灌水量和水的盐度对玉米蒸散量及土壤含水量的影响

Effects of Irrigation and water salinity on maize evapotranspiration and soil water content

采用2017,2018,2019年的田间试验数据,研究了灌水量和水的含盐量对春玉米蒸散量和土壤含水量的影响。共设置9种灌溉处理,包括365,295,225 mm(O1,O2,O3)3个灌水量水平和0.65,3.2,6.1 dS·m^-1(Z1,Z2,Z3)的3个灌溉水盐度水平,采用交叉试验设计,每个处理重复3次试验,研究结果表明:实际蒸散量ETa随着灌水量的减少而减少。

Using field test data in 2017,2018 and 2019,the effects of Irrigation Water and water salinity on evapotranspiration and soil water content of spring maize were studied.A total of 9 irrigation treatments including 365,295,225 mm(O1,O2,O3)irrigation water levels and 0.65,3.2 and 6.1 dS·m-1(Z1,Z2,Z3)irrigation water salinity levels were used in the cross test design,the results showed that the actual evapotranspiration(ETa)decreased with the decrease of irrigation amount.
