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。 The experiment was carried out to compare the effects of improving the crop rhizosphere soil moisture and the growth and development of spring maize with the measures of collecting rain cover. The results show that rainfall accumulation can effectively accumulate natural rainfall, especially for ineffective and sub-optimal rainfall of ≤10 mm, which can improve crop rhizosphere soil moisture, increase temperature and increase yield.
