A STUDY ON CLIMATIC ADAPTABILITY OF THE HIGH- QUALITY HERBAGE INTRODUCED IN SOUTH CHINA
华南引种优质牧草气候适应性的研究

The two-year periodic experiments of three kinds of tropical herbage and three kinds of temperate herbage with good prospects in South China are summarized in this article. The study indicates that there is close relation between the growth and output of the herbage and the meteorological conditions. Meanwhile, it also identifies the meteorological indexes for the tropical herbage to survive winter and for the temperate herbage to survive summer. The frost injury index and advection cold injury index of tropical herbage and the hot injury index of temperate herbage are found. In addition, the climatic adaptability of the introduced high-quality tropical herbage and temperate herbage in South China are appraised and the problem of rational layout is also explored. The view-point of the authors is that the artificial pasture in South China should belong mainly to the middle and small types and that agriculture, forestry, and animal husbandry should join together.
