一、我省化肥施用概况肥料是作物的粮食,是增产的物质基础。很低。建国初期的1952年,全省化肥用量为75吨,随着化学工业的发展,化肥年产量迅速增加,用于农业的化肥也在急剧上升,至1983年竟达100.4万吨,三十一年间增长一万三千多倍。随着化肥的普遍施用,土壤养分逐渐提高,从而给粮食生产带来新的飞跃。今以武威县为例:1967年前该县主要抓病虫防治和解放前我省农业单纯依靠农家肥料,作物产量
First, fertilizer application in our province Overview Fertilizer is the crop of grain, is the material basis for increasing production. Very low. In the early years of the founding of our nation, in 1952, the amount of chemical fertilizer in the province was 75 tons. With the development of the chemical industry, the annual output of chemical fertilizers has increased rapidly. The amount of fertilizers used for agriculture has also risen sharply to 1.04 million tons by 1983, An increase of more than 13,000 times. With the general application of fertilizers, soil nutrients gradually increased, thus bringing a new leap forward in food production. Take Wuwei County as an example: Before 1967, the county mainly focused on prevention and control of pests and diseases before the liberation of agriculture in our province, relying solely on farm manure, crop yield
