| 摘 要： | 在香梨果实生长发育期,通过定期测定果实横、纵径,对香梨果实生长发育规律及其与气象因子的关系进行了初步探索。结果表明,香梨果实横、纵径均呈持续增长趋势,横、纵径每10 d增长量呈现出2个相互重叠的增长高峰。通过灰色关联度分析法得出,60 cm地温是影响香梨果实膨大的主导气象因素。利用逐步回归分析法,建立了香梨果实日增长量与气象因子的回归模型,通过检验,模型效果较好,可为果园科学管理提供理论参考。

| Abstract: | Through measuring the longitudinal and transverse diameters of Korla pear fruit in the growth and development period, the relationship between growth dynamics rhythm of Korla pear fruit and meteorological factors was analyzed. The results showed that the longitudinal and transverse diameters of pear fruit had a sustained growth trend, and their growth amount of every l0 days had two overlapping peaks. Grey relational analysis showed that the average 60 cm ground temperature was the dominant meteorological factors affecting the enlargement of pear fruit. A regression model between daily pear fruit growth and meteorological factors was developed using stepwise regression analysis to provide theoretical reference for the scientific management of orchards. |
