摘要
据黑龙江省1990年7个中试点试验证明,小麦根际联合固氮菌田间接种效果在5.2—20.6％,平均为9.8％;每田可增产小麦19.1公斤。小麦根际联合固氮菌能促进小麦本长发育,在生育期间可使株高、鲜重增加,叶色变缘。秋收考种证明,对产量构成因子的平方米穗数、穗粒数和千粒重均有增加。
The experiment 'in Heilongjiang province for 7 trial locations in 1990 proved that the inoculated effect with Azospirillum brasilense increased yield by 286.5 kg/ha, and by 5.2-20.6 %, in average by9.8%, Azospirillum, brasilense can be promote plant growth development, plant height and plant fresg weight increased, also leaf colour turned into green. Analysis of the yield component factors showed that inoculation increased the number of spikes per square motre, the number of grains per spike and 1000-seed weight.
