摘要:我市淮阴区丁集娘庄黄瓜根结线虫(Meloidogyne spp.)发生严重。本论文是在2014年的3月份开始,在娘庄黄瓜种植基地定点1号、3号、5号、7号、9号5个大棚,跟踪调查根结线虫病害发生情况。1号棚为未施生物农药对照,照常管理。其它四个棚10月份后定植浇灌宁盾(每棚10升),从2月初开始,每月调查一次,2次调查5个大棚中根结线虫数在施农药后的变化,结果显示未施药的1号大棚病害严重度从36%上升到40%,3号大棚在施农药后,病害严重度从34%上升到35%,5号大棚在施农药后,病害严重度保持在32%,7号大棚在施药后,病害严重度从29%上升到30%,9号大棚在施药后,病害严重度从24%上升到26%。4月15日-30日四次采收产量统计结果显示,对照1号棚的平均产量为401斤,9号棚的平均产量为441斤,表明该农药可有效防治根结线虫,使产量明显得到提高。57474

Abstract:Huaiyin district of Dingji Niangzhuang cucumber root knot nematodes (Meloidogyne spp.) serious. This thesis is in February of 2014, random in extract Niangzhuang 1, 3, 5, 7, 9 these 5 cucumber shed, tracking cucumber root knot nematode disease occurrence.1 tent did not administer, the other four tent to Ningdun(Each shed 10 liters), since early February, survey once a month, check two times five root knot nematodes in the greenhouses in pesticide after the change, the results of the survey for not administer 1 degree of greenhouses diseases increased from 27% to 40%, No.3 after four greenhouses with pesticide, disease degree increased from 32% to 34%, No.5 after four greenhouses with pesticide, disease severity stand at 32%, No.7 after four greenhouses with pesticide, disease degree increased from 29% to 30%, No.9 after four greenhouses with pesticide, disease degree increased from 24% to 26%, April 15-30 four harvest yield reference 1 tent an average of 401kg, 9 shed an average yield of 441 kg, show that the pesticide can effective prevention and control of root knot nematodes, the production was improved obviously.

黄瓜,又称青瓜,广泛分布于中国各地,是主要的温室产品之一。黄瓜喜温暖但不耐寒冷,产量高,需水量大,宜生活在含有机质的土壤中。近几年来,随着保护地种植面积的不断扩大,加上常年连作,黄瓜根结线虫病越来越严重,给生产带来了严重的损失。淮安市丁集黄瓜产业的发展, 是全市实现高效农业规模化的关键, 对促进农业增效、农民增收具有重要作用。本次我们选择了淮安市丁集镇娘庄村作为一地点,对此我们从2014年的两月份开始到五月份为止进行了为期三个月的的调查研究,初步了解了淮安地区的根结线虫病害。
