3 稻米品质与环境因素的相关、通径和回归分析表9是早籼和晚稻两组资料合并后的米质指数与灌浆成熟期的气象要素之间的相关系数表。从表9看出,气温三指标(平均气温、最高气温、最低气温)之间呈高度正相关;气温与平均相对湿度之间呈极显著负相关;平均相对湿度与最小相对湿度之间呈中度正相
Correlation, Path and Regression Analysis of Rice Quality and Environmental Factors Table 9 is a table of the correlation coefficient between the combined rice quality index and the meteorological factors of grain filling and maturity. It can be seen from Table 9 that there is a highly positive correlation between the three indicators of air temperature (average temperature, maximum air temperature and minimum air temperature); there is a significant negative correlation between air temperature and average relative humidity; between average relative humidity and minimum relative humidity Degree is positive
