牧草从返青、抽穗、成熟到枯黄整个生育期主要受温度和水分条件的影响。牧草产量和品质的季节性变化与温度和降水的关系也十分密切。气候条件是决定牧草种类结构、形态特征和经济性状的重要因素。根据气候条件对牧草生长发育的影响,能更有效地改良和合理利用牧草资源,为进一步发展畜牧生产提供科学依据。 Forage from the green, heading, ripening to yellow throughout the growth period is mainly affected by temperature and moisture conditions. Seasonal changes in pasture production and quality are also closely related to temperature and precipitation. Climatic conditions are important factors that determine the structure, morphological characteristics and economic traits of forage species. According to the influence of climatic conditions on the growth and development of forage, the forage resources can be more effectively improved and rationally utilized, providing a scientific basis for the further development of livestock production.
