摘    要:探讨了秋收后玉米地灭茬、灭茬后覆膜、留茬等不同处理方式对春播前土壤含水量的影响;测定结果表明,各处理春播前田间的表层土壤水分含量为覆膜>灭茬>留茬,且覆膜和灭茬处理的土壤含水量随时间延长变化较小,而留茬处理的土壤含水量随时间延长下降明显。

关 键 词:土壤含水量  灭茬  留茬  覆膜

Abstract:The effect of different farming treatments with cornfields after autumn on soil moisture before spring sowing was discussed.The results indicated that before the spring sowing,the soil moisture of surface layer with each treatment was in a decreasing order of film-mulching after stubble breaking,stubble remaining.And the change of soil moisture with the treatments of breaking was less with time increasing,but the change of soil moisture with the treatments of stubble remaining was obvious with time expand.
Keywords:soil moisture  stubble planning  stubble remaining  film-mulching
