铵水,是煤矿炼焦的一种副产物,能防治稻浮尘子、稻飞虱、螟虫、稻蝗、稻椿象等多种虫害,并且是一种好肥料。湖南邵东、涟源等县煤矿大量出产,群力煤矿每天大约有万多斤,无偿供应。 过去,大家都未注意运用铵水,煤矿也不好处理,流入小河毒死鱼虾。在大搞土农药治虫中,有的群众便用来杀虫。最近,邵东县土农药治虫试验工作组用来作防治稻浮尘子、稻飞虱的试验,有70—80％的效果,用50只稻椿象分别进行施药与不施药的对比试验,经24小时检查,打了铵水的100％死亡,未打铵水的仅自然死亡10％,火厂坪公社双泉生产队也用铵水在伏瓦冲一亩试验田中作了对比,结果2/3施了铵水的田,害虫全部杀死,禾苗生长良好,比未施铵水的禾
Ammonia water is a co-product of coal coking and can prevent many pests such as rice fly dust, planthoppers, stem borers, rice locusts and rice stump ashes, and is a good fertilizer. Hunan Shaodong, Lianyuan County coal mines produced in large quantities, group coal mines every day about ten thousand jin, free supply. In the past, we did not pay attention to the use of ammonium, coal is not good to deal with, into the creek poisoned fish and shrimp. In the big pest control pests, some people will be used to kill insects. Recently, Shaodong pesticide pest control test group used to control rice floating dust, planthopper test, with 70-80% of the effect, with 50 Toona sinensis respectively, respectively, with and without the application of pesticide comparative test by 24 hours inspection, hit 100% of the death of ammonium, ammonium did not hit the water only 10% of natural death, fire factory Ping Shuangquan double commune team also ammonium sulfate in the Fuwa Chong acre trial field made a comparison, the results of 2 / 3 applied ammonium water fields, all pests killed, seedlings grow well, than did not apply ammonium fertilizer Wo
