引言我们和中国科学院植物生理研究所合作,在湖南农学院进行杜仲栽培生理研究,于1953年3月开始,已经两年。试验工作主要为种子发芽和育苗二项。此外并于1955年营造杜仲试验林约一千株,病害数种正进行分离和接种和科学院植物生理研究所对幼苗含胶量的初步分析,分析结果根为满意。故湖南杜仲分布集中湘西,土质与长沙不同,长沙为红土层,两年来在红土层上进行试验,杜仲幼苗生长良好,生理正常,现在已可初步确定,在广大红土地带推广杜
Introduction We cooperated with Institute of Plant Physiology, Chinese Academy of Sciences to conduct Eucommia cultivation physiology research in Hunan Agricultural College. It started two years in March 1953. Experimental work mainly for seed germination and nursery two. In addition, in 1955, about 1,000 plants of Eucommia ulmoides were established, and several kinds of diseases were undergoing isolation and inoculation and the preliminary analysis of the gel content of seedlings by the Institute of Plant Physiology, Academy of Sciences. The results were satisfactory. Therefore, the distribution of Hunan Eucommia concentrated in western Hunan, Changsha and the soil is different, Changsha is the red soil, two years in the red soil test, Eucommia seedlings grow well, physiologically normal, it can be initially identified in the vast red soil extension
