Effect of Microbial Agent Trichoderma harzianum on Control of Sclerotinia sclerotiorum and Yield of Sunflowers
摘要
Abstract
In order to study the effect of microbial inoculant Trichoderma harzianum on the control of Sclerotinia sclerotiorum and yield of sunflowers,and to find the best control measures,a wettable powder of Trichoderma harzianum(Daimiao)was used as the test material.6 treatments of seed treatments and drip irrigation were applied to sunflowers in the field for prevention,including T1:100 g/500 g seed dressing+1 time 15000 g/hm2 drip irrigation,T2:100 g/500 g seed dressing+2 times 15000 g/hm2 drip irrigation,T3:100 g/500 g seed dressing+2 times 7500 g/hm2 drip irrigation,T4:100 g/500 g seed dressing+1 time 7500 g/hm2 drip irrigation,T5:1 time 7500 g/hm2 drip irrigation,and a blank control.The control effect of Sclerotinia on sunflowers and related traits were investigated at the mature stage of sunflowers.The results showed that the experimental areas using Trichoderma harzianum were improved to varying degrees in soil physical and chemical properties,main economic traits of sunflowers,yield and yield-related traits,and had obvious control effects on Sclerotinia of sunflowers.The best effect was achieved by seed dressing with Trichoderma harzianum and 2 times high-concentration drip irrigations,with a control effect of up to 74.37%and a yield of 1661.3 kg/hm2.The second-best effect was achieved by seed dressing with Trichoderma harzianum and 1 time drip irrigation,with a control effect of over 68%.Only 1 time drip irrigation achieved a control effect of 44.86%.关键词
