深翻地的作用是:1.改善土壤结构,提高肥力土地种植一茬作物后,由于降雨、灌溉以及人、畜、机的压力等自然因素和人为因素的影响,表层土壤下沉,土壤结构受到破坏,使其变得板结,透水、透气性不良,土壤微生物活动减弱,下层土壤有效养分得不到利用。通过深翻地,可以打破土壤犁底层,增加了松土层的厚度,改善了土壤理化性状,下层生土上翻,使之熟化,既改善了土壤结构,又提高了土壤肥力。
The role of deep plowing is: 1. To improve the soil structure, improve fertility After planting a crop of land, due to rainfall, irrigation and human, livestock, machine pressure and other natural and man-made factors, the surface soil subsidence, soil structure Damaged, so that it becomes compacted, water permeability, poor air permeability, soil microbial activity weakened, the lower soil available nutrients are not utilized. Through deep plowing, the bottom layer of soil plow can be broken, the thickness of loose layer can be increased, the physical and chemical characters of soil can be improved, and the lower layer of raw soil can be turned upside down to make it mature, which not only improves soil structure but also improves soil fertility.
