摘要: 1953年作者曾对华北地区小麦春冻的情况作了分析和研究,1954年5月下旬曾去张北调查了苜蓿的冻害,1955年2月下旬及1955年12月至1956年1月又考察了华南热带的霜冻。本文拟就调查所得和见闻所及,对地形与霜冻的关系,略加阐述。

Abstract: The author has in the past four years been afforded opportunities to inves-tigate the problem of frost damage, such as the frost bite of wheat in North China, of forage plants in the Changpei Area, and of tropical plants in South China. In the course of these ins=estigations the author has keonly felt the close relationship between topography and frost damage. If favourable topography is chosen for plants, the frost damage rrLay be avoided or lessened to some extent. In this paper, the author based on leis past investigations makes a com-prehensive report particularly on mutters concerning topography in holes that it map be helpful to agriculture in taking precautions against frost damage.
