摘要
用浓度为50和100ppm的硝酸稀土混拌于育苗土中进行纸筒培育甜菜(Bata VulgarisL.)苗,发苗快,苗壮,移栽后缓苗快生长旺,叶丛繁茂,为增产增糖奠定了基础。
The experiment showed that the sugerbeet seedlings nursed in pape-rpot with 50 or 100 ppm rare-earth elements grew vigorously before and after its transplantation.Thus a foundation for a good yield of sugar has been laid.
