摘要
为研究陇东旱塬区冬油菜收获后复种马铃薯不同栽培模式对其产量及经济效益的影响,采用单因素试验区组设计,以陇薯 7 号原种马铃薯品种为试验材料,共设计 8 种栽培模式.通过对不同模式下马铃薯农艺性状、商品率、产量及经济效益的比较,筛选出最佳的冬油菜茬复种马铃薯栽培模式.结果表明,秸秆带状覆盖、平作起垄、垄沟种植 3 个栽培模式表现较好,667 m2 产量分别为 2 292.81、1 917.63、1 655.46 kg,比对照露地平作分别增产41.27%、18.15%和 2.00%.
Abstract
In order to study the effects of different cultivation modes on yield and economic benefits of potato production after winter rapeseed harvest in the Loess Plateau of eastern Gansu province,a single factor experimental area design was adopted in this experiment.The original potato seed variety Longshu No.7 was used as experimental material,and a total of 8 cultivation modes were designed.They are plain cropping,plain cropping and ridge raising,high ridge black film mulching,high ridge white film mulching,high ridge black film mulching,high ridge white film cover soil,high ridge white film cover soil,straw strip mulching and ridge furrow rain collection.Through the comparision of potato agronomic characters,commodity rate,yield and economic benefits under different patterns,the best cultivation mode of winter rape stubble multiple planting potato was selected.The results showed that the three cultivation modes of straw strip mulching,flat planting and ridge and furrow planting were better,and the yield of 667 m2 was 2 292.81,1 917.63 and 1 655.46 kg,respectively,which increased 41.27%,18.15%and 2.00%compared with the control(plain cropping),respectively.
