草地的牧草生产性能最好是长期稳定高产,但普遍认为牧草产量经过几年就会逐渐下降。要保持原来的牧草生产性能,就要尽量维持高产牧草的良好的牧草组成和基本满足这些牧草生长所必需的养料、水分,并且利用得当。因此,牧草的生产性能在很大程度上受牧草组成、施肥管理、土壤的理化性质及草地的利用方法 Pasture productivity on grasslands is best stable and high-yielding over the long term, but pasture production is generally expected to decline over the course of a few years. To maintain the original forage production performance, it is necessary to try to maintain a good pasture composition of high forage grass and nutrients that are basically necessary for the growth of these pastures, and to make proper use of water. Therefore, pasture productivity is largely influenced by forage composition, fertilization management, physico-chemical properties of the soil and grassland use
