摘　　要：为研究北方越夏茬大棚甜椒高产配套栽培技术,以甜椒"红美人"为试材,采用L16(43)正交实验设计,比较不同水平密度(667 m^2密度为3 000~3 900株)、苗龄(50~71d)、追肥(667m^2施肥0~40kg)处理对甜椒生长、产量及经济效益的影响。结果表明:影响甜椒不同性状的主导因子各不相同,苗龄对植株前期生长具有显著影响,对果实性状及产量影响不显著,57d苗龄最适于植株生长;密度及追肥量对单果质量、坐果总数、产量具有显著或极显著影响,单果质量最佳组合为667 m^2栽植密度3 300株、50d苗龄、追肥40kg),坐果数最佳组合为667m^2栽植密度3 600株、57d苗龄、追肥30kg。产量最佳组合为667m^2栽植密度3 600株、50d苗龄、追肥30kg。通过综合分析得出,该试验条件下甜椒获得最高产量及经济效益的组合为667m^2栽植密度3 600株、57d苗龄、追肥30kg。To screen the high yield techniques for the new cultivar Capsicum annuum L. Hongmeiren over summer cultivation in plastic greenhouse,the effect of planting densities（667 m2 planling density 3 000--3 900 plants）, seedling age （50--71 days）and 667 m2 fertilizing quantity（0--40 kg）on the growth, yield and economic benefits were analyzed through L16（4a） orthogonal test. The results indicated that morphological and fruit characteristics of sweet pepper had different influencing factors. The variation ages of sweet pepper seedlings had significant effect on vegetative growing stage and had no significant effect on the fruit characteristics and yield. It was recommended that the age of sweet pepper seedlings was 57 days. The plant density and fertilizer levels had significantly affected fruit setting（FS） ,mean fruit weight （MFW） and yield of sweet pepper. The highest MFW was obtained by treatment of 667 me planting density 3 300 plants; seedling age, 50 days; 667 me fertilizing quantity, 40 kg. The highest FS was obtained by treatment of 667 mz planting density 3 600 plants; seedling age, 57 days; 667 m2 fertilizing quantity, 30 kg. The highest yield of sweet pepper was obtained by treatment of 667 m2 planting density 3 600 plants; seedling age, 50 days; 667 m2 fertilizing quantity, 30 kg. Based on these results, the optimal combination was 667 m2 planting density 3 600 plants; seedling age 57 days;667 m2 fertilizing quantity 30 kg.
