国光为晚熟耐藏的优良品种之一。在正常情况下,一般需要4—6年开始结果,8—10年后进入初果期。由于开始结果期较晚,早期产量低,因此严重影响了生产上的早期收益和本品种的迅速发展。多年来,为了探讨国光幼旺树提早结果和早期丰产的技术,国内外进行了大量的研 Guoguang late-resistant varieties with good resistance. Under normal circumstances, it usually takes 4 - 6 years to start the results, 8 - 10 years into the initial fruit period. Due to the late start of the production and the low production in the early stage, the early returns to production and the rapid development of this variety have been severely affected. Over the years, in order to explore the early results Guoguang Wang tree and early harvest technology, a large number of research at home and abroad
