摘  要：
[目的]为提高辽西北旱农区春播土壤含水量,充分利用有限土壤墒情,进行玉米播种部位浸种出苗试验研究。[方法]通过采用浸种与不浸种,及单穴增墒6个处理,分别于播种前、出苗期测定土壤含水量。[结果]玉米浸种处理在不同单穴加水量7 d内的土壤水分依加水量的增加而呈上升趋势,未经浸种玉米虽在播种部位土壤含水量也与单穴增墒剂量呈正相关,但出苗期比浸种处理延迟11 d,浸种出苗率达到43.6%,未浸种的处理出苗率仅27%。[结论]玉米浸种处理可有效提高出苗率及出苗时间,为玉米增产技术保障。

摘  要：
[Objective] The aim was to increase the soil water content and make full use of soil condition during spring sowing in northwest dryland farming area of Liaoning. The soaking maize seedling was studied.[Method] With soaking or not and 6 soil moisture different treatments, the soil water content was measured before sowing and seedling. [Result] The soil water content showed increasing tendency with different water added in single hole. The date of no soaking maize delayed 11 days, although the soil water content and water in single hole were positive correlated. The rate of germination were 43.6% and 27% respectively. [Conclusion]The maize soaking seed could increase the rate of germination and time, which would provide technology safeguard for maize yielding.
