摘要 水资源短缺是一个严重的环境和农业问题，西北地区广泛使用含盐地下水来弥补淡水短缺。在盐碱化严重的民勤绿洲，通过露地试验，建立了适合樱桃番茄的咸水灌溉方案。该实验有四种处理，包括整个作物季节的淡水或盐水灌溉（对照，C，T3），间伐后50天的淡水/盐水灌溉变化（DAT 50，T1）以及DAT 50（T2）的盐水/淡水灌溉变化。测定番茄的叶面积指数（LAI）、光合速率（Pn）、蒸腾速率（Tr）、叶干物质（LDM）、茎干物质（StDM）、产量、市售果实和总可溶性固形物（TSS）。盐水灌溉，无论时间如何，都显着降低了最大 LAI、LDM 和 StDM、Pn、Tr 和气孔导度，但显着提高了水分利用效率。 T2 中最大 LAI、LDM 和 StDM 的降低低于 T1 和 T3。 T2和T3的收获指数(HI)和TSS高于T1和C。适销果在T2没有显着变化，但在T1和T3显着下降。不降低产量的最大饱和土壤电导率（耐盐阈值）为3.69 dS m−1。土壤盐分超过阈值每增加1个单位，番茄总产量将下降9.85%。 T1和T3处理的最终产量分别显着降低了24.6%和23.1%。研究结果表明，在民勤绿洲等缺水地区，樱桃番茄种植应提倡50天前用盐水灌溉，50天后用淡水灌溉。
ABSTRACT Water shortage is a serious environmental and agricultural problem and saline underground water has been widely used to make up the fresh water shortage in northwestern China. An open-field experiment was conducted to establish a proper irrigation scheme with saline water for cherry tomato in the Minqin oasis, where very severe salinization occurs. The experiment had four treatments including fresh or saline irrigation over the crop season (control, C, T3), fresh/saline-water irrigation change on days after thinning 50 (DAT 50, T1) and saline/fresh irrigation change on DAT 50 (T2). Leaf area index (LAI), photosynthesis rate (Pn), transpiration rate (Tr), leaf dry matter (LDM), stem dry matter (StDM), yield, marketable fruit and total soluble solids (TSS) of tomato were measured. Saline irrigation, irrespective of the timing, significantly decreased maximum LAI, LDM and StDM, Pn, Tr and stomatal conductance but significantly stimulated water use efficiency. The reduction in maximum LAI, LDM and StDM was lower in T2 than in T1 and T3. Harvest index (HI) and TSS were higher in T2 and T3 than in T1 and C. Marketable fruit had no significant change in T2 but significantly declined in T1 and T3. Maximum saturated soil conductivity without yield reduction (the salt tolerance threshold) was 3.69 dS m−1. Total yield of tomato would decrease by 9.85% with one unit increase of soil salinityhigher than the threshold. Final yield significantly reduced by 24.6% and 23.1% in T1 and T3 treatments, respectively. Our results suggest that irrigation with saline water before DAT 50 and fresh water after DAT 50 should be advocated for cherry tomato plantation in water-scarce areas like the Minqin oasis.
