富镧稀土对甘蓝增产效应的研究

A Research of Effects of Rich Lanthanum Rare Earth on Increasing the Yield of Wild Cabbage

适宜浓度的稀土处理可促进甘蓝种子萌发，加快营养体生长，提高光合速率，增强抗逆性，使甘蓝增产。而且富镧稀土2号的处理效果优于硝酸稀土。

This paper studies the influence of rare earth treatment on the wild cabbage yield. It is found through this research that after seeds were dressed with rare earth of the certain concenterations, the germination of wild cabbage seeds was promoted, the rate of the growth of wild cabbage was speeded, the rate of photosynthesis was enhanced and the resistent adversity was improved. Therefore, the treatment with rare earth can raise wild cabbage yield. Furthermore, the treatment of rich lanthanum rare earth is superior to that of nitric acid rare earth.
