摘要
利用河南县牧气观测资料 ,根据垂穗披碱草的生物学特性 ,探讨牧草的再生能力与积温、草原干湿指数、产草量的关系 ,可作为科学利用草场 ,合理轮牧的依据。
Based on the Meteorological data recorded in Henan county of Hungnan Prefecture the relationship between the climate conditions (accumulating temperature and moisture index on pasture) and re-growth ability of Elymus nutans (grass yield) was studied.The results could be used as a the ological base for rational usage and rotation of pasture.
