甘蔗套种马铃薯宽窄行栽培耕作模式及经济效益分析

Wide-narrow Spacing Interplanting of Potato with Sugarcane and Its Economic Effect

针对德宏州甘蔗套种马铃薯栽培中存在的技术措施参差不齐、经济效益不明显的生产实际问题,采用甘蔗套种马铃薯宽窄行栽培方式,分析其经济效益。结果表明,该套种模式下马铃薯小区产量随播种密度的加大而增加;套种马铃薯后甘蔗小区产量出现小幅度变化,但单位面积复合产值比净种条件下增加27.3%～50.7%。

Be aimed at the problem of uneven technology on interplant about potato with sugar cane in Dehong, economic benefit was not obvious. This study took the mode of wide-narrow spacing cultivation interplant about potato with sugar cane, the width of experiment plot was 2.0 meter, the length was 3.3 meter, the groove width of sugarcane was 0.8 meter, the moisture width of potato was 1.2 meter. There were 70 sugarcane buds, there were different density in potato plot. The results showed that, the yield of potato increased by adding density, the yield of sugarcane have slight change, however, the composite output in unit area increased by 27.3%-50.7%.
