| 摘 要： | 该文研究了新农药单甲脒对植物－土壤系统的生态影响，结果认为：所设置的６个浓度（对照，２５％单甲脒水剂稀释１５００倍、１０００倍、８００倍、５００倍、１００倍）对棉花虫害有不同程度的防治效果，以１００倍最好，可防治棉花多种虫害。单甲脒对棉花种群的结构与功能无不良影响。高浓度单甲脒２２ ８００倍起至５００倍可使叶片气孔缩小，减少蒸腾速率，从而降低对水分的消耗，促进光合产物的形成，因而光合速率增长，生物

| Abstract: | his article has studied the ecological effect of new pesticite monocarboxoldehyde(DMAH)to the plant-soil system,The results show that the siw treated concentrations(CK.25%.DMAH diluted by 1500,1000,800.500,100 times)have different degress of preventionand control effect to cotton insect pest. The 100 times dilution is the best. which can preventmany kinds of cotton insect pest.DMAH has no bad effect on structure and function of thecotton population.The high concentraction DMAH(800 times to 500 times)can mak... |
