【摘要】 室内实验研究结果表明,硫酸铝对水稻恶苗病菌菌丝生长具有较强的抑制作用,菌丝生长的EC50为0.070 3%,培养皿硫酸铝质量分数和菌丝生长的直线回归方程:y=-1.5+2.28x,r=0.92。田间试验结果表明,用质量分数0.5%~1.0%的硫酸铝水溶液浸种48 h,对水稻恶苗病具有85%以上的防治效果,而且对水稻生长安全无药害。更多还原

【Abstract】 The lab test results show that aluminium sulfate has a strong inhibition to the growth of fusarium moniliforme,the EC₅₀ of the bacteria is 0.070 3 %,the regressive equation between aluminium sulfate concentration and bacteria growth is as follows:y=-1.5+2.28x,r=0.92.The field test results show that when the feed is soacked with the solution of 0.5%¹.0%（weight） Al₂（SO₄）₃ for 48 h.,the prevention efficiency to fusarium moniliforme can be over 85% and it is no harm to the growth of the paddy.更多还原
