摘　　要：为了促进板栗雌花芽分化 ,提高板栗产量 ,筛选板栗品种 (因素 A)、配方施肥 (因素 B)、喷施微量元素 (因素 C)以及喷施次数 (因素 D) 4个因素 ,每个因素设计 3个水平进行试验 .结果表明 :品种和喷施次数对促进板栗雌花芽分化无显著影响 ,配方施肥、喷施微量元素对促进板栗雌花芽分化有显著影响 ,其中 ,配方施肥以每株施 0 .37kg尿素 +0 .64 kg过磷酸钙 +0 .2 5 kg氯化钾效果最好 ,喷施微量元素以喷 0 .2 %的硼 +0 .To promote the differentiation of Castanea mollissima Blume female buds so as to increase its fruit production, three parallel experiments were conducted for each of the four factors, namely, species selection (Factor A), recipe fertilization (Factor B), microelement spraying (Factor C) and spraying frequency (Factor D). The results show that species and spraying frequency have no obvious influence upon promoting the differentiation while recipe fertilization and microelement spraying do have an obvious influence. The optimal recipe for fertilization is to apply per tree 0.37 kg of urea + 0.46 kg of calcium superphosphate + 0.25 kg of potassium chloride and the optimal microelements for spraying per tree are 0.2% of boron +0.3% of potassium bihydrogen phosphape.
