Abstract
The invention discloses a formula of a slow release farming fertilizer, the active components are decomposed cow dung, plant ash, superphosphate as a base fertilizer, and a composite fertilizer, and the active components comprise 10-30% of the decomposed cow dung, 40-65% of plant ash, 5-10% of superphosphate as the base fertilizer, and 10-20% of the composite fertilizer. The components can provide full nourishment for seedling growth, a high-molecular polymeric material is polyhydroxyalkanoate, the high-molecular material is capable of wrapping the active components in the material to form the slow release farming fertilizer, an adhesive is added in the active components, the adhesive is a biological adhesive, the adhesive has no toxic and harmless on crops, can effectively bond the active components of the fertilizer to a bulk state, so that wrapping by the high-molecular material is convenient.
Description
technical field [0001] The invention relates to the field of agriculture, in particular to a formulation of slow-release agricultural fertilizer. Background technique [0002] my country is a big agricultural country, and agriculture is a pillar industry in our country. In order to increase the productivity of agriculture, agricultural personnel generally use more fertilizers to stabilize and increase production. This extensive fertilization method will cause a large amount of fertilizer loss while increasing production, which will reduce the utilization rate of fertilizers and increase agricultural costs. Contents of the invention [0003] A formulation of slow-release agricultural fertilizer, the components of which include: active ingredients, polymer materials and surface oil. [0004] Preferably, the effective ingredients include: decomposed cow dung, plant ash, general calcium as base fertilizer and compound fertilizer. [0005] Preferably, the content of each com...
