牧草和其它植物一样,其生长发育和产量的形成,同生境因子,尤其是气候因子的关系十分密切。为此,我们根据内蒙古镶黄旗气象局最近三年牧草观测资料,对天然草场上羊草生育期、生长高度和产草量与气象条件的关系进行了初步分析,获得了一些初步的预报指标,建立了产量预报方程,为进一步开展牧业气象服务提供了依据。 Herbage, like other plants, has very close relationship with its habitats, especially climatic factors, in its growth and yield. Therefore, based on the pasture observation data of Inner Mongolian Yellow Flag Weather Bureau, we conducted a preliminary analysis on the relationship between the growth period, the growth height, the grass yield and the weather conditions of the natural grassland, and obtained some preliminary forecast indicators. Established the yield forecasting equation, which provided the basis for further carrying on the livestock meteorological service.
