摘　　要：板栗树雄花序较多 ,大量消耗树体营养 ,是造成板栗减产的 1个因素 ,故应用不同浓度的板栗疏雄醇开展了疏除板栗雄花的试验。初步摸索出在板栗花期喷布 10 0 0～ 15 0 0倍的板栗疏雄醇稀释液 ,能有效地抑制板栗雄花序的生长 ,对板栗混合花序有疏雄保雌的功能 ,可提高座果率 5 9%～ 10 8% ,增加栗果单粒重 0 6～ 1 1g。Large amount of male flowers which consume nutrients of tree was an important reason for production reduce of Chinese chestnut. Experiments of thinning male flowers by using SXC of different concentrations were carried out. The results indicated that spraying SXC 1/1 000～1/1 500 at flower phase could effectively restrain the male flower growth of Chinese chestnut, moreover, the male flowers of mix inflorescence were thinned, and the female flowers were kept, the percentage of fertile fruit and single seed weight were increased by 5 9%～10 8% and 0 6～1 1g respectively.
