由于不同农作物对于土壤养分、肥力等各方面的需求不同,而且不同区域的土壤也存在很大的差异,所以需要对农田土壤实施适当的改良措施,提高土壤的地力方式,提高土壤的农业性状,通过不断协调土壤中水、热、气、肥等各方面因素,提升土壤的综合指标,使土壤更利用农作物的生长和发育,并对农作物的高产起到有效的促进作用。 Because different crops have different demands on soil nutrients, fertility and so on, and the soils in different regions have great differences, it is necessary to carry out appropriate improvement measures on farmland soils, increase soil fertility and improve agricultural characteristics of soil, By constantly coordinating various factors such as water, heat, gas and fertilizer in the soil, we can enhance the comprehensive index of soil, make the soil make more use of the growth and development of crops, and effectively promote the high yield of crops.
