摘要
为探索遵辣8号最佳的栽培密度和施肥量,采用4因素5水平二次回归正交旋转组合设计,研究不同密度、施氮量、施磷量及施钾量4个因素对遵辣8号产量的影响,建立产量与各因素的数学回归模型。结果表明,随着栽培密度、施氮量、施磷量、施钾量的提高,辣椒产量呈先升后降的趋势。小区产量高于7.82kg,即单产高于258.72 kg/667 m^2的最佳农艺优化栽培方案是:栽培密度9 092~9 815株/667 m^2、施氮量28.33~33.4 kg/667 m^2、施磷量13.78~16.51 kg/667 m^2、施钾量29.46~34.92 kg/667 m^2。
In order to explore the optimal planting density and fertilizer rate for a hot pepper variety Zunla 8 the 4 factor 5 level quadratic regression orthogonal rotational combining design was used to determine whether the different four elements such as planting density, N, P and K fertilizers influence the yield of the Zunla 8 in this study, set up the regression model between yield and each factor. The result indicated that the yield of Zunla 8 showed a trend of first rising and then falling, along with the increase of the planting density, N, P and K application rate. The yield was to reach over 7.82 kg, per plot, i.e. over 3 880.8 kg per hm^2, if the planting density was 136 380 to 147 225 plants per hm^2, the fertilization rate of N was 424.95 to 501.00 kg per hm^2, the fertilization rate of P was 206.70 to 247.65 kg per hm^2, and the fertilization rate of K was 441.90 to 523.80 kg per hm^2.
