摘　　要：为了进一步探究不同滴灌灌溉量对辣椒农艺性状的影响,进一步筛选出最佳的滴灌处理方案,在广西钦州市灌溉试验站种植基地开展试验,分析了不同灌溉量对辣椒农艺性状、产量和水分利用效率的影响。结果表明,灌溉量为1940 m^(3)/hm^(2)时,膜下滴灌种植方式下软皮杭椒的生长状况最好,产量最高为39335.55 kg/hm^(2);同时植株株高和茎粗值均大于其它处理,随着灌溉量的减少,辣椒的农艺性状会呈现出逐渐下降的趋势,同时辣椒的产量也会逐渐下降。综合考量作物产量、水分的利用效率,膜下滴灌种植模式下,灌溉量应为1920 m^(3)/hm^(2)。In order to study the effect of drip irrigation volume on the agronomic traits of chili pepper,so as to select the optimum drip irrigation scheme,experiments were carried out at the planting base of Irrigation Test Station of Qinzhou City in Guangxi.Analysis was made on the effects of irrigation volume on the agronomic traits and yield of chili pepper as well as water use efficiency.The results of study demonstrate that when the irrigation volume is 1940 m^(3)/hm^(2),the growth of soft skin hot green pepper with under-film drip irrigation is the best with the maximum yield of 39335.55 kg/hm^(2);and the plant height and stem diameter being both greater than that under conditions of other irrigation schemes.With the decrease of irrigation volume,the agronomic traits and yield of chili pepper show a gradual decline trend.Taking into account crop yield and water use efficiency,for under-film drip irrigation planting mode,the irrigation volume should be1920 m^(3)/hm^(2).
