Description
Technical Field
The invention relates to the technical field of agricultural fertilizers, in particular to a preparation method of an organic fertilizer.
Background
In order to meet the requirement of agricultural modernization development, the production of chemical fertilizers is developing towards high-efficiency compounding, fertilization mechanization, fertilizer transportation pipelining and water-fertilizer sprinkling irrigation instrumentation besides continuously increasing the yield. Liquid ammonia, ammonium polyphosphate, potassium polyphosphate and the like become main chemical fertilizer varieties which are vigorously developed due to the advantages of high nutrient concentration or few side ingredients. Many chemical fertilizers also tend to be prepared into fluid fertilizers, and trace element fertilizers and pesticides are mixed into the fluid fertilizers to form multifunctional compound fertilizers, so that the multifunctional compound fertilizers are convenient for combination of pipeline transportation and fertilization and irrigation (sprinkling irrigation and drip irrigation), and have the advantages of labor saving, water saving and fertilizer saving. With the development of facility agriculture (such as plastic greenhouse, etc.), the demand of vegetables, melons and fruits for carbon dioxide fertilizer will gradually increase. However, long-term application of chemical fertilizers in large quantities often leads to environmental pollution. In order to keep the agricultural ecological balance, organic fertilizers are advocated to be used together with chemical fertilizers so as to meet the nutrient requirements of crops and simultaneously avoid the deterioration of soil properties and environmental pollution.
The average effective utilization rate of the chemical fertilizer is low, the utilization rate of the chemical fertilizer is generally 30-40% in China at present, the effective utilization rate of the chemical fertilizer is generally 50% in developed countries abroad, and the effective utilization rate of the chemical fertilizer is up to 70% in part. Because the chemical fertilizer can not be fully utilized in the application, a large amount of chemical fertilizer is lost every year, and pollution and harm are caused to water and the atmosphere. Therefore, pollution-free environment-friendly fertilizers are urgently needed. Therefore, a preparation method of the organic fertilizer is provided to solve the problems.
