在深水田应用半旱式免耕耕作法,比其他耕作法显著增产。通过1988—1989年两年的试验,亩增产量和增产率分别为35.9—60.0公斤和61.6—175.4％(1988)、9.4—28.7公斤和7.9—29.0％(1989)。比较各种耕作方法,半旱式免耕耕作法能保持良好的土体结构,具有排渍、升温、透气和培肥的改土效果,土壤的水肥气热协调。
The application of semi-arid no-till cultivation in deep-field fields increased significantly compared with other tillage methods. Through the two-year trial of 1988-1989, the yield increase and yield increase were 35.9-60.0 kg and 61.6-175.4% (1988), 9.4-28.7 kg and 7.9-29.0% respectively (1989). Compared with different tillage methods, the semi-arid no-till tillage method can maintain good soil structure, with soil improvement effect of drainage, heating, ventilation and fertilizing, and coordination of water, fertilizer and gas in the soil.
