稀土可以促进作物生根、发芽和促进植物对氮、磷、钾大量元素的吸收,提高光能利用率,提高作物产量与质量。为了研究稀土在甜菜上的施用技术和增产增糖效果,解决我县甜菜产量不高、含糖量低的问题。我们从1981年开始,连续进行了五年7点次的田间试验和三年26点次的示范试验,面积达15,240亩。通过试验示范,进一步明确了甜菜施用稀土的增产增糖效果和施用技术。因此1985年全县推广了此项新技术,推广面积2.5万亩,占播种面积的92％。
Rare earth can promote crop rooting, germination and plant nitrogen, phosphorus and potassium to promote the absorption of large elements, improve light utilization, improve crop yield and quality. In order to study the application technology of rare earth on sugar beet and the effect of increasing sugar production, it solved the problem of low yield and low sugar content of beet in our county. Since 1981, we have carried out seven field trials of five years in succession and demonstration experiments of 26 points in three years with an area of 15,240 mu. Through the demonstration, further clarified sugar beet application of rare earth yield increasing sugar effect and application techniques. Therefore, the county in 1985 to promote this new technology to promote an area of 25000 acres, accounting for 92% of sowing area.
