1989年海拉尔农牧场管理局哈达图牧场推广小麦根际联合同氮菌拌种技术,试验结果表明,用固氮菌拌种增产显著,经济效益高、成本低、使用方便、无污染、无副作用,是小麦高产的又一新措施。第一联合家庭农场2500亩夏翻地,使用固氮菌拌种,小麦品种采用克丰五号,亩施二铵10公斤,单产达390公斤,千粒重47克,容重800多克,每亩增产33.3公斤,比对照增产14％。经调查,施用固氮菌后,植株深绿,根系发达,增加穗粒数2～4粒,千粒重增加2克左右,叶宽增加1～2厘米,每平方米有效穗数在600株左右。施用固氮菌,每亩地成本1.50元,亩增
1989 Hailar Farms Authority Hadatu pasture to promote the wheat rhizosphere together with nitrogen seed dressing technology, the test results show that the nitrogen-fixing bacteria seed yield increase significantly, high economic efficiency, low cost, easy to use, pollution-free, no side effects , Is another new measure of high yield of wheat. The first joint family farm 2500 acres of summer land, the use of Azotobacter seed dressing, wheat varieties Kefeng 5, Mushi Shi diammonium 10 kg, yield of 390 kg, 1000 grain weight 47 grams, weighing 800 grams, 33.8 acres per mu Kg, 14% more yield than the control. After investigation, after Azotobacter was applied, the plants were dark green with developed root system. The number of spikelets increased by 2 ~ 4, the grain weight increased by 2 grams, and the leaf width increased by 1 ~ 2 cm. The number of effective spikes per square meter was about 600. Nitrogen-fixing bacteria, the cost per acre 1.50 yuan, mu increase
