycinate accounts for 1 to 10 percent of the basic nutrient fertilizer by mass; the polyether modified heptamethyltrisiloxane accounts for 2 to 3 percent of the basic nutrient fertilizer by mass; the cetostearyl alcohol accounts for 1 to 2.5 percent of the basic nutrient fertilizer by mass. The brassinolide-containing compound formula fertilizer can improve soil hardening and soil physical and chemical properties, enhance the capacities of retaining water, retaining fertilizer and supplying fertilizer of the soil, protect crops, reduce diseases, and greatly improve the stress resistance to disease resistance, insect resistance, drought resistance, cold resistance and the like, has a sustained-release effect, can improve the utilization rate of the fertilizer, and does not pollute the environment.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a compound formula fertilizer containing brassinolide and its preparation method and application. Background technique [0002] Fertilizer is an essential material support for promoting plant growth and increasing crop production, and it is also one of the important conditions for the development of agricultural production. China is one of the countries that consume a lot of agricultural fertilizers in the world. At present, the common fertilizers on the market are high-concentration solid fertilizers with relatively single components, such as urea, nitrophosphate fertilizer, etc. The above fertilizers can only provide a large amount of nutrients such as nitrogen, phosphorus, and potassium. elements, the various grains, vegetables and fruits produced cannot meet the requirements of green organic food. [0003] Compound fertilizer refers to chemical fertilizers conta...

AI Technical Summary

Problems solved by technology

The compound fertilizers of the prior art are mainly composed of nitrogen, phosphorus, and potassium. Although they can increase the yield, the elements needed for crop growth are not limited to this. Simply applying a large amount of chemical fertilizers such as nitrogen, phosphorus, and potassium will reduce the amount of organic matter in the soil. Decrease, the performance of the aggregate structure is reduced, the phenomenon of soil compaction is intensified, and the ability to retain fertilizer and water is reduced; at the same time, a large number of microorganisms die, the soil microbial flora changes, many beneficial microorganisms change from dominant populatio
