为了寻找与红花绿肥、红萍配套的二季晚稻肥源,几年来我们在湖北水生生物研究所的指导下,进行了固氮兰藻在水稻、棉花上的应用试验,获得初步结果。1974年,我们用固氮兰藻作二季晚稻秧田底肥获得较好结果。1975年起把兰藻应用到二季晚稻大田。方法是:二晚插秧后,田里保持1—1.5寸深的水层,趁晴天每亩施过砱酸钙或钙镁磷肥和草木灰各10—15斤。每亩用鲜藻80—100斤或磨碎的干藻粉4—5斤,充分捏碎,加上适易清水拌匀,用小桶分厢均匀泼入田里。待兰藻长满田后,让水自然落干,结合中耕压藻肥田。
In order to find the red rice with green manure, Hong Ping late autumn fertilizer, in the past few years, we under the guidance of the Hubei Institute of Hydrobiology, nitrogen and nitrogen-fixing plants in rice, cotton on the application of the test to obtain preliminary results. In 1974, we use Nitraria albina as late season rice seedling base fertilizer to obtain better results. Lan Lan was applied to the late-season rice fields in 1975. Method is: two nights after transplanting, the field to maintain 1-1.5 inches deep water layer, taking advantage of sunny days per acre applied calcium gallic acid or calcium magnesium phosphate and ash 10-15 pounds. 80-100 kg per mu with fresh algae or ground dried algae powder 4-5 pounds, fully crushed, together with easy to mix water, sprinkle evenly into the field with a bucket of sub-compartments. After the blue algae to be covered with fields, let the water fall naturally, combined with cultivating algae fertilizer field.
