冬瓜施用不同缓释(控释)肥料的产量和质量效应

摘要/Abstract

摘要： 采用田间小区试验和应用示范相结合，研究了3种天然植物素等材料包膜缓释肥和2种高分子材料包膜控释肥对冬瓜产量和质量的影响。2年试验结果表明，在相等氮磷钾施用量条件下，缓释肥1号的增产效应显著优于其它处理，平均较常规分次施肥增产15.6%；而且，缓释肥1号处理还显著提高或趋于提高冬瓜的干物率、维生素C和可溶糖等质量指标。3个示范结果表明，缓释肥1号与常规分次施肥比较，平均增产7.61%，分别减少氮磷钾养分用量6.73%，71.1%和46.0%，降低用肥成本40.0%

Abstract: Field trials and demonstrations were conducted to study the effects of 3 slow-release fertilizers (SRF), coated with natural vegetal materials, and 2 controlled-release fertilizers (CRF), coated with polymer materials, on yield and quality of wax gourd. Results of 2 years illustrated that yield-increasing effect of the SRF1 was significantly superior to other treatments, averaging in 15.6% higher yield over the treatment of normal splitting fertilization (NSF) under the same NPK rates. In addition, the SRF1 trended to improve quality of wax gourd through relatively increasing dry matter rate and concentrations of vitamin C and soluble sugar. In comparison to farmers’ NSF, the SRF1 resulted in significantly hiher yields in 2 of 3 demonstrations, with yield increase by 7.61% in average, meanwhile, reduced NPK application rates respectively by 6.73%, 71.1%, 46.0%, and fertilization cost by 40.0%.
