板栗生产由于良种嫁接和促成雌花技术的推广应用,产量逐年提高。但也因棚数过多,而空棚率高、单粒重降低的问题,从而影响产量的提高。造成这种情况的主要原因是授粉不良与棚数过多。为解决授粉树的选择与合理负载量问题,于1980年进行了栗树授粉组合与疏棚试验,现将试验结果整理 Chestnut production due to seed grafting and promotion of the application of female flowers technology, production increased year by year. However, the number of sheds is too large, and the shed height is high, the problem of single grain weight reduction, thus affecting the yield increase. The main reason for this is the poor pollination and the high number of sheds. In order to solve the problem of pollination tree selection and reasonable load, the chestnut tree pollination combination and the canopy experiment were conducted in 1980, and the test results are arranged
