| 摘 要： | 为探究新型肥料在贵州黄壤区辣椒上的施用效果,本研究通过盆栽试验研究了普通复合肥(FHF)、保水型(BSX)、稳定性(WDX)、包膜型(BMX)缓释肥和长效氮肥(CXDF)五种新型肥料施用对贵州辣椒生长、品质及光合特性的影响,并通过相关分析明确影响辣椒产量的主导因素,以期为适宜的新型肥料品种筛选及其在辣椒种植中的推广应用提供参考依据。结果表明∶与普通复合肥(FHF)相比,施用新型肥料使辣椒株高增加0.72%~3.76%,但对辣椒茎粗影响不大。新型肥料显著提高辣椒分蘖数和产量,分蘖数和单株产量较FHF处理分别增加2.65%~19.75%和12.26%~29.77%,稳定性缓释肥(WDX)产量最高,达到300.35 g·株~(-1)。不同类型新型肥料对辣椒品质影响存在差异,与普通复合肥(FHF)相比,保水型缓释肥(BMX)可使辣椒硝酸盐含量显著降低23.93%、还原糖增加10.65%、Vc增加38.61%,长效氮肥(CXDF)处理的硝酸盐含量显著降低12.64%,稳定性缓释肥(WDX)处理的Vc含量显著增加56.21%,而包膜型缓释肥(BMX)和长效氮肥(CXDF)处理的Vc含量则明显著降低。相关分析结果表明,辣椒株高、分蘖数以及净光合速率(Pn)、胞间CO2浓度(Ci)和蒸腾速率(Tr)均与辣椒产量存在显著或极显著的线性相关,而综合考虑多个影响因子并利用逐步回归分析进行拟合后得到逐步回归分方程为Y=52.316X7-1.714X_6+640.888(X_6为胞间CO_2浓度(Ci)、X_7为蒸腾速率(Tr),相关系数r为0.924**),说明收获期辣椒叶片的胞间CO_2浓度(Ci)与蒸腾速率(Tr)对辣椒产量的影响起到了主导作用。综上所述,新型肥料对贵州典型黄壤上辣椒生长、品质以及光合特性的影响效果是显著的,综合来看以稳定性(WDX)和包膜型(BMX)缓释型的施用效果最优。
