| 摘 要： | 试验结果表明，在肥料用量和补供水量均相同的情况下，膜侧谷子、地膜玉米的增产量大于膜侧冬小麦的增产效果；果树的增产效果大于粮食作物的增产效果。据此认为，适当压缩粮田面积，扩大果树面积，在粮食作物中压缩冬小麦播种面积，扩大谷子播种面积，是农田增效、农民增收的有效途径。

| Abstract: | The results of the experiment of fertilization and rainwater collecting in dryland showed that the same fertilizer level and the same amount of supplying water, the yield of millet cultivated at the side of film and film mulching corn increased more than winter wheat growing in the side of film, and the yield increase rate of fruit was higher than that of crops.So it is suggested that moderately reducing the area of crop and winter wheat and enlarging the area of fruit and millet can be an effective way to make higher income for farmers. |
