摘要
以设施大棚黄瓜为试材,在设施大棚经过土壤熏蒸后,分别设定未添加商品化微生物菌剂、添加商品化微生物菌剂、添加棘孢木霉、添加产紫篮状菌(Talaromyces purepurogenus)Q2菌株4 个处理,通过测定黄瓜生长势、叶绿素含量、根系活力、光合作用及防御酶活性,研究了土壤熏蒸后添加产紫篮状菌Q2菌株对黄瓜植株生长的影响.结果表明,产紫篮状菌Q2 菌株可通过改善黄瓜根系活力和光合作用促进黄瓜植株的生长,产紫篮状菌Q2菌株处理的黄瓜植株功能叶光合速率提升了8.72%、叶绿素含量提高了20.79%、茎粗增加了11.26%、根系活力提升了30.00%以上,植物苯丙氨酸解氨酶活性(PAL)和过氧化物酶活性(POD)也显著上升.综合可知,土壤熏蒸后添加产紫篮状菌Q2菌株能够有效促进黄瓜生长,为菌株Q2开发利用提供理论支撑.
Abstract
Cucumber in the greenhouse was used as the test material.After soil fumigation in the greenhouse,four treatments were set,inclu-ding no commercial microbial agent,commercial microbial agent,Trichoderma asperellum and Talaromyces purpureogenus Q2 was added.By measuring the cucumber growth potential,chlorophyll content,root activity,photosynthesis and defense enzyme activity,the effects of adding strain Q2 on the growth of cucumber after soil fumigation were studied.The research results indicate that strain Q2 can promote the growth of cucumber plants by improving root activity and photosynthesis.The photosynthetic rate,chlorophyll content,stem diameter,and root activity of cucumber plants treated with strain Q2 increased by 8.72%,20.79%,11.26%,and more than 30.00%,respectively.The activity of phenylal-anine ammonia lyase(PAL)and peroxidase(POD)in plants also significantly increased in the treatment of strain Q2.In conclusion,the ad-dition of strain Q2 after soil fumigation could effectively promote the growth of cucumber,which provided theoretical support for the develop-ment and utilization of strain Q2.
