盐碱地种稻泡田冲洗定额及灌水方法

Leaching Quota on Steeping Field for Transplanting Rice and Irrigation Method of Growing Rice in Saline-alkali Land

盐碱地的水稻一生都要不同程度地受盐碱危害,但其不同生育期对盐害的敏感程度是不同的,在幼苗期耐盐能力最弱。因此,要选择适宜的泡田冲洗定额和冲洗方法,以控制根层土壤含盐量<0.001 5,确保稻苗正常生长发育。

Growing rice saline-alkali land suffers from saline and alkali in growing period, but degree of sensitivity is different to harm of salt at different growth stages of rice, and ability of salt tolerance is the feeblest at seedling stage. So we will choose befittingly flushing quota and flushing method on steeping field for transplanting rice in order to control that content of salt in the middle of root soil is less than 0. 000 15, and ensure seedling of rice to grow normally.
