Crop high-yield regulation and control method adopting microbial fertilizer and straw returning deep ploughing mode

Abstract

The invention discloses a crop high-yield regulation and control method adopting microbial fertilizer and a straw returning deep ploughing mode. The method comprises the following steps: crushing previous crop stubble straw, returning the straw to the field, and applying a compound fertilizer base fertilizer, a solid microbial organic fertilizer and a microbial decomposition agent; after previous crops are harvested, completing fertilizer application, deeply ploughing soil through a moldboard turnover plow, and then carrying out land leveling through a rotary cultivator; in the next year and the third year, adopting rotary tillage with three years a as a cycle; and carrying out sowing, irrigating, weeding and disease and pest control until the crops are mature, and harvesting the crops. According to the method, microbial materials are applied, harmful bacteria in soil can be inhibited, root growth is promoted, and root activity is improved; and in the later stage of crop growth, root system aging is delayed, good water and fertilizer absorption is kept, overground photosynthetic production and later-stage substance transfer are effectively supported, the fertilizer utilization rate is increased, and the economic yield is increased.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a high-yield control method for crops in the mode of returning microbial fertilizers and straws to fields for deep plowing. Background technique [0002] Under the traditional planting mode of winter wheat and summer corn in the North China Plain, the unreasonable planting mode such as single rotary tillage measures and long-term high-intensity chemical fertilizer application has caused soil compaction, shallow plow layer, and nutrient solidification, etc. The problem of quality decline, which in turn causes low nutrient utilization efficiency, and excessive nutrients enter the natural environment such as the atmosphere and groundwater, which will cause serious environmental problems. [0003] In addition, in recent years, straw returning has become one of the main agronomic measures in the region. However, due to the frequent alternation of soil drought and flood...

Problems solved by technology

[0002] Under the traditional planting mode of winter wheat and summer corn in the North China Plain, the unreasonable planting mode such as single rotary tillage measures and long-term high-intensity chemical fertilizer application has caused soil compaction, shallow plow layer, and nutrient solidification, etc. The problem of quality decline, which in turn leads to low nutrient utilization efficiency, and excessive nutrients enter the natural environment such as the atmosphere and groundwater, which will cause serious environmental problems

[0003] In addition, in recent years, straw returning has become one of the main agronomic measures in the region. However, due to the frequent alternation of soil drought and flood caused by the monsoon climate in North China, it is difficult to retain soil humus. Activation will also increase soil carbon emissions
