棉隆处理土壤防治黄瓜枯萎病的效果及效益分析

用棉隆处理大棚土壤防治黄瓜枯萎病，防效可达２７．８２％～８２．０３％，亩净增经济效益２５４．８～３０５．１４元。土壤含菌量较低和第２年连续进行土壤处理的地块，防效虽然也很明显，但经济效益显著降低。建议在黄瓜枯萎病严重的地块和没有备好嫁接苗的情况下选择采用。

The Effect and Economic Benefit Analysis of the Soil Treated by Dazomet against Fusarium Wilt of Cucumber (Fusarium oxysporium f. sp. cucumerium)

The paper dealt with the soil treatment of dazomet against fusarium wilt of cucumber (Fusarium oxysporium f. spcucumerium) in plastic house. The result showed that control effect was ranged from 27. 82% to 82. 03% and economic benifit was 254. 80 to 305. 14 Yuan(RMB) per mu. In the soil where eontains few microbes or where applies dazomet to soil treatment for successively two years, the control effect Was good but the economic benefit was evident decreased. We proposed dazcmet should be applied to heavily infected field or applied when grafting seedling is not ready for transplanting.
