摘　　要：柑桔线虫病是江西省柑桔上的一种重要病害,发病重的病株率达100%,死株率达22.8%.经鉴定,主要致病线虫为柑桔穿刺根腐线虫(Pratylenchus penetrans).研究表明:砂壤土、pH5.8～7.4适宜线虫生长发育;土壤缺乏有机质,桔树长势差,降低其抗病性,发病严重;应用腐复肥加呋喃丹混合施用,防治效果最佳,有利于柑桔迅速恢复树势,并增强桔树抗病性和抗寒性,提高了产量与品质。The infection of nematodes in citrus is a major citrus disease in Jiangxi Province.Therate of the infected plants reached 100% in serious cases with 22.8% of the dead plant rate.The main species of pathogenic nematode was identified as Pratylenchus penetrans.As aresult of research,sandy soil and pH5.8～7.4 were indicated as the opimum for the growthof nematode,the shortage of organic matters in soil depressed the growth of the citrus andreduced its disease resistance and therefore worsened the disease condition;the use of hu-mus acid blended plus Carbofuran proved the best control effect,which benefited the citrusto regain its growth quickly,to strengthen its disease resistance and the cold resistance,in-creasing its output and bettering its quality.
