First, what is the straw-covered no-till straw-covered no-till method is a new type of farming method. Is a reform of the traditional farming method marked by a common type of plowing and tillage. The basic requirement is to reduce the agitation of the soil on the straw-covered ground to carry out mechanized direct sowing so as to maintain the original structure and level of the soil, No other topsoil will be carried out during this period. This tillage method to the soil without tillage, with straw mulch as the main feature. With energy-saving, labor-saving, increase production, to prevent soil erosion and other effects. It is different from rotary sowing, rake sowing, sowing stubble and other methods, production practices show that under appropriate conditions, the use of this mechanized non-tillage straight
