新疆栽培的苜蓿主要是紫花苜蓿,它根系庞大,茎叶繁茂,富含蛋白质和维生素,不仅是良好的饲料,而且能培肥土壤,不论高温还是高寒地区均能种植。1980—1985年,我们与北京农业大学生物学院协作,对新疆不同生态条件下的豆科植物根瘤菌资源进行了调查,共采集分离到苜蓿根瘤菌20株,经生理生化测定、回接、盆栽试验和小区试验筛选出了苜蓿根瘤菌优良菌株,并生产了根瘤菌制剂,应用于生产,取得了良好效果。现将试验结果简介如下。 供试菌株为筛选出的030、15紫花苜蓿、 Xinjiang is mainly cultivated alfalfa alfalfa, which has a large root, lush stems and leaves, rich in protein and vitamins, not only is a good feed, but also to fertilize the soil, both high and low temperature areas can be planted. From 1980 to 1985, we collaborated with College of Biological Sciences, Beijing Agricultural University to investigate the rhizobium resources of leguminous plants under different ecological conditions in Xinjiang. Twenty strains of Rhizobium meliloti were collected and analyzed. After physiological and biochemical determination, Experiments and plots trials selected strains of Rhizobium meliloti, and produced rhizobia preparations, applied to the production, and achieved good results. The test results are summarized below. Test strains for the screening of 030,15 alfalfa,
