稀土具有生理活性,合理施用,可以提高作物产量和质量。采用300PPM稀土溶液浸种和根瘤菌接种的沙打旺效果最佳。盆栽试验植株高度、植株鲜重、干重比接种根瘤菌增加11.1％,11.9％,8.1％。比清水浸种增加50.0％,30.4％和27.3％。小区试验,植株高度、植株鲜重、干重均比接种根瘤菌增加5.00％。比清水浸种分别增加8.4％,25.4％,18.2％。沙打旺施用稀土不仅对其有促进作用,而且对沙打旺根瘤菌有刺激作用。发挥它们的协同作用,其增产比单一稀土浸种或根瘤菌接种效果更好。植株高度平均提高12.6％,鲜草产量平均增加10.2％,干草产量平均增加10.0％,均较对照和其它处理表现显著或极显著。
Rare earth has physiological activity, reasonable application, can improve crop yield and quality. Stimulation with 300PPM rare earth solution and rhizobia was the best. The potted plant height, plant fresh weight and dry weight were 11.1%, 11.9% and 8.1% higher than those of inoculated rhizobia. Soaked than clear water increased by 50.0%, 30.4% and 27.3%. Community trials, plant height, plant fresh weight, dry weight than inoculated Rhizobia increased 5.00%. Soaked seeds were increased by 8.4%, 25.4%, 18.2% respectively. Sputtering application of rare earth not only promote their role, but also to stimulate sand Rhizobium spp. To play their synergistic effect, the yield increase is better than single rare earth soaking or Rhizobium inoculation. Plant height increased by 12.6% on average, fresh grass production increased by 10.2% on average, hay production increased by 10.0% on average, compared with the control and other treatments were significant or very significant.
