以6年生“西林3号”核桃为材料,通过果实生长动态测定,分析了“西林3号”核桃果实三径(纵径、横径及线径)生长规律及不同时期果实三径增长量与主要气象因子的相关性。结果表明:“西林3号”核桃果实生长过程可分为果实膨大期和果实成熟期2个阶段。在果实膨大期,气温和土壤温度与果实三径增长量之间呈正相关关系,而降水量、土壤湿度及空气相对湿度与果实三径均呈负相关关系。在果实成熟期,5个气象因子与果实三径增长量之间均呈负相关关系。
The 6-year-old “Xilin 3” walnut was used to study the growth of three diameter (vertical diameter, horizontal diameter and diameter) of “Xilin 3” and the fruit three Correlation between diameter increase and main meteorological factors. The results showed that the growth process of walnut fruits in “Xilin No.3” could be divided into two stages: fruit enlargement and fruit ripening. During the period of fruit enlargement, there was a positive correlation between air temperature and soil temperature and fruit three-diameter increment, while precipitation, soil moisture and air relative humidity were negatively correlated with fruit diameter. At maturity stage, there was a negative correlation between the five meteorological factors and the three-growth of fruit.
