摘要
为了综合评价黄连木单株产量的影响因素,以太行山区的40株表型优良的黄连木优树为试材,就其13个相关因子对其单株产量的影响情况进行了调查与分析。结果表明:土壤肥力、虫果率、海拔、冠幅、果穗粒数、结果枝率、百果质量这7个因子都与其单株产量显著相关,其中虫果率、土壤肥力、果穗粒数是单株产量的主导影响因子,而树高、胸径、海拔、冠幅等因子对黄连木产量也有较为明显的影响。这一研究结果说明了黄连木果实产量是一个综合数量性状,只有各个影响因子协调作用,才能达到高产的目的。
In order to comprehensively evaluate influence factor of yield in Pistacia chinensis, taking 40 superior trees with excellent phenotypes as materials, the main factors affecting individual yield were investigated and analyzed. The results showed that soil fertility, insect-fruit rate, altitude, crown area, fruit quantity, proportion of fertile branches and hundred fruit mass had significant correlations with individual yield. Among these characters, insert-fruit rate, soil fertility, fruit quantity were leading factors contributing to individual yield, and tree height, DBH, altitude, crown area also had some influence on individual yield. So individual yield in P. chinensis was a comprehensive quantity character, and every factors coordination ftmction could help to realize high yield.
