不同耕地类型菊芋种植模式对比研究

以"青芋1号"菊芋为供试品种,对不同耕地类型菊芋种植模式进行了对比研究。结果表明,山旱地菊芋生长量仅为水浇地的1/2;宽窄行配置方式对生育前期菊芋茎、叶生长发育有一定促进作用,但未显示对块茎的增产效应;山旱地垄沟种植有利于促进茎、叶生长发育和块茎的膨大,增产效应显著。水浇地起垄种植有利于茎、叶生长发育和块茎的形成,增产效应显著。建议在山旱地适当提高种植密度以及采用垄沟种植,水浇地采用起垄种植。

Contrast Study on Different Land Type and Planting Patterns in Jerusalem artichoke

Contrast study on planting patterns of Jerusalem artichoke in different land types was conducted by using Jerusalem artichoke ＂Qingyu 1＂ as trial material.It shows that growth increment of Jerusalem artichoke on mountain dry land is just half as much as that on irrigation land;collocation pattern of width-narrow row has some contribution to the growth and development of stems and leaves in Jerusalem artichoke,but has on effects on tuber yield;furrow cultivation on mountain dry land is helpful to not only the growth and development of stems and leaves but tuber bulking and has significant effects on yield increasing;so does ridge cultivation on irrigation land except it helps tuber forming,not bulking.It is suggested that planting density should be increased and furrow cultivation should be used on mountain dry land,while ridge cultivation be used on irrigation land.
