采用田间试验的方法研究了非包膜(混合)型缓释复混肥在辣椒上的应用效果。结果表明,等量的氮磷钾养分条件下缓释复混肥比普通复混肥有一定的增产和改善品质的效果。其中缓释肥2号的增产效果明显,一次基施的肥效达到常规分次施肥,比普通复混肥一次施用增产13.7%～24.6%。施用缓释复混肥还可提高氮肥利用率,其中缓释肥2号的农学生产率比复混肥一次施用相对增加61.2%～68.8%,比常规分次施肥相对增加4.0%～11.1%;氮素吸收利用率比普通复混肥一次施用处理增加10.29%～10.89%,比常规分次施肥增加3.79%～5.85%。
A field experiment was carried out to study the application effect of non-coated (mixed) slow release compound fertilizer on pepper. The results showed that the same amount of NPK nutrients under the conditions of slow release compound fertilizer than ordinary compound fertilizer have some yield and improve quality results. Among them, slow-release fertilizer 2 has a significant stimulation effect. The first-time application of fertilizer achieves the conventional graded fertilization, which increases 13.7% ~ 24.6% compared with that of common compound fertilizer. Application of slow-release compound fertilizers also increased nitrogen use efficiency, of which slow-release fertilizer 2 agronomic productivity than the first application of compound fertilizer relative increase of 61.2% to 68.8%, compared with the conventional fractional fertilizer relative increase of 4.0% to 11.1%; nitrogen Superabsorbent utilization rate increased by 10.29% -10.89% compared with that of common compound fertilizer, and increased by 3.79% -5.85% compared with conventional fraction fertilization.
