棉隆熏蒸和噻唑膦穴施对马铃薯孢囊线虫的防效及对马铃薯产量的影响
Impact of Dazomet Fumigation and Fosthiazate Hole Application on Potato Cyst Nematode Infestation and Potato Yield
摘要
Abstract
To prevent and control the spread of potato cyst nematode,a research on field control methods for this pest was carried out.In the experiment,dazomet fumigation and fosthiazate hole application were adopted.The effects of these measures on potato production were analyzed through various indicators,such as the SPAD value and nitrogen content of the leaves,plant height,plant weight,yield at maturity,and the number of potato cyst nematodes at the pre-sowing,flowering,and maturity stages of the potatoes,and the control effect of potato cyst nematode.The results revealed that both of the treatments significantly improved the plant height and enhanced photosynthesis of leaves.At the same time,the control measures reduced the infection of potato roots by cyst nematode.The average control efficacy of dazomet fumigation for potato new cysts nematode was 91.07%,which was significantly higher than that of fosthiazate hole application and control treatment.Compared with the control,dazomet fumigation and fosthiazate hole application increased the average yield by 20.13%and 9.69%,respectively.Dazomet fumigation was notably more effective in suppressing the potato's infection of potato cyst nematode than fosthiazate hole application,and it also substantially increased the rate of big tuber and potato yield.关键词
