Abstract
In order to explore the relationship between application of nitrogen fertilizer and seed yield of Leymus chinensis,the effect of applying nitrogen at different rate in different growth stages on seed yield and its component of Leymus chinensis were studied with split-block experimental design.The results showed that nitrogen had no significant effect on heading percentage or heading number,but significantly increased the seed-setting rate,seed number and 1000-seed weight.Applying nitrogen in last summer and fall had no significant effect on seed setting rate and seed number,but increased the reproductive shoots per square meter.Applying nitrogen 26.08g/m2 in April had significant effect on seed setting rate,1000-seed weight and seed yield,applying nitrogen 26.08g/m2 in July had significant effect on heading number per square meter and seed yield of Leymus chinensis in next year.
