贵州冬闲田马铃薯覆黑膜栽培模式研究

以早熟马铃薯品种费乌瑞它为材料,研究起垄黑膜覆盖栽培模式对冬马铃薯物候期、株高、叶面积及产量的影响效果。结果表明:与未覆膜对照相比,黑膜覆盖栽培模式可以提早出苗时间、现蕾期和成熟期,但对生育期影响不明显;对现蕾期株高、叶面积影响显著,叶面积可增加25.34%;对冬马铃薯的总产量及大薯产量影响极显著,总产量增产33.34%,大薯产量增产20.15%。该栽培模式是一种值得在西南地区冬闲田马铃薯生产中进行较大面积的示范推广的模式。

Study on Black Plastic Mulching Models of Potato Planted in Winter Fallow Land in Guizhou Province

The black plastic mulching techniques and traditional planting of potatoes without plastic coverage were studied on their effects to growth periods,plant height,leaf area and potato yield.The results showed that comparing with control,the main growth stages of the black plastic mulching model were earlier but growth period,and black plastic mulching model effected plant height,leaf area,total yield and large scale tuber yield significantly,especially leaf area,total yield and large scale tuber yield increasing with 25.34%,33.34% and 20.15%,respectively.And the black plastic mulching model should be recommended for demonstration,and popularized in the winter fallow land in Southwest area of china.
