Embodiment 1

[0029] Compound microbial fertilizer was prepared according to the following formula: fermented bean cake 48kg, potassium nitrate 37.5kg, diammonium phosphate 12.5kg, nanometer natto powder 1kg, Bacillus subtilis microbial inoculant 1kg.

[0030] The application test of compound microbial fertilizer was done on wheat in the manner shown in Table 1, and compared with conventional compound fertilizer (Saikefu compound fertilizer 12-08-20 potassium sulfate type). The fertilization methods all adopt 70% (mass ratio) of basal fertilizer in ditches and strips, and 30% (mass ratio) of topdressing fertilizer in holes or strips.

Abstract

The invention discloses a composite microbial fertilizer. Based on the weight part of dry basis, the fertilizer is prepared from the following components: 30-60 parts of fermented soybean cake, 20-50 parts of potassium nitrate, 5-20 parts of diammonium phosphate, 0.5-2 parts of nano-grade natto powder and 0.5-2 parts of a bacillus subtilis microbial agent. The composite microbial fertilizer can be used for simultaneously supplying organic nutrition, inorganic nutrition and microbial nutrition to crops, has the characteristic of low sulfur content, can be used for improving soil, preventing soil acidification and improving crop quality, and has a utilization rate which is relatively increased by over 30 percent in comparison with that of simple application of a conventional fertilizer, so that the fertilizer usage is reduced by over 30 percent. The fertilizer is easily available in ingredients, is low in production cost, and is beneficial to large-area popularization and application.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a compound fertilizer containing organic matter, inorganic matter and microbial components. Background technique [0002] Fertilizer is a strategic material to ensure national food security, and it is the material basis for maintaining and improving soil fertility and realizing sustainable agricultural development. Fertilizers can be divided into organic fertilizers, inorganic fertilizers, and biological fertilizers according to their ingredients. Organic fertilizers contain a large amount of organic matter and contain a complete range of nutrients. The application of organic fertilizers increases the content of organic matter in the soil, which can improve soil physical, chemical and biological characteristics, fertilize soil fertility, and improve crop quality. However, organic fertilizers contain low nutrient concentrations. After being applied to the soil, they must be decomposed and rotted b...
