过去我国农业界流行着“重氮轻磷”的观念。六十年代中,我国在植物的营养平衡和施用配合肥料方面,开始有了新的突破。1961年朱如源等在河北省新城县,1963年刘光崧等在安徽省砀山县,以及同年,作者与陈文彤、杨云蒸在安徽省肥西县,先后独立地发现了氮磷配合的巨大增产效果,从而解开了某些化肥低效、无效之谜。 1963、1964两年在淮南丘陵地区取得的初步结果,曾于1965年作了初步报导。1965—1968年期间,进一步在安徽淮北平原的青黑土地区试验,以提高肥效。同时示范推广两千
In the past, the concept of “diazo phosphorous” prevailed in the agricultural sector in our country. In the 1960s, China started a new breakthrough in the balance of plant nutrition and the application of fertilizers. In 1961, Zhu Ruyuan and other county in Hebei Province, 1963 Liu Guangsong in Dangshan County, Anhui Province, and the same year, the author and Chen Wen-tung, Yang Yun steamed in Feixi County, Anhui Province, has independently found a huge increase of nitrogen and phosphorus with a yield effect, Thus solved some of the ineffective fertilizers, invalid riddles. Preliminary results of the 1963 and 1964 hilly areas in Huainan were first reported in 1965. During 1965-1968, further tests were carried out in the black and black soil area of Huaibei Plain in Anhui to improve fertilizer efficiency. At the same time demonstration and promotion of two thousand
