摘要: 采用三因素五水平二次回归正交旋转组合设计的方法,研究不同密度(x1)、氮肥(x2)及硼肥(x3)对凤紫运1号紫色辣椒产量的影响,结果表明,三个因素线性项对辣椒产量影响为正向极显著,效应大小顺序是x2>x3>x1,二次项影响为负向极显著,顺序是x12>x32>x22,x1x3互作效应正向极显著,x1的边际效应最大。当定植密度4 123株·667m-2,氮肥40.020 kg·667m-2,硼肥1.000 kg·667m-2时产量最高,为3 206.678 kg·667m-2。综合因子频数分析表明,95%置信度下凤紫运1号产量高于2 500 kg·667m-2的高产栽培的因子优化组合为:密度3 903~4 172株·667m-2,氮肥施量31.186~36.081 kg·667m-2,硼肥施量0.724~0.880 kg·667m-2

Abstract: In order to optimize the main cultivation factors that affect the production of pepper crops, the method of three-factor five-level quadratic orthogonal rotation design was used to study the effects of different density (x1), nitrogen fertilizer level (x2) and boron fertilizer level (x3) on the yield of purple pepper Fengziyun No. 1. The results showed that under the experimental conditions, the linear effect of the three factors on the yield of pepper was positive and very significant, and x2 had the greatest impact on production, followed by x3, and x1 had the least impact. The effect of the quadratic term was negative, and x12 had the greatest impact on production, followed by x32, and x22 had the least impact. The interaction effect of x1x3 was very significantly positive, the marginal effect of x1 was the largest. When the planting density was 4 123 plants per 667m2, the nitrogen fertilizer was 40.020 kg per 667m2 and the boron fertilizer was 1.000 kg per 667m2, the fresh pepper fruit weight was the highest of 3 206.678 kg per 667m2. The results of comprehensive factor analysis showed the optimized factor combination of high yield of Fengziyun No. 1 with a yield of more than 2 500 kg per 667m2 at 95% confidence was that density 3 903-4 172 plants per 667m2, nitrogen fertilizer 31.186-36.081 kg per 667m2, boron fertilizer 0.724-0.880 kg per 667m2.

Key words: pepper, density, nitrogen fertilizer, boron fertilizer, yield
