我国自1972年开始在农业上应用硝酸稀土,十多年来,通过北京、天津、南京、黑龙江、湖南、江西等省(市)几万次盆栽、小区和大田试验,结果表明,稀土对水稻、小麦、大豆、棉花、花生、白菜、西瓜、茶叶、烤烟、甘蔗及果树花卉均具有增产效果和改进品质的作用。并具有成本低(每亩仅2～3角钱),使用方便的好处。我们于1985年在红麻上进行试验研究,现将结果总结于后:
China has applied rare earth nitrate to agriculture since 1972, and has experimented with tens of thousands of pots, plots and fields in Beijing, Tianjin, Nanjing, Heilongjiang, Hunan and Jiangxi provinces for more than a decade. The results show that rare earth Wheat, soybean, cotton, peanut, cabbage, watermelon, tea, flue-cured tobacco, sugarcane and fruit trees all have the effect of increasing yield and improving quality. And with low cost (only 2 to 3 cents per acre), the benefits of easy to use. We conducted a pilot study on kenaf in 1985 and we now summarize the results:
