中文摘要	为揭示滴灌水分亏缺对辣椒营养品质及产量的影响,以陇椒6号为对象,在辣椒苗期分别施加轻度(65%~ 75%田间持水量) 、中度(55% ~ 65%田间持水量)和重度水分调亏(45% ~ 55%田间持水量),在盛果期和后果期分别施加轻度水分亏缺,以全生育期充分供水(75%~ 85%田间持水量)为对照,分别测定各水分处理辣椒青果营养品质(VC质量比、可溶性糖、可溶性蛋白和可溶性固形物质量比)和产量.结果表明:在辣椒苗期进行不同程度的水分调亏对辣椒青果营养品质(VC、可溶性固形物、可溶性固形物和可溶性蛋白质量比)影响不具有统计学意义(P> 0.05);结果盛期轻度水分调亏可提高第二次收获的辣椒青果VC质量比7.8%~ 9.1%,提高可溶性糖9.8%~10.6%,提高可溶性固形物4.2%~ 4.7%,提高蛋白质质量比9.4%~ 10.4%.苗期重度水分调亏降低VC质量比2.2%.由此得出:结果盛期轻度水分调亏可以整体提高辣椒第二次收获的营养品质.苗期轻度水分调亏产量最高,为36 107.61 kg/hm~2.
英文摘要	To reveal the response of the yield and quality of pepper under water deficit of irrigation, taking the pepper variety Long Jiao 6 as testing sample,there levels of water stress,i. e.,mild (65%-75% FC),moderate(55%-65% FC) and severe(45%-55% FC) were applied at the seedling stage of pepper,and mild water stress was composed at the full fruit stages and later fruiting stages, with the treatment of full water supply (75% - 85% FC) during the whole pepper growth stage as control. Various water treatments pepper fertility final quality index (VC content,soluble sugar content, soluble solids content and soluble protein content) and yield were determinated. The result indicates that different levels of water deficit in the seedling stage couldn't suppress the quality of pepper (P>0.05). At the full fruit stage,mild water stress increases the quality of the second harvest of pepper (VC content: 7.8%-9.1%; soluble sugar content: 9.8%-10.6%; soluble solid content: 4.2%- 4.7%; soluble protein content: 9.4%-10.4%). The severe water stress at the seedling stage decreases VC content 2.20%. It follows that at the full fruit stage,mild water stress improves overall the quality of pepper. The yield of the mild water stress at the seedling and full fruit stages is the highest,namely 36 107.61 kg/hm~2.
