近几年,我省在农业上应用稀土得到广泛推广。1990年全省施用稀土面积达58.3万亩,经289个试验、示范点测产,粮油作物亩增产19.7—52.8公斤,水果平均亩增产150.8公斤,蔬菜平均亩增产545.1公斤,亩增收17.16—150.8元,投入产出比为1:10—20,受到农民的普遍欢迎。但是,由于少数农民对这项新技术还没有完全掌握,也出现一些增产效果不明显的现象。为 In recent years, our province in agricultural application of rare earth has been widely promoted. In 1990, 583,000 mu of rare earths were applied in the province. After 289 experiments, the production of demonstration sites was measured. The output of grain and oil crops increased 19.7-52.8 kilograms. The average yield of fruit increased 150.8 kilograms. The average yield of vegetables increased 545.1 kilograms. The mu increased by 17.16-150.8 Yuan, input-output ratio of 1: 10-20, by farmers generally welcomed. However, due to the fact that a few peasants are not yet fully aware of this new technology, there have been some obvious phenomena of not increasing yield effectively. for
