缓释肥料对辣椒产量及品质的影响研究

采用田间试验的方法研究了非包膜(混合)型缓释肥料在辣椒上的应用效果,结果表明:在等氮磷钾养分量条件下,缓释肥对辣椒有一定的增产效果和改善品质效果,其中缓释肥2号作基肥一次性施用的肥效基本达到或超过常规分次施肥处理;与一次性施用普通复混肥相比,产量可增加13.7%~24.6%,辣椒单果重和维生素C含量分别提高8.0%~12.4%和7.7%~8.4%,而对干物重和水溶性糖含量的影响不明显。初步表明缓释肥2号在辣椒生产上应用,肥效较显著,且可比常规栽培减少追肥次数,具有一定的应用前景。

Effects of slow-release fertilizers on yield and quality of pepper (Capsicum annuum L.)

A two-year field trial was conducted to evaluate the agronomic effects of two types non-coated slow-release nutrient bulk blend fertilizers on pepper(Capsicum annuum L.).Compared to basal application of conventional bulk blend fertilizers when applied at the same rates of N,P and K,basal application of non-coated slow-release nutrient fertilizer(No.2) increased the pepper yields from 13.7% to 24.6%,fresh fruit weight from 8.0% to 12.4%,and ascorbic acids from 7.7% to 8.4%.However,no differences were observed in dry biomass of fruit weight and water soluble sugars among the fertilizers.The results of this study indicate that non-coated slow-release nutrient bulk blend fertilizers were similar to or better than the conventional bulk blend fertilizers in increasing fruit yields and improving fruit quality of pepper,with the slow-release nutrient fertilizer(No.2) being the most effective among the fertilizers evaluated,suggesting that it may have potential as a commercial fertilizer.
