不同施肥模式对盆栽辣椒产量及营养元素含量的影响

摘要

[Objective] The purpose was to compare the effects of six fertilization modes on yield of potted pepper and its N, P and K contents. [Method] Six fertilization modes were as follows: vegetable garden experimental formula nutrient solution(CK) ; controlled release fertilizer 14-14-14; controlled release fertilizer 14-14-14 + water-soluble fertilizer 15-5-15Ca5Mg2; water-soluble fertilizer 15-5-15Ca5Mg2; water-soluble fertilizer 20-20-20; organic fertilizer + water-soluble fertilizer 20-20-20. [ Result] The results showed that using fertilization modes of organic fertilizer + water-soluble fertilizer 20-20-20, water-soluble fertilizer 20-20-20, and controlled release fertilizer 14-14-14 + water-soluble fertilizer 15-5-15Ca5Mg2 obtained higher yield. N, P and K contents in potted pepper increased gradually with fertilization level rising, meanwhile, there were interaction effect and antagonism among them. [ Conclusion] The fertilization mode using controlled fertilizer and water soluble fertilizer is more suitable for family potted pepper plantation.%[目的]比较6种不同施肥模式对盆栽辣椒(Capsicum frutescens L.)产量和辣椒N、P和K含量的影响.[方法]施肥模式共分6种:CK,园试配方营养液；14-14-14缓释肥；14-14-14缓释肥+15-5-15Ca5Mg2水溶性肥；15-5-15Ca5Mg2水溶性肥；20-20-20水溶性肥；有机肥+ 20-20-20水溶性肥.[结果]利用有机肥+20-20-20水溶性肥、20-20-20水溶性肥、14-14-14缓释肥+15-5-15Ca5Mg2水溶性肥施肥模式,都能得到比较高的产量.辣椒果实内N、P和K含量随着施肥水平的升高而逐步升高,同时N、P和K元素间也存在互作效应和拮抗作用.[结论]相比较而言,14-14-14缓释肥+15-5-15Ca5Mg2水溶性肥施肥模式,采用14-14-14缓释肥,干净、卫生,肥效长,配合水溶性肥料,更加适合现代家庭.
