Problems solved by technology

Most of the microorganisms contained in the above-mentioned biological fertilizers are traditional nitrogen-fixing, phosphorus-dissolving and potassium-dissolving bacteria. Although they can improve the utilization rate of nutrients in the soil by crops, they do not have the effect of improving the physical and chemical properties of the soil.
However, due to the extensive use of chemical fertilizers, soil physical and chemical properties have deteriorated, such as soil acidification, compaction, and fertility decline, making it no longer suitable for the growth needs of crops. Just considering how to improve the utilization rate of nutrients in the soil cannot fundamentally solve the problem. The problem of increasing crop yield and making agricultural production sustainable

example 1

[0027] (1) Take 100kg of walnut shells with a moisture content of less than 20%, then cut or crush them, put them into a carbonization furnace, carbonize at 320°C for 30 minutes, cool down to room temperature when the charcoal is produced, and then dry the charcoal to obtain biochar.

[0028] (2) The mixed bacterial solution is obtained by the following methods:

[0029] a. Add 50 kg of chicken manure into a fermenter equipped with fermentation liquid, and ferment aerobically at 35° C. for 45 hours to obtain chicken manure bacteria liquid; the composition of the fermentation liquid is: 20 kg of soybean powder, 10 kg of starch, and 20 kg of molasses , water 70kg;

[0030] b. Insert the Bacillus subtilis strain into a fermenter equipped with a fermentation broth with an inoculation amount of 0.3%, and perform aerobic fermentation at 35° C. for 45 hours to obtain a Bacillus subtilis bacterial fluid; the fermentation fluid consists of: glucose 6%, dipotassium hydrogen phosphate 1...

Abstract

A preparation method of a microbial fertilizer is characterized in that the microbial fertilizer is prepared through mixing 400-800kg of charcoal, 10-20kg of potassium fulvate, 30-60kg of a mixed bacterial liquid, 80-105kg of cow hair powder, 10-25kg of Chinese chestnut barbed shell particles, 10-20kg of banana skins, 10-20kg of sweet potato skins, 2-3kg of walnut skins, 10-20kg of bentonite, 5-6kg of sodium citrate and 3-4kg of magnesium stearate. The fertilizer prepared in the invention has a good yield increasing effect.

Description

technical field [0001] The present invention relates to the preparation method of fertilizer, in particular, relates to the preparation method of microbial fertilizer. Background technique [0002] In agricultural production, long-term and large-scale application of chemical fertilizers can increase the yield of crops to a certain extent, but excessive use will lead to a decrease in soil organic matter content, unbalanced soil nutrient supply, environmental pollution, and soil acidification. The state of trace elements decreased, the types and quantities of soil enzymes decreased significantly, the nutrient competition among soil organisms was fierce, and the stability of soil biological communities decreased. Therefore, with the continuous use of chemical fertilizers, the amount of use shows a gradual upward trend, but the utilization rate of chemical fertilizers shows a gradual downward trend. The main reason is that the long-term use of chemical fertilizers changes the so...
