摘 要:宁南县应用等高固氮植物篱间作甘蔗模式的试验结果表明 ,金沙江干热河谷坡耕地上沿等高线每隔 6 m培植固氮植物篱 2年后 ,在植物篱之间的作物种植带上种植地膜甘蔗 ,种植期浇灌 l次 ,单位面积产量 12 8t/hm2 ,产值 2 5 6 0 0元 /hm2 ,比传统旱坡地甘蔗分别高 70 .6 7%、 74 .86 % ,甘蔗种植期用水量比传统旱坡地甘蔗下降 2 1.31% ,节约用水 2 14 5 m3 /hm2 。Experiment of contour hedgerow sugarcane intercropping has been carried out to assess its appropriateness in dry and hot valley of the Jinsha River. The results suggest that production of sugarcane intercropped in the contour hedgerow system under plastic film cultivation can be increased by 70.67%, and farmers' cash income can be increased by 74.86%, respectively, over that of sugarcane under traditional plastic film cultivation on the same land. Hedgerow sugarcane intercropping can also save water 2 145 cubic meter per hectare, which implies great suitability and potential of the intercropping system in development of water saving agriculture in dry valley region.
