锦橙密植园的生物学指标和光照强度与产量的相关性研究

STUDIES ON THE CORRELATION OF FRUIT YIELD WITH THE BIOLOGICAL INDEXES OF THE TRRES AND LIGHT INTENSITY IN DENSELY PLANTED SWEET ORANGE ORCHARDS

柑桔栽植密度、树冠覆盖率、叶面积系数和光照强度与产量呈极显著相关。锦橙密植丰产园的合理叶果比值为40～60:1,树冠覆盖率为50～70％,叶面积系数在5左右,树冠叶幕层的相对光照强度应大于15％。

The fruit yield of sweet orange was found to be highly significantly correlated with planting density, canopy cover rate, leaf area index and light intensity in densely planted orchards. The desirable leaf/fruit ratio, canopy cover rate, LAT and relative light intensity were estimated to be 40～60:1, 50～70%, 5 and>15%, respectively.
