不同种植密度和氮磷钾施肥量对辣椒产量的影响
|
摘要
以"遵椒4号"为材料,开展密度、氮磷钾施用量与辣椒产量的关系试验,为辣椒最优种植方案提供参考。采用四因素(密度、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个处理,以小区产量Y为因变量,密度(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,发现:四因素对小区产量影响的大小依次为氮>钾>密度>磷,二次项:钾>磷>氮>密度,说明磷和钾对产量有较大影响。拟合最优栽培方案为:N:7.13~9.43 kg/667m2;P2O5:6.56~9.76 kg/667m2;K2O:17.1~18.9 kg/667m2;密度:7000~7302株/667m2。
A chili variety " Zunjiao No. 4" selected as the test material to research the relationship among the planting density,proper amount of applied nitrogen,phosphate,potassium and the chili yield,which aimed to provide reference for the optimal fertilization scheme of pepper. Based on the four factors( density,nitrogen,phosphorus and potassium) five-level quadratic orthogonal rotation design,according to the standard test layout,36 treatments,the cell yield Y as the dependent variable,density( X1),nitrogen( X2),phosphorus( X3,potassium( X4) four elements as independent variables,to analyze multivariate analysis and main effect analysis,The results showed that the effects of four factors on the yield were: nitrogen > potassium > density > phosphorus,Quadratic Terms: phosphorus > potassium > nitrogen > density,indicating that phosphorus and potassium had a greater effect on yield. On the basis of this,the optimal fertilization scheme was as follows: N: 7. 13 ~ 9. 43 kg/667 m2; P2 O5: 6. 56 ~ 9. 76 kg/667 m2; K2 O:17. 1 ~ 18. 9 kg/667 m2; density: 7000 ~ 7302 plants/667 m2.
