黄土丘陵区枣树形态指标与产量的相关性研究

Correlation Studies Of Jujube Yield To Its Morphological Growth Indices

本文对山西省主栽枣树品种木冬及优良推广品种石楼大枣的形态指标与产量相关性进行分析研究,结果表明:不同品种主要形态指标与产量相关程度不同:同一品种枣树以干周,冠径,果重和吊果率与产量关系最为密切,枣树形态指标在一定程度上能直接反映该树体的合理负载量。

The correlation of jujube yield to the morphological growth indices of two popular jujube cultivars named Muzao and Shilou Big Fruit in the loessal hillsides was studied. Analysis shows thatthe level of correlation differs with each cultivar. Among the same cultivar the yield is largely dependent on the stem circumference, crown diameter, fruit weight, and spur-fruit ratio. Such morphological indices of the jujube tree can, to a certain extent, directly reflect its rational loading capacity.
