摘要
研究了云南高降雨地区混播草地播种60 d后,不同放牧强度(0.5,1和1.5黄牛单位/公顷)对草地密度、盖度、高度、频度和生物量的影响。结果表明,放牧能明显抑制一年生禾本科杂草及播种多年生禾本科牧草的生长,但对白三叶和草地有害植物的生长都有促进作用。
The effect of different grazing intensity on the density, coverage, plant height, frequency and biomass of the pasture sowed after 60 days (0.5, 1, 1.5 Yellow cattle/hm^2) in more rainfall area in Yunnan province has been studied. The results showed that grazing restrained the growth of annual gramineae weeds and perennial gramineae grass, but accelerated the growth of white clover and noxious plants.
