| 摘 要： | 采用硝酸稀土浸种的方法对6种优良牧草及饲料作物进行了应用性研究。研究表明:稀土的最佳利用范围为350×10-6～650×10-6,它对植物的生长促进作用主要体现在营养生长阶段,和对照组相比,稀土可极显著地提高6种牧草的生物学产量,同时对5种禾本科牧草的经济产量也有明显的增产效果,但对紫花苜蓿的经济产量没有显著作用。

| Abstract: | This paper studied the application of rare earth to six species of forage under 9 different water concentrations used for seed soaking. The results showed that the optimum range of rare earth solutions should be controled 350 X 10-6 - 650X 10-6,and rare earth promotes the growth of forage mainly in the vegetative stage, which has significant effects on biological yields for all forages and certain effect on economic yields for five species of grasses, but no influence on economic yield of alfalfa. |
