滇西北马铃薯不同栽培模式下产量及经济效益分析

Yield and Economic Benefit of Potato under the Different Cultivation Patterns in Northwest Yunnan

2014-2016年在云南丽江太安乡进行马铃薯平播后起垄、侧膜覆盖、覆膜覆土和大垄双行4种不同栽培模式比较试验,对马铃薯产量和经济效益进行分析,筛选适宜的马铃薯轻简高效抗旱栽培模式。3年试验结果表明侧膜覆盖平均产量最高,经济效益最大;从节省劳动力方面,平播后起垄是该区域最佳轻简高效抗旱栽培模式。

The experiment was conducted in Taian county of Lijiang city in Yunnan Province from 2014 to 2016 to compare the effects of ridge-furrow planting without plastic film mulching after flat planting （RFAF）, half mulching only on ridges （RFHM）, soil covering after plastic film mulching only on the ridges but not on furrows and no mulching on ridges and furrows on yield and economic benefit and select the best pattern of drought resistant cultivation. The results showed that the average yield and the economic benefit of RFHM was the highest in three years. The RFAF was the simple and labor saving cultivating techniques.
