蔓枯病是黄瓜种植时候的常见病之一了。蔓枯病一般都是因为土壤种的病菌没有进行消毒，使得细菌从虫子啃食的伤口处进行的感染。这种病害是具有感染性的。在初期的时候叶子感染藤蔓使得藤蔓上面出现一些黄色的斑点。在后来黄色的斑点就会变成黑的的斑点了。如果不管它的话斑点就会扩大渐渐的会使整株藤蔓出现枯萎死亡的情况。
蔓枯病在连绵的雨后最容易发病。在发病的初期可以使用浓度为百分之30的甲霜恶霉灵进行稀释之后喷洒到叶片上这样就可以很好的治疗蔓枯病了。在喷洒的时候并不是喷洒一次就完事了。在用药剂喷打过后的5到6天之后好药再进行喷打一次这样可以避免病害的再次出现。在你种植黄瓜之前先将土地进行杀毒也是一个很好的预防方法。
茎腐病可以说是黄瓜出现减产的祸首之一。它不仅发病快，感染力也是都十分强的。这种病一般都是由根系出现腐烂而引发的。在开始的时候黄瓜的藤蔓就像是缺水一样发黄。渐渐的根系就会出现白色的霉点。最后就会使得整个根系全部坏死使得藤蔓出现死亡。所以大家在种植的时候发现黄瓜叶片发黄的时候千万不要急着浇水。这样反而会使得病害加重。在叶片发黄的时候先将土壤挖开一点看土壤是否干燥。如果土壤还是潮湿的话，就说明并不是缺水而是病害了。在这时候就要停止浇水用恶霜嘧铜菌酯进行喷洒防治了。在喷洒的时候看一下发病藤蔓的根部，如果出现白色的霉点的话就要将它拔出来进行销毁。
茎腐病大多是土壤里面的病菌没进行杀毒，加上现在浇水或者下雨的时候有积水没有排出去。黄瓜的根系被积水侵蚀腐烂之后被病菌感染造成的。所以在种植的时候一定要先给土壤杀毒。在进行浇水的时候要做到急灌急排。不要让积水留在田地里了。这样就可以防止因为水分的原因使得根系出现腐烂。在种植的时候加强黄瓜的通风也是减少黄瓜受到病害侵袭的方法之一。
黄瓜种治病并没有这方面的科学报道。请你不要太相信有些人的说法。
这是什么偏方吧，感觉不可信。还是采用科学的方式治病比较靠谱
不对黄瓜种植并怎么使用黄瓜种植病啊使用是用科学方法
