广西栽培的药用植物麦冬,多年来遭受根结线虫Meloidogyne sp.为害,有些地区损失较重。 为害麦冬的线虫种类不一,在各种麦冬上都普遍发生,数量很大。其中以根结线虫为害最重。据北流、荔浦等地取样分离检查,麦冬根内及栽培土壤中,都存在着大量的线虫。每丛麦冬的根围土壤中含有线虫可达11,925头;每亩麦冬以2—3万丛计,则每亩麦冬的根围土壤中将有线虫2—3亿头! 当然,这些线虫并非都为害麦冬,但寄
Ophiopogon japonicus, a medicinal plant cultivated in Guangxi, has been hit by Meloidogyne sp. For many years and suffered heavy losses in some areas. Radix Ophiopogon different types of insects, Ophiopogon in a variety of common occurrence, a large number. Among them, the root knot nematode is the most harmful. According to Beiliu, Lipu sampling isolation and other places, Ophiopogon roots and cultivated soil, there are a large number of nematodes. Each bundle of Ophiopogon in the rhizosphere soil contains up to 11,925 nematodes; Ophiopogon japonicus per hectare with 2-3 million units, then per mu of rhizosphere soil will have nematodes 2-3 million head! Of course, these Nematodes are not harmful Ophiopogon, but send
