2011年6~8月进行2期池栽试验,研究土壤水分及农艺措施对夏玉米出苗及幼苗生长效应。结果表明,播种后镇压覆盖能够提高土壤含水量,平衡土壤温度,从而提高夏玉米出苗率,增强幼苗素质,提高苗期田间株高整齐度,有利于培育齐苗壮苗,在土壤水分不太充足时效果更为明显。为保证黄淮海夏玉米区的出苗质量,播种时的土壤最低持水量应保持土壤最大持水量的60%。
2011年6~8月進行2期池栽試驗,研究土壤水分及農藝措施對夏玉米齣苗及幼苗生長效應。結果錶明,播種後鎮壓覆蓋能夠提高土壤含水量,平衡土壤溫度,從而提高夏玉米齣苗率,增彊幼苗素質,提高苗期田間株高整齊度,有利于培育齊苗壯苗,在土壤水分不太充足時效果更為明顯。為保證黃淮海夏玉米區的齣苗質量,播種時的土壤最低持水量應保持土壤最大持水量的60%。

The effects of soil water and agronomic measures on eco-physiological responses of no-tillage seedling summer maize were explored from June to August in 2011. The results showed that the compaction and wheat straw mulching after sowing was not only propitious for increasing soil moisture content, but also beneficial to balancing and improving the status of soil temperature through the function of heat preservation. For ensuring high quality summer maize seedlings in Huang-Huai-Hai plain, the soil water should be higher than 60% of field moisture capacity at sowing time.
