摘　　要：本试验运用二因素二次饱和Ｄ—最优设计，研究了磷肥和行距及其组合对草坪草多年生黑麦草和高羊茅种子产量和品质的影响。试验结果表明：磷肥和行距及其组合不但可以提高草坪草种子产量，而且可以改善草坪草种子品质，提高种子的发芽率、生长势和活力指数。磷肥和行距及其处理还可提高草坪草的每穗籽粒数、结实率和千粒重。The effects of phosphate fertilizer,row spacing and their combination on the seed yield and qualities ofLolium perenne and Festuca arundinacea were studied by the method of two factor sturated D-the best design.The results showed that phosphate fertilizer,row spacing and their combination could not only increase seedyield of turfgrasses but also improve their seed qualities.The germination percentage, growing power andindex of vitality of seed were improved,and the kernel/spike,setting percentage and 1000-seed weight ofturfgrasses were also improved.
