在缺乏相应根瘤菌的土壤中,对大豆接种根瘤菌剂,是有效的增产措施。贺兰山东麓新灌区近年大豆种植面积较大。我所1982年开始进行大豆接种根瘤菌肥效试验,1983年将试验扩大到地处贺兰山东麓的5个国营农场,共9个点次。现将试验结果报告如下。材料与方法大豆品种为铁丰18号。根瘤菌剂系辽宁省兽医生物药品厂生产,每克菌剂内含有活菌2亿以上。设小区试验和大田对比试验。小区试验设接种和未接种(对照)两个处理,顺序排列,重复4～6次,小区面积为
In rhizobium-deficient soils, inoculation of rhizobia into soybean was an effective stimulation. New irrigation area east of Helan Mountain soybean planting area in recent years larger. In 1982, we began to test soybean inoculation rhizobium fertilizer efficiency. In 1983, we expanded the trial to 5 state-owned farms located in the eastern foot of Helan Mountain, a total of 9 times. The test results are reported below. Materials and Methods The soybean variety was Tiefeng No.18. Rhizobium strains Liaoning Province Veterinary Biopharmaceutical Factory production, per gram of bacteria containing live bacteria more than 200 million. Set cell test and field contrast test. Community trial set inoculation and non-inoculation (control) the two treatments, arranged in order, repeated 4 to 6 times, the plot area
