| 摘 要： | 对露地和网棚繁育的2个不同熟性马铃薯品种原种表现进行比较.结果表明.无论是网棚条件下繁育还是露地条件下繁育,对晚熟品种陇薯3号、早熟品种LK99的幼苗生长势、整齐度、生育期以及植株高度均没有显著影响.露地繁育的陇薯3号原种花叶病发病率比网棚繁育的高3.57～5.01个百分点,而繁育条件对卷叶病影响不显著.LK99无花叶病、卷叶病发生.2个品种晚疫病露地繁育的原种发病率均比网棚繁育的原种高5.0个百分点.生产的一级种网棚与露地相比.2个品种的单株块茎数、单株生产力差异均不明显.网棚繁育的陇薯3号比露地繁育的增产9.3%,LK99增产4.5%,增收不明显.差异不显著.种植一级种产量跟踪发现,生产的二级种网棚比露地减产幅度大.

| Abstract: | The comparsion was made for 2 a between production method of seed tuber, production in open field and greenhouse, in two potato varities, late-maturing variety Longshu No.3, and early-maturing variety LK99. The results shown that whether production in open field or in greenhouse there were no obvious differences between production methods in the growth-vigour and the seedling uniformity, the period of duration as well as the height of plant. The incidence rate of mosaic virus of Longshu No.3 virus-free pota... |
