Abstract
A field experiment was conducted to study the effects of different amounts of selenium fertilizer on alfalfa growth,quality and nutrients absorption.The results showed that appropriate application rates of selenium fertilizer could increase the alfalfa yield,plant height and leaf/steam ratio,and promote alfalfa growth.And 0.45 kg hm-2 of selenium was the most effective and suitable application rate.Applying selenium could increase the content of crude protein,crude fat and crude ash in alfalfa,and decrease the alfalfa crude fiber content,and 0.45 kg hm-2 of selenium was the most effective application rate,where the contents of crude protein,crude fat and crude ash in alfalfa were separately 16.28%,6.29% and 8.56%,while the content of crud fiber was 34.92%,decreasing by 3.50% compared to CK.Applying selenium could also increase N,P and K absorption amounts,and 0.45 kg hm-2 of selenium was the best.The content and absorption amount of selenium were increased with the increasing Se application rate.The correlation coefficients between applied selenium amount and alfalfa Se content and Se absorption amount were 0.977** and 0.988** to significant levels,respectively.
