高锰酸钾又叫灰锰氧、P.P粉,呈紫黑色结晶,有金属光泽,可溶于水,是一种强氧化剂,因能放出新生态氧而具有杀菌作用;高锰酸钾还同时含有钾和锰这两种植物生长发育所必需的营养元素,因而又是一种很好的化学肥料。它在农业上的应用主要有: 防治西瓜枯萎病西瓜枯萎病是一种毁灭性的土传真菌病害。据试验,在有枯萎病发生的地块,分别于西瓜播种、幼苗和伸蔓三个时期,用500～800倍的高锰酸钾溶液作垄面喷施和灌根,一般可将西瓜枯萎病发病率控制在0.5%以下;生长期植物初见萎蔫时,用500倍液灌根,治愈
Potassium permanganate, also known as gray manganese oxygen, PP powder, was purple black crystal, metallic luster, soluble in water, is a strong oxidant, because of the release of new eco-oxygen and has a bactericidal effect; potassium permanganate also Contains potassium and manganese, the growth and development of the two plant nutrients, which is also a good chemical fertilizer. Its application in agriculture are: prevention and control of watermelon fusarium wilt Fusarium wilt is a devastating earthworm disease. According to the test, in the plots where blight occurs, watermelon blight disease is generally sprayed and drenched with 500-800 times of potassium permanganate solution for watermelon planting, The incidence rate is controlled below 0.5%. When plants in growing season witness wilting, they are irrigated by 500 times and cured
