农用复合肥添加稀土对小麦幼苗生长发育影响的研究

为了研究复合肥添加稀土后对农作物生长发育的影响，以小麦作实验材料，在复合肥中添加不同剂量的稀土后作底肥，考察了小麦幼苗的生长发育情况，并分析了稀土和微量元素在小麦幼苗中的分布。实验结果表明：复合肥中一定剂量的稀土可以加快小麦幼苗的生长发育，同时能促进小麦幼苗对有益微量元素的吸收，减少稀土在小麦幼苗中的无益积累。预示农用复合肥恭加稀土在农业生产中有一定的推广价值。

Effect of rare earth added agricultural compound fertilizer on growth of seedling of wheat

To study how rare earth added agricultural compound fertilizer effect on the growth of crops, wheat used for experiment material, different amount rare earth have been put into agricultural compound fertilizer used them for fertilizer, the growth of seedling of wheat was investigated, the content of rare earth and trace element in seedling of wheat was determinated. The result showed a suitable proportion constitute about rare earth added agricultural compound fertilizer accelerated the growth of seedling of wheat, it increased the content of useful chemical element and reduced accumulation of rare earth in seedling of wheat. So, the popularization of agricultural compound fertilizer with rare earth will have a for-reaching meaning in agriculture.
