摘要
为了探明缓释肥在辣椒上的用法、用量及对其产量的影响,采用田间试验方法设不同施肥处理对辣椒生长势、产量、养分利用率等进行了试验,以研究缓释肥料和氮肥抑制剂在辣椒上的应用效果。结果表明:缓释肥对辣椒生长势、VC含量有明显的促进作用,在一次性施肥的情况下能提高辣椒产量及肥料利用率;施96kg/667m2施可丰缓释肥比常规肥料增产8.51%,氮肥、磷肥和钾肥的利用率分别提高9%、10.8%和6.6%,但在过量施肥(120kg/667m2)的情况下,辣椒产量有所下降。
A field experiment was conducted to study the application effects of slow-release fertilizer and nitrogen inhibitors on pepper for exploring the effects of slow-release fertilizers on pepper production.The results showed that applying slow-release fertilizers could significantly increase the growth vigor and VC content.Meanwhile,pepper yield and fertilizer utilization rate were increased.Compared with conventional fertilizers,applying 96 kg/667m2 Shikefeng slow-release fertilizer could increase pepper yield,nitrogen utilization rate,phosphorus utilization rate,potassium utilization rate by 8.51%,9%,10.8% and 6.6% respectively.However,the pepper yield would be decreased when applied with excessive fertilizers.
