| 摘 要： | 本试验采用二次通用旋转组合设计,通过计算机分析,建立了氮磷钾与大棚青椒早期产量及总产量的数学模型。初步揭示了在本试验条件下,氮磷钾对大棚青椒产量形成的影响规律及其边际效应,探讨了氮磷钾之间的交互作用。结果表明氮对青椒产量影响最大,钾最小,前期磷钾有显著的交互作用。讨论了最佳氮磷钾配比及适宜范围。

| Abstract: | By means of guadratic rotational combination design, a three-factor (N.P.K) experiment was conducted in a plastic greenhouse. With the aid of computer, guadratic regression models demonstrating the relationship between N.P.K and yielel were established. The effect of N.P.K on sweet pepper, its marginal effect and interactions were studied. The result indicated that N had bigger effect on yiecel formation of sweet pepper. The optimum compound also was discussed. |
