下面介绍防治作物病害的土方法:高锰酸钾防治黄瓜,西瓜枯萎病,水稻的胡麻叶斑病等。在西瓜播种、幼期至伸蔓期,用高锰酸钾(俗名叫做“灰锰氧”)500～800倍液灌根,可将发病率控制在0.5%以下,效果很显著;在黄瓜幼苗期,用高锰酸钾800～1000倍液灌淋根部(每株用量为100毫升),每7～10天灌淋一次,连灌淋3次,不仅可以防治枯萎病等,还可促进黄瓜的生长发育,多结瓜。当水稻生长后期,发生胡麻叶斑病时,用高锰酸钾800～1000溶液喷布叶片,既能防治病,又能促进水稻的生长发育,对缺钾的田,作用尤为显
The following describes the prevention and treatment of crop disease soil method: potassium permanganate cucumber prevention and control, watermelon Fusarium wilt, rice flax leaf spot and so on. In the watermelon sowing, young to extending vine period, with potassium permanganate (commonly known as “gray manganese oxygen”) 500 to 800 times of irrigation, the incidence can be controlled at 0.5% or less, the effect is significant; cucumber seedlings Period, with potassium permanganate 800 ~ 1000 times the liquid irrigation roots (each amount of 100 ml), every 7 to 10 days irrigation once, and irrigation 3 times, not only to prevent blight, but also to promote cucumber The growth and development, more knot melon. When flax leaf spot occurs in the later stage of rice growth, spraying the leaves with 800-1000 potassium permanganate can not only prevent disease but also promote the growth and development of rice.
