黄腐酸型套餐肥在辣椒上的应用效果研究

Application Effect Study of Fulvic Acid Package Fertilizers on Pepper

为筛选适合辣椒生长的黄腐酸型套餐肥,提高辣椒产量和品质,研究了不同黄腐酸型套餐肥在辣椒上的施用效果。结果表明,与常规施肥相比,不同黄腐酸型套餐肥均能促进辣椒生长,增加辣椒株高和茎粗,提升辣椒果实品质,提高辣椒产量。套餐肥T2处理[黄腐酸复合肥1(22-18-5)+黄腐酸复合肥3(18-8-18)]比常规施肥处理的辣椒株高、茎粗增加29.8%、11.1%,Vc含量显著增加89.2%,增产率达到25.0%。因此,套餐肥T2处理在辣椒上的效果最佳,"二荆条"辣椒品种推荐生长前期施用黄腐酸复合肥1(22-18-5),生长后期施用黄腐酸复合肥3(18-8-18)。

In order to screen the favorite fulvic acid package fertilizers for improvement the growth,yield and quality of pepper,the effects of different fulvic acid package fertilizers on pepper were studied.The results showed that compared with conventional fertilization,different fulvic acid package fertilizers had positive effects on the pepper growth,plant height,stem diameter,fruit quality and the yield.T2[fulvic acid compound fertilizer 1(22-18-5)+fulvic acid compound fertilizer 3(18-8-18)]increased plant height,stem diameter and the yield by 29.8%,11.1%and 25.0%,respectively.Vc content significantly increased by 89.2%.Indicating that T2 was the best fulvic acid package fertilizers for the pepper.Fulvic acid compound fertilizer 1(22-18-5)was suitable in early growth stage,while fulvic acid compound fertilizer 3(18-8-18)in late growth stage for“Erjing Tiao”pepper variety.
