虫砂复合微生物菌剂2种施用方式对棉花生长发育及防控黄萎病的影响
Effects of two application methods of insect-sand compound microbial agent on cotton growth and control of Verticillium wilt
摘要
Abstract
[Objective]In order to explore the green control technology of cotton Verticillium wilt,the effects of two different application methods on cotton growth and control of verticillium wilt under the synergis-tic effect of Protaetia brevitarsis worm dung-sand and microbial agents will be clarified,in the hope of provi-ding scheme reference for green control of the cotton disease and sustainable development of cotton industry.[Methods]Four treatments of larvae dung-sand combined with Bacillus subtilis(LD-KC),Bacillus amyloliquefaciens(LD-JDF),Trichoderma harzianum(LD-HC)and Zhongmian Junletu(LD-ZM)were set up,and total base fertilizer of the larvae dung-sand combined with microbial agents(TBF)and base fer-tilizer of larvae dung-sand+dressing microbial agents(BF+DBM)were used respectively.[Results]The growth and development indexes of cotton in BF+DBM group(plant height,stem diameter,first node of fruit branches,etc.)were better than those in TBF group,with LD-JDF and LD-ZM performing better.The yield increase of seed cotton in BF+DBM group was significantly higher than those in TBF group and control group(CK).The yield increase of seed cotton in BF+DBM group was 24.37％-33.40％.The highest yield increase was achieved in LD-JDF group(33.40％),followed by LD-HC(31.10％).In the early stage of Verticillium wilt,the disease index of TBF group was 3.80-5.85,the disease index of LD-JDF treatment was higher,reaching 44.36％,the disease index of BF+DBM group was 2.50-5.33,the disease index of LD-HC treatment was the lowest,and the prevention effect was 63.40％.In the late stage of Verticillium wilt,the disease indexes of TBF group and BF+DBM group were between 27.00-31.67 and 21.67-30.83,respectively,and JDF had the highest control effect,reaching 19.00％and 34.98％respectively.[Conclusion]During the whole growth period of cotton,the basic application of larvae dung-sand combined with semi-quantitative biocontrol bacteria plus semi-quantitative biocontrol bacteria topdressing can effec-tively promote the growth and development of cotton,and has a good control effect on cotton Verticillium wilt,and the effect of increasing production is more obvious.LD-JDF has the best effect of increasing production,and base fertilizer of larvae dung-sand+dressing biocontrol microorganisms.关键词
