A Study on the Relations of Meteorological Factors and production of Chinese Cabbage

本文通过对气象因子与大白菜生产的关系研究,认为我区从1985年到1988年大白菜欠收,甚至绝产的主要原因是:1、1985—1988年7—9月份的平均气温明显高于正常的年份0.7℃.2、1985年至1986年大白菜欠收的主要原因是由于7—9月份高温干旱引起病毒病和干烧心病的大发生所致.1987年至1988年大白菜欠收的主要原因是由于7—9月份高温多雨引起霜霉病和软腐病大发生所致,并且提出了我区生产大白菜的对策.

In this paper, study was made on the ralations of meteorological factors and production of Chinese Cabbage. It was considered that the less-yeild even no-yeild of Chinese Cabbage from 1985 to 1988 caused by the average temperature in July and September which was 0. 7 'C higher than those of the other years. Between 1985 and 1986, the less-yeild of Chinese Cabbage was mainly due to the ocur-rence of virus and dried leaf caused by high temperature and drought in July and September. From 1987 to 1988 maily due to the occurence of downy milden and soft rot caused by high temperature and rich rain in July and Sept. Therefore the counter plots on production of the Chinese cabbage in durre-gion were giren.
