中文摘要：

通过盆栽大方线辣椒，研究了土壤水分含量与施氮量对辣椒果实产量和品质的影响。结果表明，土壤水分含量和施氮量对产量影响显著，其中W2N2（土壤水分下限为60％Q，0．2gN／kg干土）产量最高；同一土壤水分含量，施氮能显著的增加辣椒素、维生素C、干物质和可溶性糖等物质含量，但施氮过多，辣椒素、维生素C含量下降；同一施氮量，土壤水分含量下降辣椒素、维生素C含量显著增加。综合来看，W2N2产量最高，品质较好。

英文摘要：

Effects of nitrogen fertilizer rate and soil water content on yield and quality of hot pepper were studied in pot-cultured Dafang hot pepper.The results indicated that there was a significant effect of nitrogen fertilizer rate and soil water content on the yield.W2N2 （soil water lower limit 60%Q,0.2gN/kg dry soil） obtained the highest yield. Capsaicin content,vitamin C content,dry matter content and soluble sugar content showed significant positive correlation with nitrogen fertilizer rate at the same soil water content levels,but capsaicin content and vitamin C content declined with too much nitrogen fertilizer rate. Capsaicin content and vitamin C content increased with the decline of soil water content under the same nitrogen fertilizer rate conditions.In general,W2N2 makes highest yield and good quality.
