The result showed that the diurnal variation of temperature, irradiation intensity, net radiation as a curve in cotton canopy of two irrigation ways.
结果表明，在两种灌溉方式下棉花冠层内的温度、光照强度和净辐射日变化曲线均呈单峰线；
2
High salinity of irrigation water resulted in lower average water consumption intensity of wheat during the whole growing season, but higher water use efficiency.
灌水矿化度的增加降低了小麦在生育期的平均耗水强度，增加了小麦的水分利用效率。
3
The most important factor affecting the water supply amount is light intensity, the irrigation amount can be determined by the light intensity and the EC value of drain water from the substrate.
