摘要
以常规小畦平播为对照 ,探讨了春玉米采取集雨覆盖措施后对改善作物根际土壤水分及春玉米生长发育的影响。结果表明 ,集雨覆盖后能够有效地集蓄自然降雨 ,特别是对于≤ 1 0 mm的无效和微效降雨 ,起到改善作物根际土壤水分状况、增温、增产效果。
With conventional cultivation model as comparison,the effects of water collecting mulch on improving root zone soil moisture and on growth and development in spring maize were investigated with field experiments conducted in Jinzhong Plain, Shanxi Province. Results showed that water collecting mulch is useful to collect rain water and to improve soil moisture of root zone in spring maize. Water collecting mulch is also useful to raise soil temperature and yield.
