Problems solved by technology

This situation is mainly reflected from the following aspects: the fertilizer has only a single nutrient, which cannot provide comprehensive and reasonable nutrients for crops; after use, the soil is acidified or salinized, and the soil quality is reduced; due to the decline in soil quality, the buffer capacity is greatly improved Reduced, the use of inorganic fertilizers is difficult to achieve results and is likely to cause fertilizer damage; it makes agricultural production fall into a vicious circle and it is difficult to achieve sustainable development

Abstract

The invention discloses composite agricultural fertilizer. The composite agricultural fertilizer is prepared by the following raw materials in parts by weight: 35-40 parts of straw powder, 20-25 parts of ground phosphate rock, 22-24 parts of dolomite dust, 18-20 parts of quick lime, 15-18 parts of shell powder, 12-15 parts of diatomite, 10-13 parts of turf, 7-11 parts of urea, 6-10 parts of monoammonium phosphate, 5-8 parts of potassium chloride, 3-4 parts of zinc sulfate, and 10-13 parts of soil modifier. According to the fertilizer disclosed by the invention, energy and nourishments are provided by plants to improve the utilization rate of the fertilizer, so that the yield and quality of crops are prominently improved; in addition, the soil physicochemical property and soil nutrient status can be effectively improved by the soil modifier, added in the fertilizer, so as to promote the plants to adsorb nutrients and moisture and act positive effects on soil microorganisms.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound agricultural fertilizer and a preparation method thereof. Background technique [0002] Agriculture affects national survival issues and is the basis for other industries. Our country is a big agricultural country, so the development of agriculture directly affects the people's livelihood in our country. At present, the world is facing severe problems such as resource destruction and environmental degradation. As a country with a large population, resources and agriculture, this problem is particularly prominent. This situation is mainly reflected from the following aspects: the fertilizer has only a single nutrient, which cannot provide comprehensive and reasonable nutrients for crops; after use, the soil is acidified or salinized, and the soil quality is reduced; due to the decline in soil quality, the buffer capacity is greatly improved Reduced, the use of ino...
