不同整形方式对朋娜、纽荷尔脐橙生长及品质的影响

Effect of different training on growth and quality in Pengna and Niuheer navel orange

为了探明不同整形方式在脐橙上的应用效果 ,于 1999～ 2 0 0 0年对脐橙品种进行了不同整形修剪处理。结果表明 ,朋娜脐橙或纽荷尔脐橙以自然开心形的整形修剪方式较好 ,其次是自然圆头形和变则主干形。自然开心形能明显增强春、秋梢生长量 ,提高座果率 ,增加单位面积产量 ,改善果实品质 ,与不进行整形修剪的对照相比 ,朋娜脐橙座果率提高 6.4 4 % ,产量增产 80 % ;纽荷尔脐橙座果率提高 6.99% ,产量增产 83 1%。固形物、全糖、Vc等含量两品种都比对照高。在生产上建议推广自然开心形的整形方式。
