我省有相当大一部分低产稻田是由于土壤水分过多,通气条件差,土壤冷烂、有效养分含量低;还有部分水田在绿肥压青后,土壤有毒物质增加,阻碍作物根系生长发育,水稻产量低。为此,我们于1990～1991年进行了以通气增温、协调土壤水、气矛盾为主要目的的水稻微沟通气栽培方法的田间试验。 A large part of low-yielding paddy fields in our province are due to excessive soil moisture, poor aeration conditions, cold and rotten soil, and low effective nutrient contents. In some paddy fields, green soil fertilizers increase soil toxic materials and impede crop root growth and development. Low Yield. To this end, we conducted field experiments on the cultivation of rice micro-gully ventilation with the main purpose of aeration and warming, coordination of soil water and gas contradiction in 1990-1991.
