分别以不施菌剂、不施腐植酸钾为对照,采用小区试验,探讨生防放线菌剂与腐植酸钾配施条件下二者对魔芋的防病促生作用。试验结果表明:(1)当腐植酸钾与3号放线菌配施时,具有较强的防病促生作用。30克/株、60克/株、90克/株腐植酸钾分别配施3号菌剂时,与不施腐植酸钾对照相比,魔芋病害相对防效、增产率及增长系数分别提高了9.8%~41.6%、17.1%~76.3%和20.1%~64.2%。其中,60克/株腐植酸钾配施3号菌剂时效果最明显。(2)当放线菌剂与腐植酸钾配施时,具有较强的防病促生作用。1、2、3号放线菌剂与60克/株腐植酸钾配施,与不施菌剂对照相比,魔芋病害相对防效、增产率及增长系数分别提高了11.7%~89.7%、33.3%~150.9%和38.5%~175.0%。其中2、3号放线菌剂与60克/株腐植酸钾配施处理效果较好。研究表明,腐植酸钾与放线菌剂配施能促进魔芋生长,提高魔芋产量,降低发病率。
The non-application of non-application of ferulic acid potassium as a control, the use of cell-based experiments to explore the biocontrol actinomycetes and potassium humate with the two conditions on the prevention and treatment of konjac effect. The results showed that: (1) When potassium humate was combined with actinomycete No. 3, it had a strong effect of preventing disease and promoting growth. 30 g / plant, 60 g / plant and 90 g / plant potassium humate, respectively. Compared with the control without applying potassium humic acid, the relative control effect, yield increase rate and growth coefficient of konjac disease increased 9.8% ~ 41.6%, 17.1% ~ 76.3% and 20.1% ~ 64.2%. Among them, the effect of 60g / plant potassium humate combined with No.3 agent was the most obvious. (2) When actinomycetes and potassium humate, when applied, has a strong role in disease prevention and promote growth. 1, 2 and 3 actinomycetes and 60 g / plant potassium humate were applied. Compared with the control, the relative control effect, yield increase rate and growth coefficient of konjac disease increased 11.7% ~ 89.7% 33.3% to 150.9% and 38.5% to 175.0%. Among them, No. 2 and No. 3 actinomycetes and 60 g / plant potassium humate combined treatment effect is better. Studies have shown that the combined application of potassium humate and actinomycetes can promote the growth of konjac, improve konjac yield and reduce the incidence.
