牧草和其它植物一样,其生长发育的产量形成,在相当程度上受气候条件制约和影响。例如,返青的迟早、产量的高低、质量的好坏,都直接和气象条件有关。所以,研究牧草生长发育和产量形成与各种农业气象条件的关系,对于合理地开发利用气候资源,科学地规划牧草生产具有十分重要的实际意义。 Herbage, like other plants, is responsible for the formation and development of its growth and development and is, to some extent, conditioned and influenced by climatic conditions. For example, the sooner or later return green, the level of output, quality is good or bad, are directly related to weather conditions. Therefore, to study the relationship between forage growth and yield formation and various agrometeorological conditions is of great practical significance for the rational exploitation and utilization of climate resources and the scientific planning of pasture production.
