【摘要】 牧草植物量的形成受许多因素的影响,其中以降水和温度最为显著。在高寒地区,牧草植物量受气温影响最大;而在干旱地区,降水的作用最为突出,气温则次要。除此之外,它还受土壤、放牧强度、刈割、施肥、焚烧等的影响。就这些因素作一简要的介绍,为今后有关植物量的研究提供了一个比较系统的认识和依据,对指导牧草生产具有重要的意义。更多还原

【Abstract】 The formation of forage phytomass is affected by many factors, in these factors, precipitation and temperature are the most important. In the alpine areas, temperature is the key factor. However, in the drought areas, precipitation is the key issue. Besides, soil, grazing intensity, cutting, fertilizer application and fire are main factors as well. The paper revieaed the effect of these factors in order to provide the more systemic understand and foundation for future work.更多还原
