解放以来,随着农业生产发展的需要,浙江省施用矿貭磷肥的数量,逐年增多;特別是近两年来,在各級領导亲自参加試驗的推动下,施用数量墳加的更快。1963年全省共銷矿貭磷肥9万多吨,此1962年增加44％,此1953年增加50多倍,其中約有20％是直接施用在水稻上的。浙江省1962—1963年冬作施用矿貭磷肥的效果已进行了初步总結。1963年各地所进行的水稻施用矿貭磷肥科学試驗,由于布点工作 Since liberation, with the development of agricultural production, the amount of phosphate fertilizer applied in Zhejiang Province has been increasing year by year. Especially in the past two years, with the promotion of pilot participation by leaders at all levels, the quantity of phosphate fertilizer applied is even faster. In 1963, more than 90,000 tons of phosphate fertilizer were sold in the province, an increase of 44% in 1962 and an increase of 50 times in 1953, of which about 20% were directly applied to rice.
