摘　　要：通过对不同播种时期(8月15日、8月30日、9月15日、9月30日、10月15日和10月30日)的光叶紫花苕种子生产进行了比较研究,结果表明:不同播期对生育期影响明显,播种越早的其生育期越长。随着播期推迟,其种子产量先增加后减少,在9月15日播种种子产量最高,达1 013.55 kg/hm2,10月30日播种种子产量最低,为292.2 kg/hm2。The seed production of Vicia Villosa Var.on different sowing date （8.15, 8.30, 9.15, 9.30, 10.15, 10.30） was studied in this paper. The results showed that the sowing date could significantly affect plant growth period. The earlier the plant sowed, the longer the plant growth period lasted. The seed yield was increased and then decreased with the delay of sowing date. The highest seed yield reached 1013.55kg/hm^2 was obtained with sowing on the September fifteenth; the lowest seed yield reached 292.2kg/hm^2 was obtained with sowing on the October thirtieth.
