Organic fertilizer

Abstract

The invention relates to an organic fertilizer. The organic fertilizer is prepared from the following raw materials in parts by weight: 45-60 parts of chicken manure, 15-22 parts of plant powder, 8-15parts of mixed meal, 10-20 parts of kieselguhr, 3-8 parts of silkworm feces, 1.5-2 parts of fungicide and 0.7-1.5 parts of leavening agent. According to the invention, chicken manure is taken as a main raw material of the fertilizer and is rich in nutritional ingredients, such as nitrogen, phosphorus, potassium, and the like, required by crops; taking dry feces as the raw material is capable of avoiding the existence of parasite and parasite eggs; the plant raw material, silkworm feces, and the like are prepared at reasonable ratio, so that the organic fertilizer is more complete in nutritionand has a certain water-retaining property and insect-resistant effect; the fertilizer provided by the invention turns waste into wealth, is not added with any inorganic fertilizers and is capable ofrelieving the vicious circle of soil environment quality so as to maintain sustainable cultivated land utilization; the fertilizer preparation process is simple; a conventional fermentation process can be adopted for producing the fertilizer; the water content of the product is strictly controlled, so that the fertilizer can be stored for a longer period and can be more conveniently transported,stored and used.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to an organic fertilizer made from chicken manure as a main raw material. Background technique [0002] Fertilizer is a kind of substance that provides one or more essential nutrients for plants, improves soil properties, and improves soil fertility. It is one of the material bases of agricultural production. At present, the area of ​​fruit and vegetable planting in rural areas is increasing, the amount of livestock breeding is decreasing, and the fertilizers for crops mostly rely on inorganic chemical fertilizers as base fertilizers and topdressing fertilizers, resulting in the reduction of soil organic matter, the decline in fertilizer and water retention performance, and a large amount of nutrients applied to the soil permeate and lose , fixed or volatilization loss, excessive accumulation of heavy metal elements, and undegradable chemical pesticides for pest control and d...

Problems solved by technology

In the production process of pollution-free products, it is necessary to control the production environment of agricultural products, especially pay attention to the rational application of fertilizers. Excessive fertilizers are likely to cause environmental pollution and negatively affect the quality of agricultural products.

Many studies have shown that the application of organic fertilizers can effectively solve the harm caused by chemical fertilizers to the soil, and has great potential for achieving high-quality and high-yield crops. However, the current organic fertilizers have problems such as serious loss of nutrients and slow fertilizer efficiency.
