Problems solved by technology

[0007] Although the blended fertilizers disclosed in the above prior art can be formulated and fertilized according to the principle of supplementing what is lacking, the blended fertilizers belong to the series of large chemical fertilizers. After a large amount of application for a long time, it will still damage the soil structure, and then affect the quality of the crops. Growth and development, leading to decline in yield and quality

Abstract

The invention discloses a blended fertilizer containing seaweed extract as well as a preparation method and application of the blended fertilizer, and belongs to the technical field of blended fertilizers and preparation thereof. The blended fertilizer is prepared from the following raw materials in parts by weight: 100-160 parts of seaweed extract, 190-250 parts of urea, 400-460 parts of diammonium phosphate, 80-150 parts of potassium chloride and 70-130 parts of medium trace element particles, wherein the seaweed extract is obtained by extracting seaweed active substances from seaweed cellsby using a biological enzyme method, and the medium trace element particles are prepared by mixing boron, zinc, calcium oxide and magnesium oxide and extruding the mixture. According to the present invention, the seaweed extract is adopted as the raw material, such that the rich minerals and the rich trace elements in the seaweed are substantially retained, the soil cannot be damaged, the purposesof formulated fertilization and reasonable fertilizer use can be achieved, and the effects of soil structure improving and crop growth and development promoting can be provided.

Description

technical field [0001] The invention belongs to the technical field of blended fertilizer and its preparation, and in particular relates to a blended fertilizer containing seaweed extract, a preparation method and application thereof. Background technique [0002] Blended fertilizers, also known as BB fertilizers and dry blended fertilizers, are chemical fertilizers containing any two or three of the three nutrients nitrogen, phosphorus, and potassium. They are made from unit fertilizers or compound fertilizers through simple mechanical mixing. , there is no significant chemical reaction during the mixing process. It is especially suitable for areas with large land area, complex soil types and a wide variety of crops. [0003] The relevant research reports of blended fertilizers in the prior art mainly include: [0004] CN110713419A discloses a special controlled-release blended fertilizer containing bacteria and anti-heavy cropping garlic. The fertilizer is made of the fo...
