Embodiment 1

[0023] Site selection for this example: Heilongjiang Keshan Farm

[0024] Experimental field area: 500 mu

[0025] Time: 2018-2019

[0026] Bacteria agent selection: organic material decomposing agent (Jixin), registration certificate number Microbe Fertilizer (2016) Zhunzi (4758), effective viable bacteria count ≥ 100 million / g.

[0027] A farming method for full return of corn stalks combined with bacterial agents for soybean planting in cold regions, comprising the following steps:

[0028] (1) Mechanized corn stalks are all returned to the field: after the corn is ripe and harvested, the corn stalks are smashed on the spot and evenly scattered in the field. The length of the chopped corn stalks is 4-7cm;

Abstract

The invention relates to a corn straw and microbial inoculum combined full-returning cultivation method for soybean planting in a cold region, and belongs to the field of corn straw returning in the cold region. The method comprises the following steps of mechanically returning corn straws to the field, applying a straw decomposing microbial inoculum, planting soybeans and the like. According to the method, in-situ corn straw returning and cold region soil characteristics are combined, straw returning conditions are scientifically and reasonably controlled, mechanical straw returning is adopted, and the straw degradation rate is effectively increased, the soil fertility is improved, and agricultural non-point source pollution is reduced by adjusting the technical conditions such as returning depth, returning particle size and microbial inoculum application amount; and meanwhile, the production cost is reduced, the yield of crop rotation crops is increased, and the method is a practical field returning mode which is simple in operation procedure, labor-saving, labor-saving and environment-friendly, and is suitable for popularization and application in northeast regions.

Description

technical field [0001] The invention belongs to the field of returning corn stalks to fields in cold regions, and in particular relates to a cultivation method for returning corn stalks combined with bacterial agents to fields for soybean planting in cold regions. Background technique [0002] The three provinces of Liao, Jilin and Hei and the eastern part of Inner Mongolia are the main concentration areas of precious black soil resources in my country, known as the "Golden Corn Belt". The perennial corn planting area here is stable at about 240 million mu, accounting for about 44% of the country's corn planting area. The annual corn output is about 100 billion kilograms, while the corn straw output is as high as 150-180 billion kilograms (some points on the outlet for corn straw in Northeast China) Opinion [J]. Agricultural Machinery Science and Technology Promotion, 2018(1):24-26.). Traditional corn stalk treatment methods are mainly dyeing, feed, composting and so on. A...
