气候因子中,温度(热量)与牧草生长发育有密切关系,它与降水、湿度构成的地域水热条件是决定栽培草种分布的重要生态因素。在我国疆土辽阔,地域冷热悬殊,栽培牧草种类繁多的情况下,按栽培牧草生长发育对温度的要求和反应划分成相应的类型(称之为“需温类型” Climatic factors, the temperature (heat) is closely related with the growth and development of forage grass, and precipitation and humidity constitute the regional hydrothermal conditions is to determine the distribution of cultivated grass species is an important ecological factor. In our country’s vast territory, disparities in geography and heat, a wide range of cultivated pasture, according to the growth and development of forage grass growth temperature requirements and responses are divided into the corresponding type (called “temperature type”
