不同施肥模式对盆栽辣椒产量及营养元素含量的影响

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。

Effects of Different Fertilization Modes on Yield and Nutrition Elements Content of Potted Pepper(Capsicum frutescens L.)

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.
