“7841”,化学名为3—(2—吡啶基)丙醇,由南开大学元素所于1978年合成,又名“PGR—1”,是一种新型高效的植物生长调节剂,经七个省、市的有关单位四年来的药效试验表明,“7841对大豆、花生等作物增产效果显著。据统计,以每亩用1克“7841”调节剂的稀释药液浸种1.5—2小时,大豆可增产22％,花生可增产16—26％。如天津市蓟县,在2,000亩花生田作示范试验,平均每亩增产15.9％,共增加收入36,000元,药剂费只化了80元。再如黑龙江省牲丹江地区,在110亩大豆田上作试验,经喷洒药剂的办法处理后,增产大豆5,000余斤,扣除药费,净增加收入1,500元左右。“7841”对人畜
“7841”, the chemical name is 3- (2-pyridyl) propanol, was synthesized by Nankai University in 1978, also known as “PGR-1”, is a new and efficient plant growth regulator, Provincial and municipal authorities over the past four years, the efficacy test showed that “7841 on soybean, peanut and other crops yield significant effect.According to statistics, with 1 gram per acre” 7841 “conditioner diluted liquid soaking 1.5-2 hours, Soybean yield increase of 22%, peanut yield increase of 16-26% .As in Tianjin Jixian, 2,000 acres of peanut field demonstration test, an average yield of 15.9% per mu, a total increase of 36,000 yuan income, drug costs only 80 yuan. For example, in the Danjiangjiang area of Heilongjiang Province, testing was conducted on 110 mu of soya bean fields and after spraying, the yield of more than 5,000 jin of soybeans was deducted and the net increase of income was about 1,500 yuan. ”7841"
