Abstract:
The ecoclimatic adaptability and favorable and unfavorable climatic conditions during growth season of main herbage cultivars in the delta of the Huanghe River were analysed, the climatic productivity and its potential increment were estimated, not only in the natural grassland but also in the cultivated grassland, and measures of grassland improvement were given. The results show that annual climatic potential productivity is 9210—11820kg/ha and annual climatic potential increasing productivity is 4500—10500kg/ha in the natural grassland, and in the grassland with cultivated alfalfa they are 23775—28080kg/ha and 6000—19500kg/ha respectively.
