Mineral microbial fertilizer and preparation method thereof

Abstract

The invention discloses a mineral microbial fertilizer. The mineral microbial fertilizer is mainly prepared from the following raw materials in parts by weight: 20-40 parts of fertilizer-grade calcium hydrogen phosphate, 20-40 parts of phosphogypsum, 10-18 parts of organic carbon, 1-7 parts of a bactericide, 2-5 parts of ammonium chloride and 3-5 parts of potassium chloride. A preparation method of the mineral microbial fertilizer comprises the following steps: a, mixing the raw materials; b, fermenting; a, adding the bactericide; d, drying and smashing; and e, cooling and packaging. The mineral microbial fertilizer disclosed by the invention has the advantages that the mineral microbial fertilizer not only has multiple effects in growth promotion, yield increase, bacteriostasis, disease resistance and soil improvement and restoration but also can provide nutrient elements necessary for growth for crops, and effect of the mineral microbial fertilizer is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of fertilizers, more specifically to the technical field of microbial fertilizers. Background technique [0002] With the development of modern agriculture, the use of chemical fertilizers has become indispensable, and the long-term excessive use of chemical fertilizers will seriously damage the soil aggregate structure, reduce air permeability, reduce aerobic microbial activity, and slow soil maturation, resulting in soil compaction , hinder the normal water absorption of crop roots and affect plant growth; excessive use of chemical fertilizers will also lead to a gradual increase in the number of harmful bacteria in the soil, while beneficial bacteria cannot be replenished, resulting in soil flora imbalance; in addition, the lack of plant growth in chemical fertilizers The necessary trace elements such as iron, zinc and manganese, long-term use will lead to the shortage of trace elements in the soi...

[0002] With the development of modern agriculture, the use of chemical fertilizers has become indispensable, and the long-term excessive use of chemical fertilizers will seriously damage the soil aggregate structure, reduce air permeability, reduce aerobic microbial activity, and slow soil maturation, resulting in soil compaction , hinder the normal water absorption of crop roots and affect plant growth; excessive use of chemical fertilizers will also lead to a gradual increase in the number of harmful bacteria in the soil, while beneficial bacteria cannot be replenished, resulting in soil flora imbalance; in addition, the lack of plant growth in chemical fertilizers The necessary trace elements such as iron, zinc and manganese, long-term use will lead to the lack of trace elements in the soil, affecting the growth and development of plants, resulting in reduced crop yield, reduced quality, and reduced ability to resist diseases and damage

Although there are many types of common organic fertilizer nutrients, which can improve soil physical, chemical, and biological properties, fertilize the soil, and provide comprehensive nutrition for plants, their nutrient content is low and the release is slow, which makes it difficult to meet the nutrient needs of crops when they grow vigorously. Moreover, the weight is heavy and the volume is large, and storage and transportation are not very convenient.

Microbial fertilizer is a biological fertilizer produced by one or several kinds of beneficial microorganisms through industrial culture and fermentation. It increases the supply of plant nutrients through the life activities of microorganisms contained in it, leading to the improvement of plant nutritional status, thereby increasing the Yield, while the current common microbial fertilizers contain low nutrient content, poor fertilizer efficiency, and the effect of increasing production is not very ideal, and because the preparation method is not very reasonable, resulting in the survival of the microbial flora contained in it during the production and preparation process The rate is low, which greatly affects the efficacy of microbial fertilizers
