解放前福建省化肥消费量甚少,亩均施用量不到1斤。解放后随着化工生产的发展,化肥销售量大幅度增长。如以1950年销售量为1.0,则1960年为15.9,1970年为72.5,1980年则为296.3。现亩均化肥总用量已超过180斤。从1970—1979年的近十年时间看,氮素占全部化肥中三要素总量的76.3%,这似乎太多,以致氮肥的增产值有降低的趋势。据大量的田间试验统计,我省一斤硫按六十年代初平均可换得4—5斤稻谷,而七十年代却只能换回2—2.5斤,甚至更低些。磷肥在五十年代的肥效不大,群众对其不甚了解,所以长期滞销,以后随着试验、示范、
Before liberation, there was very little fertilizer consumption in Fujian Province, and less than 1 kg of mu was applied. After the liberation with the development of chemical production, sales of fertilizers increased significantly. If the sales volume in 1950 was 1.0, then it was 15.9 in 1960, 72.5 in 1970 and 296.3 in 1980. The total amount of fertilizer per mu are now more than 180 pounds. From 1970 to 1979, nearly ten years of time, nitrogen accounted for 76.3% of the total three elements of all fertilizers, it seems too much, so that the yield of nitrogen fertilizer tends to decrease. According to a large number of field trial statistics, the province’s pound of sulfur can be exchanged for 4-5 kg of rice by the early 1960s, but in the 1970s it can only be exchanged for 2-2.5 kg or even lower. Phosphate fertilizer in the fifties little effect, the masses do not quite understand it, so long-term poor sales, with the test, demonstration,
