宁夏引黄灌区农田退水回灌对土壤盐分影响的试验研究
Effects of Salinity Changes upon Farmland Return Flow Reusing in Ningxia Yellow River Water Irrigation District
摘要
Abstract
Throughout the whole growth period of wheat, setting four different irrigation settles under the same irrigation quota condition, comparing and analyzing the effect of soil salinity upon farmland return flow reusing, and analyzing the wheat output, the result showed: farmland return flow reusing would increase the soil salinity at 0 to 40 cm, especially had more effect on the soil at 0 to 20 cm. And the influence will decrease with depth increased. During the period of jointing and filling, using the farmland return flow to irrigate continually will cause the spring wheat output dropped, only irrigated with farmland return flow at the period of jointing will increase spring wheat output.关键词
