| 摘 要： | 以垦单7号为试材,从玉米根际土壤中筛选链霉菌株SF-1,通过测定其活性,研究其代谢产物不同剂量及与其它生物药剂混剂对玉米丝黑穗病田间防治效果,确定其最佳用量、对玉米的安全性和产量的影响.结果表明:生防制剂可提高玉米出苗率,其中SF-1 20倍液+BYM对玉米丝黑穗的防治效果较好,为69.55%,增产效果也比较明显,为1...

| Abstract: | Streptomyces SF-1 was screened from maize rhizosphere soil.The metabolic product of application SF-1 with different dose and mixed with other biological microbial agent to prevent maize head smut in the field were studied by determining Streptomyces activity to confirm the optimum dosage and the effect on yield and safety of maize.The results showed that biological microbial agent could promote emergence rate of maize,SF-1 20 times liquid＋BYM had excellent control effect on maize head smut for 69.55%,and the maize yield increased notably by 13.69%. |
