摘　　要：为研究暗管排水对番茄生长和品质的影响,在盐碱土中设有不同埋深与间距的暗管,并对番茄生长与果实品质进行了观测。结果表明:暗管排水处理后的耕层土壤对改善番茄的外观,增加株高有积极作用,且暗管排水能有效改善番茄品质,各处理VC含量分别比对照高10.25%、-2.21%、14.78%和14.40%,可溶性糖含量比对照高7.56%、5.40%、11.02%和4.54%,糖酸比分别比对照高12.78%、7.30%、14.47%和12.08%。结论:暗管的使用可增加番茄可溶性蛋白含量,降低硝酸盐含量;且以8m间距和0.6m埋深的暗管效果较好。To understand the effects of subsurface drainage system on tomato growth and quality,the saline soil was treated by two subsurface drainage designs with different depth and space,meanwhile,the growth of tomato plants,and the quality of tomato fruits were observed in the experiment.The results showed that the drainage-treated soil made the positive difference on the tomato appearance and the plant height.And the subsurface drainage system had obvious advantage in improving the tomato quality,the increasing rate of Vc content of T1,T2,T3 and T4（compared with CK） was 10.25%,-2.21%,14.78% and 14.40% separately;The increasing rate of soluble sugar content of T1,T2,T3 and T4 was 7.56%,5.40%,11.02% and 4.54% separately;And the sugar/acid value of T1,T2,T3 and T4 was 12.78%,7.30%,14.47% and 12.08% higher than that of CK;Besides,the nitrate content in the tomato fruit was controlled to some extent,and the content of the soluble protein was slightly increased.According to the analysis,drain space 8 m and drain depth 0.6 m was the recommended parameters.
