摘　　要：为了科学有效防治根结线虫,采用室内与田间试验相结合的方法,研究移土法防治黄瓜根结线虫的效果以及对温室土壤养分和黄瓜生长发育的效应。结果表明,移土处理后第2年2月、3月、4月的防效分别为100%、80.5%和69.6%;危害高峰期和清园时间较对照区推迟30～40d,全生育期累计产量增加24.9%。0～20cm土壤养分含量有一定的降低,其中速效钾、速效磷、全氮和有机质含量分别较对照降低20.8%、61.9%、50.3%、63.4%。因此,在其他措施难以实施的地区,移土法不失为防治根结线虫的一项有效防治措施。In order to find an efficacy way against root-knot nematodes,shifting soil to control nematodes on cucumber and its effect on soil nutrient and cucumber’s growth were studied by laboratory and field trials.The results showed that the control effect was 100%,80.5%,and 69.6% in February,March and April of next year,respectively by shifting soil treatment.When the damage peak and clear up field’s period delayed 30-40 days,the cumulative yield of cucumber increased 24.9%,compared with CK.In soil of 0-20 cm depth,the content of available K,available P,tolal nitrogen and organic matter decreased 20.8%,61.9%,50.3%,and 63.4%,respectively compared with CK.As a result,shifting soil could be an efficacy method to control root-knot nematodes when other measures could not be applied in some areas.
