摘要
为促进化肥在喀斯特山区的高效利用,实现化肥增效减施,为辣椒高效栽培提供最佳施肥数量、施肥比例、施肥方法的科学依据,在黔西县绿化乡中等进行田间试验,进行氮、磷、钾肥总量控制研究。结果表明:辣椒产量与氮、钾肥施用量呈正相关,与磷肥施用量相关性不明显,这可能与试验区域土壤养分含量有关。合理配套施用氮、磷、钾肥是提高辣椒产量、增加效益的有效措施,并且在生产上施肥不能只限于高产,还要考虑到经济效益。
In order to promote the efficient use of chemical fertilizers in Karst Mountainous areas,realize the synergistic effect of chemical fertilizers,and provide scientific basis for the optimal amount,proportion and method of fertilization for the high-efficient cultivation of pepper,field experiments were conducted to control the total amount of nitrogen,phosphorus and potassium fertilizers in greening township of Qianxi County.The results showed that the yield of hot pepper was positively correlated with the application of N and K fertilizers,but the correlation of P fertilizer was not obvious,which might be related to the soil nutrient content in the experimental area.Rational matching application of nitrogen,phosphorus and potassium fertilizers is an effective measure to increase the yield and benefit of hot pepper.Moreover,in production,fertilization should not be limited to high yield,but also take into account economic benefits.
