棉花枯黄萎病是由细菌引起的,在我国各大棉区普遍发生,是棉花生长中一大病害,而且发病率较高,很难控制,给棉花生产造成严重的损失,甚至绝收。为了探索有效地控制此病发生,我们应用唐山市全来生物工程公司生产的生化复合黄腐酸(以下简化为BCFA)喷施棉田,取得较好的效果,对棉花枯黄
Verticillium dahliae is caused by bacteria and occurs in every major cotton area in our country. It is a major disease in the cotton growing, and its incidence is high. It is hard to control and causes serious losses to the cotton production. In order to explore the effective control of the disease, we use Tangshan City to bio-engineering company biochemical composite fulvic acid (hereinafter simplified as BCFA) sprayed cotton fields, and achieved good results on the cotton yellow
