为探讨生产上马铃薯退化的原因及其防止措施,河北省张家口地区农业科学研究所从1950年开始,进行了一系列试验调查。现根据积累资料分述如下。 退化原因 一 高温对马铃薯的影响 (一)结薯期温度与退化的关系 1.不同地理环境与退化的关系。一般海拔或纬度高的地方退化都较轻,1953—1955年张家口地区农科所与中国科学院微生物研究所合作的调种试验指出,马铃薯退化程度
To investigate the causes of potato degeneration in production and its prevention measures, Zhangjiakou Institute of Agricultural Sciences in Hebei Province started a series of pilot surveys since 1950. Now based on the accumulated data are as follows. Degeneration causes a high temperature on the potato (a) the temperature and degradation of tuber the relationship between the 1 different geographical environment and degradation. General degradation of altitude or latitude are light places, from 1953 to 1955 Zhangjiakou Regional Institute of Agriculture and Institute of Microbiology, the cooperation of the adjustment test that the degree of degradation of potatoes
