Abstract
Covering farming techniques is an effective means of protecting and managing soils in arid, semi-arid and sub-humid and drought-prone areas, and is a change to traditional farming systems. This technology can regulate the “water, fertilizer, gas, heat” of farmland soil, change the physical and chemical properties and environmental quality of soil in arid areas, and effectively solve a series of problems caused by drought and irrational farming. Through different farming cover measures, In order to achieve stable production and high yield, it has important promotion value in the loess area. Through comprehensive research on the relevant research and demonstration experience of predecessors, this paper deeply studies the growth and development of spring maize and soil water and fertilizer effects under different cropping practices. It is found that different coverage measures have significant gain effects on soil moisture and fertility. The increase in corn production has a positive effect.
