摘　　要：将豆禾混播放牧草地植物组分分成红白三叶、多年生黑麦草、鸭茅、单子叶杂草、双子叶杂草和死物质 6种进行季节动态研究 ,进而对该草地牧草季节供给质量进行评价 ,找出生产管理上的不足并加以改进。研究表明 ,该人工草地管理利用较合理 ,但仍有一些地方需进一步改善 :鸭茅占优势 ,但豆科牧草含量偏低 ,多年生黑麦草过早消亡 ;冬春季节死物质含量过高 ,夏秋季节利用强度不足。草地供给的牧草质量 10月份最高 ,播种牧草含量达 77.2 0 % ,4月份最差 ,为 17.4 3% ;而可利用牧草含量最高为 9月份 ,达 10 0 % ,12月最低 ,为 2 0 .0 6%。The seasonal dynamics of pasture composition for pastures containing red and white clovers, cocksfoot, perennial ryegrass and weeds (native grass and broadleaf) were studied. The study included an evaluation of pasture quality—this information were used to adjust and improve management. The system, Cocksfoot is the dominant species in the pasture, followed by clover with perennial ryegrass making up only a small part of the sward. Pasture quality is highest in October and lowest in April.
