淋洗作用

茶皂素对潮土重金属污染的淋洗修复作用

Leaching remediation of heavy metal contaminated fluvio-aquatic soil with tea-saponin

对于土壤初始含盐量高的新垦荒地，灌溉淋洗的作用要好于土壤盐分本底值低的土壤；

For the new cultivated wasteland with higher initial salt content , salt leaching results is better than the old farmland with lower salt content when the irrigation water is same .

土壤遭受到重金属污染后不但影响农作物的产量和品质，通过径流和淋洗等作用污染地表水和地下水，而且还可通过食物链等方式危害人类的健康。

The soil contaminated by heavy metals not only affects yield and quality of farm crops , pollutes the Earth 's surface water and groundwater , but also hurts human beings by food chain .

滴灌具有淋洗脱盐作用，即盐分积累到湿润锋附近，滴头下面土壤的含盐量相对较低。

Drip irrigation has the function of taking off salinity , which means that the soil salt content under the water dropper is relatively low as the salts tend to be accumulated at the wetted front .
