| 摘 要： | 在甘肃干旱内陆气候条件下,以色素辣椒‘美国红’为试验材料,研究了膜下滴灌方式下6种灌溉定额(170、195、220、245、270、295 m3.667 m-2)对土壤含水量、辣椒株高、茎粗、地上部干质量和产量的影响.结果表明:在辣椒的整个生育期内,灌水定额220 m3.667 m-2处理的土壤含水量最低,膜下土壤含水量保持在16.3%~19.8%之间,膜间土壤含水量保持在17.0%~18.9%之间;并且处理的株高、茎粗、地上部干质量、产量、单株产量均优于其他处理.结果盛期(8月27日),220 m3.667 m-2灌水定额处理分别较170、195、270、295 m3.667 m-2处理的株高高17.4%、13.5%、2.2%和8.6%,茎粗高6.9%、12.0%、8.9%和9.1%,地上部分干质量高1.8%、19.5%、21.3%和19.9%,667 m2产量高15.0%、11.1%、6.7%和26.1%,单株产量高10.0%、7.8%、6.7%和4.4%.

| Abstract: | Under arid climate conditions of Gansu,pigment peppers(cv.'American red') were used as experimental materials to study the effects of drip irrigation under six kinds of quota(170,195,220,245,270,295 m3·667 m-2) on soil moisture,plant height,stem diameter,shoot dry weight and yield.The results showed that the irrigation quota at 220 m3·667 m-2 had the lowest soil moisture during the growth,soil water content ofunder and between the covered films maintained at 16.3 %~19.8 % and 17.0 %~18.9 % respectively.The treatment also had the maximum plant height,stem diameter,shoot dry weight,yield per 667 m2 and yield per plant.It is suggested that the treatment at 220 m3·667 m-2 could be an appropriate irrigation quota for pigment pepper production in Liangzhou District of Wuwei. |
