针对青霉菌灭活菌丝体制剂示范推广中出现不同土壤环境中效果存在较大差异的问题,开展砂土和壤土中青霉菌灭活菌丝体制剂对烤烟抗逆能力的影响试验。结果显示,青霉菌灭活菌丝体制剂的效果在不同质地的土壤中差异明显。砂土中施用青霉菌灭活菌丝体制剂15 kg/hm2的效果优于施用7.5 kg/hm2;前者的主要农艺性状显著高于常规防治和空白对照,未出现黑胫病病株,对烟草花叶病的相对防效达81.88%,比对照增产180 kg/hm2、增值8 400元/hm2。壤土中施用青霉菌灭活菌丝体制剂15kg/hm2的效果比施用7.5 kg/hm2的效果略差;后者的主要农艺性状显著高于常规防治和空白对照,未发现黑胫病和根黑腐病病株,对普通花叶病的相对防效达74.60%,比对照增产255 kg/hm2、增值11 707.5元/hm2。
Aiming at the problem of different effects on soil environment in demonstration and popularization of Penicillium mycelium intimidating mycelium, the influence of Penicillium mycelium in sandy soil and loamy soil on the resilience of flue-cured tobacco was tested. The results showed that the effect of Penicillium mycelium inactivation in different soil texture significantly different. The results showed that the main agronomic traits of the former were higher than those of the control and blank control, and no black shank diseased plants were found in the soil with 15 kg / hm2 inactivated mycobacterium. Mosaic disease 81.88% relative control, yield 180 kg / hm2 than the control, the value of 8 400 yuan / hm2. The effect of Penicillium mycelium inoculation mycelium preparation 15kg / hm2 was slightly worse than that of 7.5kg / hm2 application in loamy soil. The main agronomic traits of the latter were significantly higher than those of conventional control and blank control. No black shank and root black The relative control effect on common mosaic disease was 74.60%, which was 255 kg / hm2 more than the control and the added value was 11 707.5 yuan / hm2.
