摘要
为探索适宜辣椒的施肥量,以"遵椒4号"为材料,采用四因素(微量元素、氮、磷和钾)五水平二次正交旋转组合设计,按标准试验布置小区,36处理,以小区产量Y为因变量,微量元素(X1)、氮(X2)、磷(X3)、钾(X4)四元素为自变量,进行多元分析和主效应分析。结果表明四因素对小区产量的大小为氮>钾>磷>微量元素,二次项:钾>氮>磷>微量元素,说明钾是提高辣椒产量的重要因素,氮和磷对产量也有较大影响。据此推导最优施肥方案为,N:4.14~5.98 kg/667m2;P2O5:6.4~9.6 kg/667m2;K2O:18.6~21.6 kg/667m2;微量元素:1.5~2.5 kg/667m2。
Based on the four factors (trace elements, nitrogen, phosphorus and potassium) five-level quadratic orthogonal rotation design, according to the standard test layout of the district, 36 treatment, the yield Y as the dependent variable, trace elements (X 1), nitrogen (X 2), phosphorus (X 3) and potassium (X 4) four elements as independent variables,to annalyze multivariate and main effect for explore appropriate fertilizer rates of hot pepper. The results showed that the effects of four factors on the yield were: nitrogen 〉 potassium〉 phosphorus〉 trace element, Quadratic Terms:potassium〉 nitrogen〉 phosphorus〉 trace element. According to above results, the optimal fertilization scheme was as follows: P 2O 5: 6.4 - 9.6 kg / 667m 2; K 2O: 18.6 - 21.6 kg / 667m 2; trace elements: 1.5 - 2.5 kg / 667m 2.
