Special organic fertilizer

Abstract

The invention relates to a special organic fertilizer. The mixing mass ratio of an organic fertilizer and a compound fertilizer is 1%, among them, wherein in the organic fertilizer, rotten sheep manure and rotten bagasse are mixed according to a mass ratio of 1:1 to obtain a mixed material, the mixed material is mixed with soil dressing according to a mass ratio of 15%:85%, and in the compound fertilizer, the N: P: K mass ratio is 15%:15%:15%. The novel fertilizer belongs to an independently innovative product and is a slowly released organic-inorganic fertilizer, the fertilizer is low in cost, multifunctional and good in effect, the vegetative growth and reproductive growth of nursery stock can be scientifically regulated and controlled, the physical and chemical properties of soil are improved, the soil structure is improved, microaggregates are formed, and the special organic fertilizer has the advantages of high cation-exchange capacity, and good air permeability, water binding capacity and water permeability. The organic fertilizer provided by the invention is complete in nutrition, can improve the soil properties and easily adjust the nutrient proportion, and is high in nutrient supply speed, high in the mineralization degree of the organic fertilizer, high in fertilizer supply performance and long in fertilizer supply time.

Description

technical field [0001] The invention relates to a special organic fertilizer and belongs to the technical field of fertilizers. Background technique [0002] Foreign advanced forestry developed countries such as the United States, Finland, France and Germany have taken the lead in using special fertilizers, light substrates and self-controlled greenhouses in the process of forest tree seedlings. In recent years, France has taken the lead in developing Fertiss non-woven fabric container seedlings, and light substrates to fill containers. The main nutrients in the light substrates are organic and inorganic fertilizers, which have achieved good results in seedling cultivation. my country's forest tree seedlings have also gone through the process from traditional bare-root seedlings to container seedlings, and the application of fertilizers has changed from ordinary fertilizers to special fertilizers. Due to the lack of special fertilizers and few types of selection in traditio...

AI Technical Summary

Problems solved by technology

Conventional container seedlings have a large capacity, the substrate is too tight, and the air permeability and water permeability are poor, which is not conducive to the growth and development of the root system.
