摘要
为贵州春旱频发地区薏苡高效种植提供依据,采用田间试验方法比较了7种栽种方式的薏苡产量与收益差异。结果表明,采取垄作+覆膜+膜侧直播、垄作+覆膜+膜侧育苗移栽、垄作+覆膜+膜内育苗移栽和垄作+育苗移栽4种栽种方式均比传统的平作+直播(CK)方式增产增效,分别增产10.3%、19.2%、18.3%和12.1%,净增收益8.9%、12.7%、12.3%和10.8%,均可作为春旱地区薏苡栽种的适宜方式。
In order to provide a reference for efficient cultivation of C.lachryrma-jobi in Guizhou spring arid area,a field experiment was conducted to compare the yield and benefit difference of seven cultivation patterns.Results：There were four models significantly better than CK in both yield and efficiency,which were “making ridge ＋ covering film ＋ transplanting seedlings with nutritional carrier beside film”,“making ridge ＋ covering film ＋ transplanting seedlings with nutritional carrier inside film”,“making ridge ＋ uncovering film ＋ transplanting seedlings with nutritional carrier”,and“making ridge ＋ covering film＋ direct sowing beside film”.Their yield increased by respectively 10.3%,19.2%, 18.3% and 12.1%,and the benefits increased by 8.9%,12.7%,12.3% and 10.8%.Therefore they were suitable for planting C.lachryrma-jobi in Guizhou spring arid area.
