Abstract Taking‘ Teluomu’ pepper as material，this paper studied the effects of 5 anti-seepage loadcarrying models on the growth and yield of pepper， and the cost of these different 5 anti-seepage load-carrying models. The results showed that anti-seepage load-carrying models had remarkable effects on plant height，stem diameter， dry matter weight， root activity and pepper yield. The yield increased by geotextile line groove processing， ordinary porous brick groove processing， plastic film line groove processing and concrete slab production slots were 17.6%， 15.1%， 8.7%， and 7.4% higher than the CK， respectively. But the yield by concrete slab production slots was reduced 19.5% than the CK. Through comparing the yield of pepper cultured in sandy soil and production cost of 5 anti-seepage load-carrying models， geotextile line groove processing， plastic film line groove processing and ordinary porous brick groove processing were suitable to be extended and applied in greenhouse cultivation in sandy soil， for their low production costs and remarkable yield increasing effects.
