在此基础上，应用相对权重法计算土壤含水量、含盐量以及整地质量和播种方式等多个生态环境因子对出苗率的综合影响，进而确定播种量。
Sowing rate was then decided by integrating the effects of different soil water and salt contents, pH, temperature and sowing style on seedling emergence rate with relative weight method.
对于旱地小麦，利用可调翼铲式深松机深松后，可以增加播种前土壤含水量，改善播种质量，提高作物产量；
For dryland wheat, subsoiling operation could increase pre planting soil moisture, improve sowing quality and the yield could be increased by 10% compared with conventional tillage.
