Problems solved by technology

The preparation process of this kind of compound fertilizer is simple, easy to realize, and low in cost, and can reduce the pressure of subsequent treatment of breeding wastewater in poultry and livestock farms, and has significant environmental, economic and social benefits, but this kind of compound fertilizer only contains inorganic minerals Substances and other elements do not have organic materials. On the one hand, the environmental protection is poor and the cost is high. On the other hand, the promotion effect on the growth of crops is also weak.

Abstract

The invention discloses a controlled-release compound fertilizer rich in various mineral substances and relates to the field of fertilizers. The controlled-release compound fertilizer comprises the following raw materials in parts by weight: 55-70 parts of attapulgite clay, 10-15 parts of crop straw, 10-15 parts of livestock and poultry manure, 5-10 parts of edible fungi residues and 4-8 parts of a soil conditioner. The invention further discloses a production process of the compound fertilizer. According to the compound fertilizer, attapulgite clay is preferred as the main ingredient, and is rich in more than twenty micro-elements including silicon, potassium, calcium, sulfur, iron, magnesium, manganese, iodine, selenium and the like, strong in adsorptivity and good in sustained and controlled release property; and a certain quantity of an organic material is also added into the compound fertilizer to provide enough nutrition for crop production, meanwhile, to condition soil, and to help to improve and optimize soil compositions, so that a favorable ecosystem is maintained, less environmental pollution is caused, environmental friendliness and energy saving are achieved, and the cost is low.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a slow-release compound fertilizer rich in various minerals and a production process of the slow-release compound fertilizer rich in various minerals. Background technique [0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements. Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It is very important for balanced fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. role. But it also has some disadvantages, such as its nutrient ratio is always fixed, but the types, quantities and ratios of nutrient elements required by different soils and different crops are varied. Therefore, it is best to test the soil before use to understand the texture and nutritional status of the soil in the field. In addition, it is also necessary to pay...
