摘要
为提高生产效率、降低生产成本,使宿根性多年生草本作物草莓(Fragaria×ananassa)能保持生长旺盛,达到一年种植多年收获,研究断根对上一年种植草莓母株生长的影响。结果表明,与未断根相比,断根能提高草莓植株的根系和茎叶生物量及根冠比,达到断根复壮的目的,在培土、断根对边1次、断根四周1次、断根四周2次及断根四周3次几种断根复壮方式中,断根四周3次提高根系生物量和根冠比较多、效果较好。
In order to improve production efficiency and reduce production cost,herbaceous perennial strawberry could be plantedone year and harvested for many years.The effect of root pruning on the growth of stock strawberry planted in the previous year was stu-ied.The results show that compared with no pruning roots,root pruning could increase the biomass of root system,shoot system androot-shoot ratio,and achieve the purpose of rejuvenation.Compared with different ways of ridging,root pruning opposite side once,root pruning all around once,root pruning all around twice and root pruning all around thrice,when root pruning all around thrice,thebiomass of root system and root-shoot ratio were higher than other treatments,which had a good effect.
