摘　　要：以温室无土基质盆栽甜椒（Capsicwn frutescens L．）为试验材料，研究了不同水分处理对甜椒生长及其产量的影响，以确定甜椒生长的最佳基质含水量，为今后的甜椒生产合理灌溉提供科学的参考依据。结果表明：在全生育期，适宜基质含水量（60％～70％）下，甜椒生长势强、干物质积累多、单果重，产量高。较低（50％-60％）或较高含水量（70％～80％）均不能达到甜椒增产的目的。较高水分含量虽有利于植株生长，但结果盛期座果率低，产量低。In order to choose the optimal substrates irrigation for the growth of soilless potted sweet pepper in moisture and offer the scientific reference of accurate greenhouse. The effects of different water treatments on growth and yield of sweet pepper was studied. The results showed that sweet pepper has a good single fruit weight, more dry matter and higher yield under the appropriate moisture（ 60% -70%） during the whole growth period. The less or the more substrates moisture all cannot achieve a higher yield.The higher moisture（70% - 80% ） is better for plants to grow but not for yield.
