Abstract: The regulation of aboveground biomass, underground biomass and total biomass of perennial ryegrass/white clover mixed pasture were studied in this paper.The results showed that the growth model of the aboveground biomass was a double-peak curve,while the underground was a three-peak curve.The three peaks were in the last of May, August and November.A mounth ahead of peaks time of under-eground biomass were found than of peaks time of aboue-ground biomass.The mixed pasture biomass was affected by the seasonal changs of perennial ryegrass and white clover.

Key words: Perennial ryegrass, White clover, Artificial pasture, Biomass

摘要: 本文研究了多年生黑麦草和白三叶人工草地地上生物量、地下生物量以及全植层生物量的形成规律。结果表明,地上生物量的形成曲线为双峰型,而地下生物量的曲线为三峰型,且后者峰值的出现时间较前者早近-个月;地上部和地下部生物量受两种牧草生长节律的制约。
