Efficient green micro-crystallized mineral-biological compound fertilizer and production method thereof

Abstract

The invention discloses an efficient green micro-crystallized mineral-biological compound fertilizer and a production method thereof. The compound fertilizer comprises the following components in parts by mass: 7-9 parts of N, 7-9 parts of P2O5, 7-9 parts of K2O, 25-30 parts of organic matters, 8-12 parts of humic acid, 3-6 parts of amino acid and 15-20 parts of chemical elements such as calcium,silicon, magnesium, selenium, molybdenum, boron and zinc, as well as not less than 0.02 billion/kg of available active bacteria. The efficient green micro-crystallized mineral-biological compound fertilizer has the beneficial effects of being capable of adapting to acidic-alkaline soil and neutral soil in various regions, improving the soil, enhancing the adsorption ability of the soil on nutrients, preventing nitrogen and potassium from being washed away by water due to a large amount of rainfall, reducing formation of insoluble phosphate and improving fertility of the soil; and in addition,nitrogen, phosphorus and potassium in the original soil can be activated to be absorbed by crops by virtue of microelements contained in the fertilizer, and the supply capability of the deep soil nutrients can be enhanced, thus the physiochemical indexes and biological environment of the soil can be improved in case of long-term application, hardened soil can be reduced, and the quality of crops can be obviously improved.

Description

technical field [0001] The invention relates to a microcrystalline mineral biological compound fertilizer and a production method thereof. Background technique [0002] The eutrophication pollution of Taihu Lake and other inland water systems has become a major concern of governments from the central to local levels, which is related to the long-term sustainable development and social stability of the region. Due to many reasons such as the lack of awareness of environmental protection by the majority of farmers for a long time, the extensive farming activities, and the neglect of non-point source pollution, the non-point source pollution in planting, breeding and living areas is relatively serious. It has been found that the application of chemical fertilizers in agriculture is the main cause of agricultural non-point source pollution. However, high-efficiency agriculture is inseparable from the support of fertilizers. Exploring a fertilizer that can meet the needs of crop...

Problems solved by technology

At present, the agricultural biological fertilizers developed and put on the market at home and abroad can be roughly divided into five categories: one is the growth hormone that stimulates the growth and development of plants; the second is the microbial fertilizer that accelerates the decomposition of organic matter and releases the nutrients needed by plants The third category is nitrogen fixation, but so far, the nitrogen fixation effect of this kind of biological agents is only effective for legumes Practical significance; the fourth category is biological agents that use biological reactions to release mineral-fixed nutrients. This type of fertilizer can activate phosphorus, potassium and other trace elements fixed in the soil, but long-term fixed-point application will consume mineral nutrients in the soil. The fifth category is bio-organic-inorganic compound fertilizers mixed with microorganisms, organic fertilizers and chemical fertilizers. This type of fertilizer often loses biological activity due to high salt content and high osmotic pressure, making it difficult for microorganisms to survive.
