果树线虫病害调查和防治

１９８８－１９９３年在福建省主要果树栽培区调查果树线虫病。从果树根部和根际土壤中查出植物线虫２１属，其中根结线虫（Ｍｅｌｏｉｄｏｇｙｎｅ），根腐线虫（Ｐｒａｔｙｌｅｎｃｈｕｓ），穿孔线虫（Ｒａｄｏｐｈｏｌｕｓ），肾状线虫（Ｒｏｔｙｌｅｎｃｈｕｌｕｓ），剑线虫（Ｘｉｐｈｉｎｅｍａ），毛刺线虫（Ｔｒｉｃｈｏｄｏｒｕｓ）和拟毛刺线虫（Ｐａｒａｔｒｉｃｈｏｄｏｒｕｓ）对果树有一定为害。试验结果表明，利用抗线虫果树和砧木品种、改良土壤、施用杀线虫剂等措施能有效防治果树线虫病。

Investigation on Parasitic Nematodes of Fruit Trees and It's Control

Twenty-one genus of plant nematodes were identified from rhizosphere soil and roots of fruit trees in Fu-jian province.Meloidogyne、Pratylenchus、Radopholus、Rotylenchus、Xiphinema、Trichodorus、and Paratri-chodorus are important parasitic nematodes of fruit trees.Experimental results of control showed that para-sitic nematodes of fruit trees can be controlled by using rootstock and varieties which are resistant to nema-todes,soil reclamation and nematocids。
