Problems solved by technology

[0005] However, there are many defects in the existing organic fertilizers. First, the existing organic fertilizers are generally made of animal manure and plant stalks, which are easy to agglomerate and harden, causing the fertility to be difficult to disperse; second, the existing organic fertilizers have single functions. It only has the function of providing nutrients, and has little effect on improving soil quality and moisturizing; third, the fertilizer effect time of existing organic fertilizers is unstable, and most organic fertilizers still have a relatively short fertilizer effect time
[0006] Based on the above citations, the existing silicon fertilizer production process is complicated, the cost is high, and the existing organic fertilizer has a single function, is easy to agglomerate and harden, and has a short fertilizer effect period.

Abstract

Belonging to the technical field of agriculture, the invention specifically provides a compound long-acting slow-release organic fertilizer with animal dung as the main raw material and diatomite as the main auxiliary material. The compound long-acting slow-release organic fertilizer is mainly prepared from 55-65 parts by weight of biogas residue obtained by pig manure anaerobic fermentation, 20-25 parts by weight of diatomite, 10 parts by weight of edible fungus rod waste, 5-6 parts by weight of a fermentation inoculum, and 10-20 parts by weight of harmless treatment products of pigs dying of illness. The compound long-acting slow-release organic fertilizer provided by the invention contains rich silicon and other elements needed by crop growth, and has more comprehensive nutritional ingredients. Especially through effective compounding of all the raw materials, the effect of long-term slow-release of fertility is achieved. On the basis, the compound long-acting slow-release organic fertilizer also has the effects of maintaining moisture, loosening soil and improving the soil fertilizer conservation performance.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a compound long-acting slow-release organic fertilizer with animal manure as the main raw material and diatomite as the main auxiliary material. Background technique [0002] Agriculture is the guarantee of national economic and social development. In order to improve crop quality and yield in modern agriculture, increasing farming density and increasing fertilizer application are the most commonly used technical means. Among the types of fertilizers, chemical fertilizers such as nitrogen fertilizers, potassium fertilizers, and phosphorus fertilizers produced in batches and on a large scale in the chemical industry are the main ones. The advantages of this type of chemical fertilizers are fast absorption and quick results. Long-term slow release, and after a large amount of application, the lost nutrients will also cause serious environmental pollution and damage ...
