摘要
运用田间小区试验方法,在豫东平原砂壤土生态类型区麦田,初步探讨了杀菌剂对强筋小麦产量及品质的影响。试验结果表明,使用三唑酮、多菌灵、灭菌丹、烯唑醇及病虫灵等5种杀菌剂,强筋小麦千粒重提高0.8～1.9g,产量增加147.6～471.3kg/hm2,平均增产5.4%。于小麦抽穗后喷洒1次杀菌剂效果较好,增加喷洒次数以后对强筋小麦品质有不良影响。不同生育期应用杀菌剂,基本上不影响强筋小麦的品质,其应用效果主要取决于杀菌剂种类及喷洒次数。既使强筋小麦增产,又基本不影响其品质指标的杀菌剂为三唑酮和烯唑醇,其中又以三唑酮的增产效应最为突出,一般增产8%以上,千粒重提高2g左右,生产中可以考虑优先选用。
Using field experimentation, we initially study that fungicides influence wheat＇s yield and quality on sandy loam ecotype farm in the east of Henan. The result showed that using five kinds of fungicides such as triadimefon, carbendazim, folpet, diniconarole, and Bingchong ling and so on. These raised the weight of every one thousand seeds 0.8～1.9g of stronger gluten wheat, The yield increases 147.6～471.3kg/hm^2.The average increase in production is 5.4%. The effect is better to spray fungicides once when wheat lifts its head, but the quality will suffer from bad influence when we increase spraying times. Fungicides were used in the different wheat-bearing time ,however they seldom impair the quality. Its applied effect mainly depends on the types and spraying times of fungicides. Not only can triadimefon and diniconazole raise stronger gluten wheat＇s yield, but also don＇t impair its quality .Furthermore the increasing effect of triadimefon is the most obvious . Generally,it can raise above 8% and increase the weight of every one thousand seeds about 2g, so we can have a priority to choose it in production.
