复合微生物菌剂在魔芋栽培中的应用

Application effect of compound microbial agent in Amorphophallus konjac cultivation

为验证复合微生物菌剂在大田栽培中的应用效果,以魔芋(Amorphophallus konjac)为试验对象,设置复合微生物菌剂、化学药剂、清水3个处理,测定魔芋生长、病害发生及产量指标。结果表明,复合微生物菌剂可促进魔芋茎叶及根系生长,增加根系活力,降低病害发生,提高球茎鲜重、促进球茎膨大以及增加产量;轮换施用的3种化学药剂,12%中生菌素1000倍稀释液、20%噻菌铜500倍稀释液、20%噻唑锌500倍稀释液可较好地控制病害发生,提高魔芋单位面积产量但影响根系生长,降低根系活力。

In order to verify the application effect of compound microbial inoculants in field cultivation,Amorphophallus konjac was used as the test object,and three treatments of compound microbial inoculants,chemical agents and clear water were set up to determine the growth,disease occurrence and yield indexes of Amorphophallus konjac.The results showed that compound microbial inoculants could promote the growth of stems,leaves and roots,increase root activity,reduce disease incidence,increase bulb fresh weight,promote bulb expansion and increase yield.Three chemical agents,12% Zhongshengmycin 1000 times dilution,20% Thiodiazole copper 500 times dilution and 20% Thiazole zinc 500 times dilution,which were applied alternately,which could better control the occurrence of diseases,increase the yield per unit area of Amorphophallus konjac,but affect root growth and reduce root activity.
