在苗圃内寄生着多种线虫。其中危害最大的有短体属(Pratylenchus)Penetrans 线虫、短体属 Vulnus 线虫和根结属线虫(Moloidogyne Spp.)及 Criconemella(Macroposthonia Xenoplax).这些线虫都不同程度的危害果树和根系,使其植株生长势哀弱.这类寄生在植株上的线虫很容易借助人们的疏忽进行传播和繁殖.外寄生线虫:这类线虫是用口针吸取植株的根汁为食,只寄生在植株根的外部.这类线虫对植株的危害主要是进行大量的群体繁殖,导致根哀弱,寄生在桃砧木上的 Criconemella Xenoplax 线虫就
In the nursery parasitic with a variety of nematodes. Among them, the most harmful species are the Pratylenchus Penetrans nematodes, the short-borne Vulnus nematodes and the Moloidogyne spp. And the Criconemella (Macroposthonia Xenoplax). These nematodes all have different degrees of damage to the fruit trees and roots, Growth potential is weak .This parasitic on the plant nematodes can easily spread by people’s negligence and propagation.Exesite nematodes: these nematodes is to use the needle to absorb the root juice of plants for food, only parasitic on the outside of the plant roots . The nematode harm to plants is mainly the result of large numbers of herd multiparities that lead to the weaker roots that infest Criconemella Xenoplax
