为探究3种杀菌剂高剂量处理的稻苗对水稻及取食褐飞虱种群的影响,南京农业大学植保学院、江苏省农科院植保所研究人员通过测定杀菌剂处理后稻苗体内草酸、还原糖以及可溶性蛋白的含量,并构建种群生命表探讨经杀菌剂处理的稻苗对取食褐飞虱种群生命参数的影响。结果表明,糯稻经己唑醇、噻呋酰胺、嘧菌酯等3种杀菌剂高剂量处理后,稻苗体内还原糖含量显著降低,碳氮比(C/N)有降低的趋势,草酸和可溶性蛋白的含量无显著变化。粳稻经3种杀菌剂高剂量处理后,C/N有升高的趋
In order to explore the effect of three kinds of high-dose fungicide-treated rice seedlings on the population of rice and their BPH populations, researchers at Plant Protection College of Nanjing Agricultural University and Plant Protection Institute of Jiangsu Academy of Agricultural Sciences determined that oxalic acid and reducing sugar And soluble protein content, and build life table of population to explore the influence of the germicide-treated rice seedlings on the life parameters of the BPH population. The results showed that the reducing sugar content of rice seedlings decreased significantly and the C / N ratio decreased with high dosages of hexaflumoxime, thifluzamide, azoxystrobin and other three fungicides. The contents of oxalic acid and Soluble protein content did not change significantly. After three kinds of fungicides were treated with high dose of japonica rice, C / N tended to increase
