摘要
为研究温州蜜柑果实膨大与水环境的关系,通过对2007-2012年柑橘果实膨大资料与水分资料研究。结果表明：柑橘果实膨大具有抛物线特征,在桂北地区6月中上旬至9月中旬果实生长迅速,其余时段果实生长缓慢,符合作物果实生长曲线规律;膨大速度与降水量、土壤重量含水率呈显著正相关;土壤相对湿度大于80%时与果实体积增量呈负相关;与湿润指数呈线性回归关系,果实膨大速度随着湿润指数的增大而加快。
Based on the study of citrus fruit enlarging and moisture data from 2007 to 2012, the results showed that the citrus fruit enlarging rate with parabolic characteristics, which has the rapid growth from the first and middle ten days of June early to middle ten days of September in north area of Guangxi while which has the slow growth during the rest of the time. This fits the law of fruit growth curve; there is a significantly positive relationship between enlarging rate and precipitation, moisture content to soil weight, until the soil relative humidity more than 80% there is a negative correlation with fruit volume increment; wetness index and fruit enlarging rate have a linear regression relationship, which one index accelerate with the increase of another.
