Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of agricultural machinery, and particularly relates to a green manure residual body crushing and rolling integrated equipment. BACKGROUND

[0002] Green manure is mainly based on planting specific plants of legume (Chinese milk vetch, alfalfa, etc.) and gramineae (ryegrass, oat, etc.), and is an ecological fertilization technology for realizing soil improvement and nutrient supply by turning under the field at the biomass accumulation peak. Its action mechanism shows multiple synergistic effects: firstly, the soil nitrogen supply is improved through biological nitrogen fixation; secondly, the input of organic matter after the biomass is turned under the field can form microaggregates to physically store carbon, accumulate inert carbon components through microbial action, enhance the stability of the soil carbon pool and provide long-term carbon sink capacity; thirdly, the plant residues and deep root systems jointly improve soil water regulation, reduce evaporation and runoff loss and enhance the soil drought and flood resistance; and finally, the green manure creates a loose and nutrient-rich microenvironment for crop root development, promotes crop yield increase and quality optimization. This green fertilization mode integrating soil improvement, carbon sink enhancement, water regulation and yield increase builds a virtuous cycle system of "improving soil, fixing carbon, conserving water and increasing yield" through the synergistic interaction of organisms and soil, provides a systematic solution with ecological safety and production sustainability for agricultural green transformation and becomes a core technical path supporting agricultural carbon neutralization.

[0003] Compared with chemical fertilizers, the application of green manure can effectively reduce the surface pollution caused by nitrogen and phosphorus loss and reduce the carbon footprint of agricultural production, so it is widely promoted in organic farms, high-standard farmlands and other scenes and becomes a core technical path for reducing the amount of chemical fertilizers and increasing efficiency and fixing carbon and increasing yield.

[0004] However, the existing green manure harvesting process has the core defect of low resource utilization rate. In actual operation, the combine harvester can only effectively collect about 60%-70% of the fresh and tender stems and leaves on the upper part of the plants, and the lower stems close to the ground are still left in the field due to the mechanical cutting table operation blind area, high lignification degree of the stem base and other reasons, causing waste of green manure resources, and the prolonged decomposition period of the residual lower stems causes a gap in nitrogen supply for the seedling stage of the following crops; at the same time, the uneven distribution of residual stems in the field is easy to form a breeding area for diseases, pests and weeds.
