为研究"新壮态"有机液体叶面肥与冲施肥在花生上的施用技术和应用效果,在山东莱西、辽宁阜新和江西赣州进行叶面肥试验,在阜新进行膜下滴灌模式下的冲施肥试验.结果表明,叶面肥试验,在赣州花生生育中期和前期(花针期与苗期)施用增产效果较好,莱西、阜新试验数据则分别显示在花生生育后期和中期(饱果期和花针期)、后期(饱果期)喷施增产效果较好;莱西试验产量最优处理饱果期叶面肥300X比空白对照蛋白质含量和油酸含量提高,含油量和亚油酸含量降低,更适合食用;在赣州调查,喷施"新壮态"叶面肥的花生植株叶斑病、锈病和白绢病发病较轻;膜下滴灌冲施肥试验,以饱果期浓度105L·hm-2产量最优;叶面肥试验和膜下滴灌冲施肥试验最优处理相比空白对照增产10%以上,净增收超过1950元·hm-2.
In order to evaluate the control effect of five fungicides on peanut early leaf spot disease caused by Cercospora arachidicola Hori,the inhibitory effects on mycelium growth,spore germination and control effect in the field of five fungicides were determined.Results indicated that carbendazim was the best among them with inhibitory rate of 91.4% on mycelium growth and 60.9% on spore germination.Prochloraz was also showed good inhibitory effect with 85.6% inhibitory rate on mycelium growth.No significant difference was found among other 3 fungicides(including cupric,Aike and tebuconazole).In field test,2 000mg/kg prochloraz was the best to control the disease with effect of 60.62% and increased the yield of 32.28% compared to water control.According to the indoor toxicity test and field control tests,prochloraz was the best fungicide among the five to control peanut early leaf spot disease.
