Problems solved by technology

[0002] Excessive soybean planting area and continuous cropping for many years have resulted in single consumption of nutrients in cultivated land, deterioration of land physical and chemical properties, aggravation of diseases, insect pests and weeds, and changes in soil enzyme systems that are not conducive to the growth of soybeans. Soybeans have shown a downward trend. Habits are not easy to change, the transfer of a large number of young and strong labor force in rural areas and the large application of long-residual herbicides, etc., the problem of continuous cropping of soybeans is difficult to be solved in a short period of time

Embodiment 1

[0008] A plot that has not been planted with soybeans in northern Anhui was selected as the experimental plot. The experimental area was 10 mu, the experimental field was 5 mu, and the control field was 5 mu. The soybeans were sown in mid-May and harvested around October. Conventional fertilization method fertilizes the test field and the control field, and the fertilizers are chemical fertilizers, and the amount of each application is applied to the same type. In addition, when the test field is fertilizing each time, the chemical fertilizer weight 3-5% of the present invention is additionally added to the chemical fertilizer. Microbial agents were applied together, and after 5 years of continuous cropping, the results are as follows:

Abstract

The invention relates to the technical field of a microbial agent, more specifically to the technical field of a microbial agent for fertilizers. The microbial agent is prepared by the following steps: using ryegrass meal, sesbania gum, compound amino acids powder, charcoal dust and yeast extract as raw materials, inoculating brevibacterium flavum and acetobacter aceti, and fermenting at 30-33 DEG C for 68-70 h. The obtained microbial agent is especially suitable for continuous cropping soybean plantation, can effectively adjust pH value of soil during soybean continuous cropping plantation period, raise content of organic matter in the soil, increase contents of total nitrogen, rapidly available phosphorus and rapidly available potassium in the soil, increase bacteria number of beneficial bacteria in the soil, inhibit proliferation of harmful fungi and reduce disease pest and weed, and is of positive significance for enhancing yield of continuous cropping soybean and improving properties of continuous cropping soil.
