以库尔勒包头湖农场膜下滴灌棉田为研究对象,选取3种不同盐度棉田土壤,通过对棉田整个生育期土壤水分和盐分含量的测定,对不同盐分棉田膜下滴灌各生育时期及各土壤层水盐分布的影响进行了研究。结果表明,含盐量较高的棉田土壤平均含水率较高且变化趋势较平缓;3种盐分土壤整个生育期含盐量变化趋势相同但含盐量较高的土壤变化幅度较大。
Taking the drip irrigation under cotton field in Baotou Lake farm of Korla as the research object, three kinds of soils with different salinities were selected. Through the determination of soil moisture and salt content in cotton field during the whole growth period, The effects of water and salt distribution were studied. The results showed that the average soil moisture content of cotton fields with higher salt content was higher and the change trend was more gentle. The soil salinity varied with the same growth rate but higher with higher salt content in the three salinity soils.
