1985～1989年,从黑龙江省栽培大豆根瘤中分离出的27—50(快生型大豆根瘤菌)和22—10(慢生型大豆根瘤菌),经水培、砂培、盆栽和全省小区中试和大面积应用证明:27—50比美国菌种61A76多增产5.7％,亩多增收大豆7.8公斤,比不接种增产13.5％,亩增收大豆18.4公斤;22—10比61A76多增产3.7％,亩多增收大豆5.2公斤,比不接种增产11.2％,增收大豆15.9公斤。两个菌种应用面积已达103.2万亩。
From 1985 to 1989, 27-50 (fast-growing soybean rhizobia) and 22-10 (slow-growing soybean rhizobium) isolated from the cultivated soybean nodules in Heilongjiang Province were cultured in hydroponics, sand culture, pot and the whole province Community pilot and large-scale application of proof: 27-50 than the United States strain 61A76 more than 5.7% increase in yield, more than 7.8 acres of soybean yield increase, 13.5% more than non-vaccination, soybean yield increased 18.4 kg; 22-10 more than 61A76 yield 3.7 %, More than 5.2 acres of acres of soybean income, 11.2% more than non-vaccination, soybean income 15.9 kilograms. Two strains of application area has reached 103.2 million mu.
