草地生产率除受制于生产者技术水平而经常变汜波动外,还受着地理位置,土壤类型,气候条件等多种因素的制约。例如、采取施肥、灌溉等管理措施即可大幅度提高草地生产率,但最重要的是取决于优良的牧草种子。种子,作为草地农业最基本的生产资 In addition to being subject to the technical level of producers, grassland productivity often fluctuates, but it is also constrained by a variety of factors such as geographical location, soil type and climatic conditions. For example, management practices such as fertilization and irrigation can significantly increase grass productivity, but most importantly, depend on good pasture seeds. Seeds, as the most basic production of grassland agriculture
