摘要： 为提高板栗的产量，对圈肥、尿素、过磷酸钙、氯化钾、磷酸二氢钾等肥料，运用二次旋转正交组合设计，开展综合配套的施肥田间试验。从而建立相应的五元二次回归数学模型，获得板栗丰产的最优化施肥方案是在上一年果实采收后施圈肥12.64~13.75kg；在4月份对每株树木的结果母株喷施1.56%~1.77%浓度的磷酸二氢钾；在7月份对每株树木施尿素0.27~0.29kg、过磷酸钙0.35~0.40kg、氯化钾0.21~0.23kg

Abstract: The quadratics rotary orthogonal combination design was used to conduct field experiment of integrated balanced of yard manure, urea, calcium superphosphate, potassium chloride and potassium dihydrogen phosphate fertilizer in order to increase the yield of Chinese chestnut．Five quadratic regression mathematical models were established. Some conclusions were drawn from the model: Optimization fertilization program for increase the field of Chinese chestnut are applied yard manure 12.64~13.75 kg after harvest in fruit at previous year. Potassium dihydrogen phosphate 1.56%~1.77% on bearing base shoots of per tree was sprayed in April. Urea 0.27~0.29 kg, calcium superphosphate 0.35~0.40 kg, potassium chloride 0.21~0.23 kg to per tree were applied in July
