腐殖酸液体肥对贵州鲜食辣椒生物效应及肥料利用率的影响

Effects of Humic Acid Liquid Fertilizer on Biological Effect and Fertilizer Utilization Efficiency of Pepper in Guizhou Province

以‘黔椒11号’辣椒为试材,采用田间试验法,研究了腐殖酸液体对贵州鲜食辣椒产量、品质、养分积累和肥料利用率的影响,探明腐殖酸液体肥对贵州鲜食辣椒生物效应和肥料利用率的影响,以期为腐殖酸液体肥在贵州辣椒生产中的应用推广提供参考依据。结果表明:与FP处理相比,CSF、CLF1、CLF2处理可以显著增加辣椒鲜产水平,增幅分别为6.12%、9.12%、2.30%,但是LF处理则出现降低,降幅为6.99%。CSF、CLF1、CLF2处理的蛋白质和维生素C含量均有一定的提升,但是LF处理的蛋白质和维生素C含量则出现降低。从肥料利用率看,CSF、CLF1、CLF2和LF处理可以提高氮肥和磷肥的农学效率和表观利用率,其中CLF1处理的肥料表观利用率最优,氮、磷、钾肥表观利用率分别为39.01%、14.68%、46.54%。在贵州鲜食辣椒种植栽培中,采用复合肥作基肥、腐殖酸液体肥作追肥的施肥方式可以实现辣椒增产提质以及肥料减量增效的目的。

Taking‘Qianjiao No.11’peper as test material,the effects of humic acid liquid on yield,quality,nutrient accumulation and fertilizer use efficiency of fresh pepper‘Qianjiao No.11’in Guizhou were studied by field experiment.The effect of humic acid liquid fertilizer on the biological effect and fertilizer utilization rate of fresh pepper in Guizhou Province was explored,in order to provide a reference for the application of humic acid liquid fertilizer in pepper production in Guizhou Province.The results showed that compared with FP treatment,CSF,CLF1 and CLF2 treatments significantly increased the fresh yield of pepper by 6.12%,9.12%and 2.30%,respectively.But LF treatment decreased by 6.99%.The protein and vitamin C contents of CSF,CLF1 and CLF2 treatments were increased to some extent,but they were decreased in the LF treatment.From the fertilizer use efficiency,the agronomic efficiency and apparent use efficiency of nitrogen and phosphorus could be improved in the CSF,CLF1,CLF2 and LF treatments,which the CLF1 treatment was the best.The apparent use efficiency of nitrogen,phosphorus and potassium were 39.01%,14.68%and 46.54%respectively in the CLF1 treatment.In the cultivation of fresh pepper in Guizhou,the application of compound fertilizer as base fertilizer and humic acid liquid fertilizer as topdressing can not only increase the yield and quality of pepper,but also reduce and increase the efficiency of fertilizer.
