油菜菌核病和“花而不实”症是我地油菜减产的主要原因之一。为了减小这两个因素对油菜的危害程度,探索提高油菜单产的途径,今年,我们在汪桥办了30亩油菜花期施用“三合汤”的试验示范样板。所谓“三合汤”就是50%多菌灵、硼肥和尿素的混合液。试验表明,在油菜花期施用“三合汤”,增产效果较为显著,平均单产93.5公斤,比不施“三合汤”的田块多收43公斤多,增产46%。 Sclerotinia sclerotiorum and “blossoming” syndrome is one of the main reasons for the decrease in yield of rapeseed. In order to reduce the harm of these two factors to rapeseed and to explore ways to increase the yield of rapeseed, we conducted a pilot demonstration model of “Sanhe Tang” at the flowering stage of 30 mu rape at Wangqiao this year. The so-called “triple soup” is 50% carbendazim, boron and urea mixture. The results showed that the yield increase was more obvious with the application of “Sanhe Tang” during the rape stage. The average yield was 93.5 kg, more than 43 kg and 46% more yield than the plots without Sanhe Decoction.
