| 摘 要： | 在半干旱偏旱地区采用微集水种植技术可使作物产量增加 ,水分利用效率提高 ,特别是当季降雨的水分利用效率提高 ,而经济效益则在不同作物间存在较大差异。 2年定位试验结果表明 ,生育期长、生产潜力大的作物产量增幅较大 ,且在产量增加的同时提高了农户的经济收益 ;5种作物产量增幅依次为玉米 >谷子 >小麦 >豌豆 >糜子 ,玉米为首选种植的作物 ,糜子、豌豆则不宜采用该方法种植

| Abstract: | In arid and semi-arid areas, the planting technique of micro-water harvesting can increase yields of crops and water using efficiency(WUE), especially for WUE of the planting season rainfall. The economic benefit has great difference among five crops. The results of two years oriented experiments show that crops of long growing time and great potential production have high yield raising, and farmers gain more income. The yield increase of five crops is: corn>m illet> spring wheat>pea>panic.Corn is the priority of planting crop, but this technique can't be applied to panic and pea. |
