摘　　要：[目的]探讨苦荞（Fagopyrum tataricum）高产栽培技术措施。[方法]采用二次回归正交旋转组合设计试验,研究种植密度（43.2万、52.5万、75.0万、97.5万、106.8万株/hm^2）、复合肥施用量（281.8、375.0、600.0、825.0、918.2 kg/hm^2）对苦荞产量的影响。[结果]种植密度和施肥对苦荞产量影响显著,都表现为低水平下呈正效应,高水平下呈负效应,并且互作效应显著。获得产量高于2 100 kg/hm2的合理取值区间为：种植密度84.50万～102.97万株/hm2,施肥320.33～505.05 kg/hm^2。建立的数学模型Y=2 208.63＋122.53X1-114.33X^2-200.91X21-205.58X22-184.85X1X2的拟合程度较好,对苦荞生产具有实际指导作用。[结论]该研究可为苦荞高产优质生产提供技术参考。The aim was to develop the high-yielding cultivation technical measures of Tartary buckwheat. [Method]The quadratic regression orthogonal rotation combination design test was used to study the effects of planting density（43. 2 × 10^4,52.5 ×10^4,75.0 ×10^4,97. 5 × 10^4,106.8 ×10^4plants /hm2） and fertilizer amount（281.8,375. 0,600. 0,825. 0,918. 2 kg/hm2） on Tartary buckwheat yield.[Result]The planting density and fertilizer amount had a significant impact on yield of Tartary buckwheat,both showed positively effect under low levels and negative effects under high levels,and the interaction effect was significant. To get the yield of over 2 100 kg /hm^2,the reasonable value range was as follows： planting density was 84. 50 × 10^4- 102. 97 × 10^4 plants /hm2,the fertilizer amount was 320. 33- 505.05 kg /hm2. The established mathematical model was Y = 2 208. 63 ＋ 122. 53X1- 114. 33X2- 200. 91X^21- 205. 58X^22- 184. 85X1X2,the fitting degree of the model for test point was better,so the model had practical guidance for Tartary buckwheat production. [Conclusion]The study provides a technical reference for high yield and good quality of Tartary buckwheat.
