摘要
1999年在内蒙古锡盟东乌珠穆沁旗的草甸草原上 ,研究了贝加尔针茅等 12种植物的生长发育规律及草群地上生物量变化动态 .研究结果表明 ,多数植物在春季返青时生长速度较快 ,抽穗 (孕蕾 )期生长速度达最大值 ,随后牧草的生长速度减慢 ,9月初生长停止 .草群地上生物量随牧草生长而增加 ,9月初生物量达最高值 ,随后又开始下降 .牧草的生长规律除决定牧草本身的生物学特性外 ,还受水热条件的制约。
The experiment was carried out to study the dynamics of growth and aboveground biomass of 12 species herbage in Hesigewula Ranch,Dongwu Banner,Xilinguole league,Inner Mongolia from May to September 1999.The results showed that (1)most plant`s growing velocity were faster at the beginning of the growing season,the maximum peak of growing velocity was earing period,then decreased,herbage growth stopped in September,(2)biomass dynamics of plant community was the same as plant growth,the peak of biomass appeared in beginning of September,then decreased.(3)Plant growth are decided by biological characteristics of plants,but closely correlated to environment conditions.
