摘要
为提高辣椒抗病能力,减少化学农药用量、残留以及减轻环境污染,该研究采用测报调查、随机区组设计和统计分析等方法,开展了辣椒应用植物免疫诱抗剂5%氨基寡糖素AS田间药效试验。结果表明:在塑料温室大棚辣椒栽后3d、28d和幼果期施用3次,药后15、30、45和60d,抗病毒病效果氨基寡糖素750、1 000倍液与三十烷醇(对照药剂)1 000倍液分别为97.6%、69.0%、76.2%,94.1%、63.5%、72.9%,87.0%、63.9、72.2%和75.5%、49.1%、54.7%;抗煤烟病效果为84.6%、71.2%、73.1%,84.1%、70.5%、72.7%,80.8%、68.8%、69.7%和72.2%、53.7%、55.6%;疫病预防效果均为100%;可以有效促进辣椒营养生长、株高增高和分枝增多等,但辣椒产量、销售收入和纯收入,氨基寡糖素750、1 000倍液与三十烷醇1 000倍液每1hm2较清水对照(CK)分别低30.2%、13.3%和18.2%,21 505.92、9 453.18、12 995.55元及21 773.92、9 685.18、13 199.55元。产量清水对照(CK)极显著高于氨基寡糖素750、1 000倍液与三十烷醇1 000倍液,氨基寡糖素1 000倍液和三十烷醇1 000倍液极显著高于氨基寡糖素750倍液,氨基寡糖素1 000倍液与三十烷醇1 000倍液差异不显著。
In order to increase the disease resistance of pepper,decrease the chemical pesticides usage,residue andenvironmental pollution,themethods of forecasting,randomized block design and statistical analysis were used tothe field efficacy trials,which conducted of the disease resistance of pepper by using plant immune inducer- amino-oligosaccharin. The results showed that after applying dealt with 750 and 1 000 times liquid of 0.5% amino-oligosac-charin AS and dealt with 1 000 times liquid of triacontanol（drug control）3 days and 28 days after planting,andyoung fruit stage,the antiviral effects were 97.6%,69.0%,76.2%;94.1%,63.5%,72.9%;87.0%,63.9%,72.2%;and 75.5%,49.1%,54.7%,respectively,at 15,30,45 and 60 days after applying pesticide. The dark mil-dew control effects were 84.6%,71.2%,73.1%;84.1%,70.5%,72.7%;80.8%,68.8%,69.7%;and 72.2%,53.7%,55.6%,respectively,at 15,30,45 and 60 days after applying pesticide. As well as the phytophthora blightcontrol effects were all up to 100% after applying pesticide. These results manifested that the use of 0.5% amino-oli-gosaccharin AS could promote the nutrition growth and branch of pepper. Compared to the water control,the pepperyields of treated by dealt with 750 and 1 000 times liquid of 0.5% amino-oligosaccharin AS and drug control were30.2%,13.3%,and 18.2% lower,respectively. And the sales revenues and net incomes were reduced 21505.92,9453.18,12995.55 yuan and 21773.92,9685.18,13199.55 yuan. The yields of water control was significant higherthan that of three treatments;the yields of dealt with 1 000 times liquid of 0.5% amino-oligosaccharin AS and drugcontrol was significant higher than that of dealt with 750 times liquid of 0.5% amino-oligosaccharin AS;the yields ofdealt with 1 000 times liquid of 0.5% amino-oligosaccharin AS and that of drug control showed no difference.
