我县于1984年引进北京农业大学增产菌在西瓜生产上进行试验,取得明显效果。1987年秋播小麦时又在杨镇、张镇、南彩等五个乡万亩麦田进行示范,其结果用增产菌拌种的千粒重增加0.4克,亩增产10.5公斤;1988年5月4日和5月17日喷施1～2次增产菌(亩用30毫升)千粒重增加1.3～3.7克,亩增产12.8～20.6公斤;后又给南彩乡晚麦(1987年10月12日播)独杆栽培上(4月27日)喷施25毫升,平均每穗增加1.2粒,千粒重增加2.2克,亩增产36.7公斤。今年秋播小麦时,我们以发简报、利用科技赶集和县科技报大力宣传增产菌的增产效
County in 1984 to introduce Beijing Agricultural University increased production of watermelon in the trial, achieved significant results. In the autumn of wheat broadcast in 1987, Yang Zhen, Zhang Zhen and Nancai were also demonstrated in the wheat fields of five townships such as Yangcun, Zhangcun and Nancai. The results showed that the yield increased by 0.4g and the yield increased by 10.5kg. May 17 sprayed 1 or 2 times to increase bacteria (mu with 30 ml) 1000 grain weight increased 1.3 ~ 3.7 grams, mu yield 12.8 ~ 20.6 kg; later gave Nancai Township late wheat (October 12, 1987 broadcast) alone Sparrow cultivation (April 27) spraying 25 ml, the average increase of 1.2 grains per spike, 1000 grain weight increased 2.2 g, mu yield 36.7 kg. When we broadcast wheat in autumn this year, we made a briefing to make use of science and technology to speed up the increase of yield-producing bacteria
