棉花角斑病是一种细菌性病害,新疆各棉区发生都很普遍.这种细菌主要在棉籽上,特别是棉籽短绒上越冬.因此,消灭种子表面的细菌,是防治角斑病的有效途径.近年来,新疆各地逐步推广硫酸脱绒,兵团各农场已全面推广.因硫酸有很强的吸水作用,短绒、种皮所含的水分被吸收,放出大量热能,温度可高达60℃.在这样高温下,加上硫酸的吸水、腐蚀,细菌被杀死而消灭.实践证明,硫酸脱短绒消灭角斑病的效果,比其他药剂拌种、闷种、浸种更确实而可靠,很受群
Cotton leaf spot disease is a bacterial disease, occurring in every cotton area of Xinjiang, which is mainly on winter cottonseed, especially on cottonseed linter. Therefore, to eliminate bacteria on the surface of seed is to control angular leaf spot Effective way.In recent years, Xinjiang gradually promote the sulfuric acid velvet, the Corps farms have been fully promoted.Sulfuric acid has a strong water absorption, linter, the moisture contained in the seed coat is absorbed, release a lot of heat, the temperature can be as high as 60 ℃. At such high temperatures, coupled with sulfuric acid absorption, corrosion, bacteria are killed and eliminated. Practice has proved that sulfuric acid off rickettsia eliminate angular leaf spot effect than other pharmaceutical seed dressing, boring, soaking more reliable and reliable Very popular group
