The leaf WUE of millet was increased when root cutting in seedling stage,and only the treatment of I2D of maize increased the leaf WUE; The biomass WUE of millet and maize were increased excepting the root cutting treatments of "TM" and "sl"; At the 80% field capacity, when the root was cutted more seriously and more later,the seed yield WUE of millet were dropped; While at the 50% field capacity, the seed yield WUE of millet was increased when the root cutting is moderate in prophase,and have no reduction of output or increase the production at the same time ,while the benefit of saving water didnt evidently at the later stage root cutting.
苗期伤根处理能够提高谷子叶片WUE,而玉米伤根后仅I2D处理的单叶WUE高于对照;除TM和sl处理外,伤根处理提高了谷子和玉米生物量WUE;在土壤含水量为80%田间持水量时,随着伤根程度的加剧和伤根时间的后移,谷子子粒产量WUE下降,伤根不利于谷子WUE的提高;而在50%田间持水量时,前期伤根量适度的处理在不减产甚至增产的情况下还有助于作物子粒产量WUE的提高,而后期伤根的节水效果并不明显。

The experiments were carried out to calibrate FDR in the lab and field, and calibration equations were verified by oven-dried method for soil samples obtained by augers. The result showed that good calibrating equations with average RMSE 0.023 m^3/m^3 were fitted in the lab, but they had poor RMSE 0.066 m^3/m^3 when used in the field. Other calibrating equations with average RMSE 0.026 m^3/m^3 were also fitted by indirect field calibration method, and they had good RMSE 0.026 m^3/m^3 when used in the field.
