摘要
【目的】探究不同缓释肥配施对荞麦产量和品质的影响,找出最经济的缓释肥和有机肥配施比例,为缓释肥在荞麦种植中的推广提供依据。【方法】以有机肥为基肥,设置5个缓释肥处理,测定叶绿素含量,收获时测定荞麦产量及可溶性糖、蛋白质、芦丁和总黄酮含量等各项品质指标。【结果】不同的缓释肥配施对叶绿素含量影响呈现T4>T3>T2>T1>CK的趋势,荞麦的产量呈现T4>T3>T2>T1>CK的趋势;在品质方面,对可溶性糖含量、芦丁含量和总黄酮含量呈现T4>T3>T2>T1>CK的趋势。【结论】处理T3和处理T4对荞麦叶绿素、荞麦产量及可溶性糖、蛋白质、芦丁和总黄酮含量的促进效果为最佳,且以处理T4(缓释肥∶有机肥=1∶2)的比例施用,可以明显地提高荞麦的产量和改善荞麦的品质。
【Objective】To explore the effects of different slow-release fertilizers on the yield and quality of buckwheat,to find the most economical ratio of slow-release fertilizers and organic fertilizers,and provide a basis for the promotion of slow-release fertilizers in buckwheat planting industry.【Methods】Using organic fertilizer as the base fertilizer,5 slow-release fertilizers treatments were set up to determine the chlorophyll content,and the buckwheat yield and soluble sugar,protein,rutin,total flavonoids content and other quality indicators were measured at harvest.【Results】The effect of different slow-release fertilizers on the chlorophyll content showed a trend of T4>T3>T2>T1>CK,and the yield of buckwheat showed a trend of T4>T3>T2>T1>CK;in terms of quality,the soluble sugar content,rutin content and total flavonoid content showed the trend of T4>T3>T2>T1>CK.【Conclusion】Treatments T3 and T4 have the best promotion effect on buckwheat chlorophyll,buckwheat yield,soluble sugar,protein,rutin and total flavonoids content,and the treatment T4(slow-release fertilizer∶organic fertilizer=1∶2)proportional application couldan significantly improve the yield and quality of buckwheat.
