接种根瘤菌是提高蚕豆产量有效的措施。A-19菌株是1980年我们从本市射阳县长荡乡蚕豆亩产超600斤的高产田块中分离筛选而来的。经四年室内鉴定和田间试验以及大面积示范,A-19菌株增产效果稳定。 A-19的生理生化特性 A-19是从蚕豆高产田块根瘤中分离的一株豌豆族根瘤菌。不仅可以用于蚕豆接种,也可以用于苕子、大荚箭舌豌豆、箭舌豌豆
Rhizobium inoculation is an effective measure to increase the yield of broad bean. A-19 strain was isolated and screened from the high-yielding field of over 600 kg per mu yielding fescue in Changdang Township, Sheyang County in 1980. After four years of indoor appraisal and field trials as well as a large area demonstration, A-19 strain has a stable yield increase. Physiological and biochemical characteristics of A-19 A-19 is a pea-based rhizobium isolated from the nodules of high-yield broad bean field. Not only can be used for broad bean inoculation, can also be used for prickly heat, pod tongue tongue pea, arrow tongue pea
