通过对血橙、温州蜜柑的调查和统计分析,探明了柑桔冠径、千周、叶面积系数和末级梢数对幼树早期产量有极显著影响,其中冠径、干周是早期丰产稳产的重要树体结构基础。树冠投影面积和复盖率与群体产量的关系较密切,二者共同对产量作用的决定程度最大,又互为制约和消长。为早果丰产栽培提供了依据。 Through the investigation and statistical analysis of blood orange and mandarin orange, it was proved that the crown diameter, the thousandth week, the leaf area coefficient and the number of the final grade had a very significant effect on the early yield of young saplings. The crown diameter and dry week were the early Essential tree structure for high and stable yield. The crown area and coverage ratio are closely related to the population yield. The two determine the extent of the effect of yield on the whole, but also restrict and reduce each other. Provided the basis for early fruit yield cultivation.
