Biological fertilizer and preparation method and use method thereof

Abstract

The invention relates to biological fertilizer and a preparation method and a use method thereof. Acid producing bacteria are added into organic fertilizer to obtain the biological organic fertilizer.Through the addition of the acid producing bacteria, organic matters can be fast decomposed; the pathogenic bacterium breeding and crop disease occurrence can be reduced; the crop yield is improved.

Description

technical field [0001] The invention relates to a biological fertilizer and its preparation and use method. Background technique [0002] At present, the following problems exist in my country's cultivated land: 1) Unreasonable fertilization and irrigation have caused serious secondary salinization of soil; 2) Unreasonable fertilization has caused soil compaction and reduced fertilizer use efficiency; 3) The trend of soil acidification is obvious; 4) Soil conservation The fertilizer performance is poor, and the fertilizer will be lost with the water, causing groundwater pollution. [0003] Microbial fertilizers can improve soil fertility, improve crop quality, reduce fertilizer usage, and increase fertilizer utilization efficiency, but the effect of biological fertilizers is greatly affected by the selected microorganisms. And biological fertilizers also have the following disadvantages, 1) Fertilization is too shallow, because biological fertilizers contain organic matter a...

Problems solved by technology

[0002] At present, the following problems exist in my country's cultivated land: 1) Unreasonable fertilization and irrigation have caused serious secondary salinization of soil; 2) Unreasonable fertilization has caused soil compaction and reduced fertilizer use efficiency; 3) The trend of soil acidification is obvious; 4) Soil conservation The fertilizer performance is poor, and the fertilizer will be lost with the water, causing groundwater pollution

[0003] Microbial fertilizers can improve soil fertility, improve crop quality, reduce fertilizer usage, and increase fertilizer utilization, but the effect of biological fertilizers is greatly affected by the selected microorganisms

And biological fertilizers also have the following disadvantages, 1) Fertilization is too shallow, because biological fertilizers contain organic matter and have the effect of water retention, so it creates conditions for the reproduction of harmful bacteria, which can easily cause soil-borne diseases and endanger the growth of crops; 2) Fertilization is too deep, and the biological fertilizer is isolated from the air after deep burial, resulting in the death of most bacterial strains, resulting in the inability of the microbial fertilizer to degrade in the ground, or the degradation time is too long, unable to provide energy for the crops; the undegradable organic matter exists in the ground for a long time, It will affect the respiration of the root system of later crops, easily cause rotten roots, and affect crop yield; 3) Anaerobic bacteria are used. At present, anaerobic bacteria produce organic acids after anaerobic fermentation. Excessive organic acids will further cause soil acidification and heavy metals 4) The low microbial activity and slow degradation rate will also result in the inability to provide energy for crops; the long-term storage of undegradable organic matter in the ground will affect the respiration of the root system of crops in the later stage, easily cause rotten roots, and affect Crop yield; 5) Microorganisms in biofertilizers are vulnerable to the attack of "indigenous microorganisms" in the soil, cannot survive, and cannot take advantage of biofertilizers

[0004] At present, there is no solution to the problems of soil-borne diseases caused by biological fertilizers, slow fermentation, rotten roots of crops, affecting crop yield, acidifying soil, and microorganisms cannot survive.
