稀土元素与生物活性菌肥对农作物的促生效果

Rare earth elements and biologically active fertilizer interaction promoting effect of several major crops

以开发稀土元素辅助的高效生物活性菌肥为目的,采用盆栽大豆、小麦、玉米、水稻为实验材料,分别用稀土元素协同活性菌肥溶液、稀土元素溶液、活性菌肥溶液和蒸馏水定期浇灌,测定植物幼苗相关生长指标.结果显示,稀土元素及活性菌肥溶液对供试作物均有一定促生效果,但稀土元素协同活性菌肥溶液的促生效果更优越.稀土元素协同活性菌肥的使用有更高的潜在肥力.

In order to assist the development of efficient bio-active rare earth element fertilizer with potted soybean,wheat,maize,rice as experimental material,and with the rare earth element synergistic activity fertilizer solution,a solution of rare earth elements,active-fertilizer solution and distilled water regularly watered respectively,the relevant plant seedling growth indexes are determined.The results show：rare earth elements and active-fertilizer solution on the test crop have certain growth-promoting effect,but synergistic activity of rare earth elements fertilizer promoting effect is superior solution.The use of rare earth elements synergistic activity fertilizer possesses a higher potential fertility.
