油菜菌核病是一种常发性病害,严重影响油菜产量和菜籽含油量。同时土壤缺硼对油菜结实的影响也日趋明显。为探讨防病与施硼肥的增产效果,我们于1989年进行了药肥混用防病增产的探索,在取得初步成功的基础上,1990年又进行了多菌灵硼砂配比试验,寻求最优配方,并进行了多点示范。现将结果报告如下: Sclerotinia sclerotiorum is a common disease that seriously affects rapeseed production and rapeseed oil content. At the same time boron deficiency on rapeseed solid effect has become increasingly evident. In order to explore the effect of disease prevention and yield increase of boron fertilizer, we carried out the exploration on preventing disease and increasing yield of medicinal fertilizer in 1989. On the basis of initial success, we conducted the test of ratio of carbendazim borax in 1990 to seek the most Excellent formula, and conducted a multi-point demonstration. The results reported below:
