The normal requirements of cultivated soil
The normal land requirements
Seedbed requirements
Covered with weeds and plant debris land
Crop growth layer has very poor scabies, need whole
Reclaiming wasteland
The tillage layer has hardened, need to break the harden layer
Normal plough has everything into and turning over the soil, the weeds and cropsremains were buried function. Now, conservation tillage technology small companionsoil by ploughing, few years plowing time for soil especially the newly reclaimed soil isa good.
The significance of land:
Mountain in the soil of repeated drying and freezing, the soil structure was improved
By breaking the harden layer, the soil permeability is improved
Cultivation to improve the ventilation of the soil, a easy microbial breeding
Rapid decomposition of a machine, increase the content of soil nutrients
The high wind also reduced herbicide, pesticide residues and a harmful chemical substances from residue of crop and weed
Root exudation
Tilling can also damage the environment for the survival of insect pests
In view of the above-mentioned points benefits, shall be carried out in the summerover suitable humidity conditions bu. Farming structure will destroy soil in smallhumidity conditions and leads to soil compaction.
