摘要

目的:探究氮磷钾配施对青海枸杞子产量和药用成分的影响,以期为青海枸杞子的施肥提供依据。方法:以六年生枸杞树为试验材料,采用"3414"实验设计,研究在膨果期氮磷钾配施对青海枸杞子产量和药用成分的影响。结果:氮磷钾配方施肥方案中产量、百粒质量、多糖含量、β-胡萝卜素所对应的较佳方案是N_1P_2K_1、N_2P_1K_2、N_1P_2K_2、N_2P_3K_2。结论:氮磷钾配施对枸杞子百粒质量的影响依次为磷>钾>氮;氮磷钾配施对枸杞多糖含量的影响依次为钾>磷>氮;氮磷钾配施对β-胡萝卜素含量的影响依次为磷>氮>钾;氮磷钾配施对枸杞子产量的影响无最大值,因此在下一步研究中可扩大其范围,并为下一步研究提供数据支撑。
        Objective:To explore the effect of N,P and K application amount and proportion on the yield and medicinal ingredients of wolfberry in Qinghai and provide a basis for standardized fertilization of wolfberry in Qinghai.Methods:Taking wolfberry of six years as experimental material,N,P,and K were designed with "3414" design to study the effects of nitrogen,phosphorus and potassium application amount and proportion on the yield and medicinal ingredients of fruiting period of wolfberry in Qinghai.Results:The preferred schemes for yield,100-grain weight,polysaccharide content,and β-carotene in the NPK formula fertilization scheme are N_1P_2K_1,N_2P_1K_2,N_1P_2K_2,and N_2P_3K_2.Conclusion:The effect of NPK application amount and proportion on the 100-grain weight of wolfberry was phosphorus>potassium>nitrogen.The effect of NPK application amount and proportion on glutinous polysaccharide was potassium>phosphorus>nitrogen.The effect of NPK application amount and proportion on β-carotene was potassium>phosphorus>nitrogen.The effect of NPK application on the yield of wolfberry has no maximum value,so it can expand its scope in the next study and provide data support for the further study.
