本研究通过1965—1983年的含糖资料与气象资料的相关分析指出:1.含糖率和7—9月份的昼夜温差(D)及光照时数(S)呈正相关。其中,重要程度的顺序是:S_8>S_9>S_7,D_9>D_8>D_7。2.含糖率一般和生长中后期的降雨量呈负相关.不过,在甜菜种植老区,含糖率和6月份及9月份降雨量呈明显的负相关。3.含糖率,在湿润及灌溉地区和5月份平均气温呈正相关,除北部产区外,和6月份及7月份平均气温呈二次曲线相关。一般和8月份平均气温呈负相关;在北部产区和9月份平均气温呈正相关。4.含糖率与3月份和9月份降雨量的交互值,8月份降雨量和平均气温的交互值呈正相关,与8月份平均气温和光照,9月份昼夜温差和降雨量的交互值呈负相关.
The correlation between sugar content and meteorological data from 1965-1983 was analyzed in this study: 1. The sugar content was positively correlated with the temperature difference between day and night (D) and light hour (S) from July to September. Among them, the order of importance is: S_8> S_9> S_7, D_9> D_8> D_7.2. The sugar content is generally negatively correlated with the rainfall in the middle and late growth period. However, And the precipitation in September showed a significant negative correlation. 3. The sugar content was positively correlated with the average temperature in May in wet and irrigated areas except quadruple curve except the northern producing areas and the average temperature in June and July. Generally, the average temperature in August is negatively correlated with the average temperature in August. There is a positive correlation between the average temperature in September and the northern part. The interaction between the sugar content and rainfall in March and September was positively correlated with the interaction between rainfall and average temperature in August. The interaction between the average temperature and illumination in August and the temperature and precipitation in September and in September was negative Related.
