Description

Organic compound fertilizer prepared from gadfly manure and application thereof
Technical Field
The invention belongs to the technical field of fertilizers, and particularly relates to an organic compound fertilizer prepared from gadfly manure and application thereof.
Background
After long-term application of the fertilizer, nutrients cannot be effectively absorbed and utilized by crops, and chemical substances such as nitrogen, phosphorus, potassium and the like are easily solidified by soil to form various chemical salts which are accumulated in the soil to cause structural imbalance of soil nutrients, deterioration of physical properties, and over-standard of partial harmful metals and harmful germs in the land, so that the soil properties are deteriorated. The long-term excessive application of the nitrogen fertilizer can cause the loss of elements such as calcium, magnesium and the like, so that the soil is continuously acidified, and the productivity is finally lost. The application of chemical fertilizers can also cause the quality of products to be reduced, if a certain chemical fertilizer is applied to a certain part, the crop nutrition is disordered, the transformation and synthesis of partial substances in the body are blocked, and the quality of the products is reduced. For example, the current melons and fruits are not sweet, vegetables are not fragrant, and are easy to rot and cannot be stored, and the reason is that chemical fertilizers are applied to the melons and fruits excessively. In addition, long-term chemical application can cause environmental pollution, and substances such as excessive chemical fertilizers and soil water-soluble nutrients are leached into underground water and rivers by rainwater and farmland irrigation water to cause pollution to the underground water and the rivers in partial areas, so that the underground water, the rivers and lakes are eutrophicated, the underground water is not drunk well, and fish and shrimps in partial rivers and lakes are dead. Finally, the application of the fertilizer leads to the increase of production cost, only the cost is increased in agricultural production without increasing yield, and the phenomena that low-quality agricultural products are not easy to sell or the price is low and the like are caused, thereby bringing loss to farmers.
At present, although the use of organic fertilizers has been popularized in agricultural production, the utilization of livestock manure is still a problem which is difficult to overcome. For example, the total amount of liquid dung and excrement discharged by the cultivation growers of medium and large livestock and poultry in China per year exceeds 17 hundred million tons, and a large amount of excrement is accumulated around the cultivation farm, so that the pollution problems of breeding of germs and flies, rotten odor diffusion, eutrophication and the like are easily caused. Aiming at the problem of treatment of the excrement of the poultry and livestock, a novel biological resource, namely the hermetia illucens is introduced, the hermetia illucens is a biological with a powerful nutrition enrichment effect, beneficial nutritional ingredients in the excrement can be enriched and converted into high-quality hermetia illucens body protein, and the economic value is improved while the excrement of the poultry and livestock is treated efficiently. However, the horsefly dung generated by metabolism of black soldier flies becomes a novel pollution source, and no report about reasonable utilization of the horsefly dung exists at present.
