麻雀啄食秧田稻谷所造成的损失是很严重的。为了防止雀害,要有专人整天驱赶,花费劳力。我们采用呋喃丹农药浸种,毒杀麻雀的效果很好,1只麻雀取食4—6粒毒谷,即可中毒死亡。呋喃丹农药浸种的具体方法是:在100斤清水中,加入3％呋喃丹颗粒剂3—5斤,可浸100斤左右的稻谷。因呋喃丹颗粒剂难溶于水,因此,应在浸种前1—2天,先用少量水浸农药,经常搅拌,过几小时将药水倒出,再加入清水,不断搅拌,过数小时再将药水倒出,如此重复数次,使药剂尽量溶解,将各次倒出的药液混合,达到原定要求的浓度。残留的颗粒剂药渣,也要混入稻谷里,一同浸种。先将稻谷浸于清水中,捞出浮谷,沥水后,浸入上述药液中。在浸种期间,搅拌几次,使药渣和稻谷混和。浸种2昼夜后,捞出稻谷,沥干药水,就可按当地习惯催芽播种。稻
Sparrows pecking rice fields caused by the loss is very serious. In order to prevent the calamity, have someone to drive all-day, labor-intensive. We use carbofuran pesticide soaking, killing sparrows very good effect, a sparrow feeding 4-6 tablets poison valley, you can poisoning death. Carbofuran pesticide soaking the specific method is: 100 pounds of water, add 3% carbofuran granules 3-5 pounds, 100 pounds can be soaked paddy. Because of brittle carbofuran granules insoluble in water, therefore, should be 1-2 days before soaking, first with a small amount of water immersed pesticides, often stirring, pour the syrup over a few hours, then add water, stirring constantly, after a few hours and then The medicine poured out, so repeated several times, so that agents dissolve as much as possible, will be poured out of the liquid mixture, to meet the original requirements of the concentration. Residue granules dregs, but also mixed into the rice, soaking. First soak rice in water, remove the floating valleys, drained, immersed in the liquid medicine. During soaking, mix several times to mix dregs with rice. Soaking 2 days and nights, remove the rice, drain syrup, you can germinate according to local customs seeding. rice
