棉花枯、黄萎病已在新疆蔓延,构成了对新疆棉花生产的严重威胁。如何采取有效的综合措施进行防治,是摆在我们面前的紧迫任务。本刊对此作了多方面的反映,现在再将中国农科院土肥所刘庆城同志对施用液氨防治棉花枯、黄萎病的研究简况向读者介绍。据他所进行的盆栽和田间试验,用液氨施肥对防治棉花枯、黄萎病取得良好效果,值得重视。 液氨施肥,在新疆生产建设兵团开展了多年的示范试验和推广工作,而且得到了越来越多的生产单位的欢迎。目前,不论从推广的规模或经济效益来看,兵团都居于领先地位。我们应充分利用这一优势,把液氨施肥的推广和防治棉花枯、黄萎病的工作结合起来。在还不能较大面积推行液氨施肥的情况下,可先有目的地将一部分液氨施肥用在防治枯、黄萎病的试验上。我们希望有条件的单位都进行这一方面的试验,并将试验结果写成稿件寄给本刊编辑部,我们将根据需要予以选登。
Cotton withered, Verticillium wilt has spread in Xinjiang, constitutes a serious threat to cotton production in Xinjiang. How to take effective and comprehensive measures for prevention and control is an urgent task before us. This article made a multi-faceted response, and now again with the Chinese Academy of Agricultural Sciences, Comrade Liu Qingcheng soil fertilizer on the use of liquid ammonia prevention and control of cotton withered, Verticillium wilt to brief readers. According to his potted plants and field trials, the use of liquid ammonia fertilizers to control cotton withered, Verticillium wilt achieved good results, it is worth attention. Liquid ammonia fertilization, in Xinjiang Production and Construction Corps for many years to carry out demonstration experiments and promotion work, but also more and more production units are welcome. At present, both from the promotion of the scale or economic efficiency, Corps are living in a leading position. We should make full use of this advantage to combine the promotion of liquid ammonia fertilization with the prevention and control of cotton blight and verticillium wilt. In the case of large-area liquid ammonia fertilization can not be implemented, some liquid ammonia fertilizer can be purposefully used to test the control of withered and Verticillium wilt. We hope all the qualified units will carry out tests in this area and send the test results to the editorial department of this magazine. We will select them according to the needs.
