蒙农红豆草不同成熟期种子的产量与品质分析

Seed Yield and Quality Analysis of Onobrychis viciifolia scop.cv. Mengnong in Different Harvest Periods

对不同生长年限及生长第 4年早熟、常熟、晚熟、刈割后二茬收种的蒙农红豆草种子进行产量构成因子、种子产量及品质测定分析。结果表明:在呼和浩特市地区 6月 30日前成熟(早熟)的蒙农红豆草种子产量与品质最佳;在花蕾期刈割收草,二茬收种也是一种较好的利用方式,虽然种子产量稍低,但种子品质与早熟种子相当。

The factors related to yield, seed yield and quality of early mature ,normal mature ,late mature,and the second harvest seed after first cutting were analysed. The results showed that the seed yield and quality of Onobrychis viciifolia scop.cv.Mengnong (early mature variety) before June 30 th harvesting were the best,It was a good way to harvest seed after first cutting in forage flowering stage ,but the seed yield was lower and the seed quality was the same as that of seed of early mature of no cutting .
