以‘佳西娜74-112’番茄自根嫁接植株及其与8种砧木嫁接植株为试材,研究盐胁迫下不同砧木对番茄生长、产量、品质、钾钠离子吸收与分配、光合作用等的影响,采用隶属函数法进行综合评价。结果表明,虽然盐胁迫降低了生长势和产量,但却显著提高了果实品质。嫁接植株生长势、产量、品质和耐盐性因砧木不同而显著不同。采用‘西方番茄砧木’嫁接进行耐盐栽培,比对照条件下自根嫁接番茄产量降低32.3%,但比盐胁迫栽培的自根嫁接番茄产量提高37.7%,且对果实品质的负面影响相对较小,表现出最强的综合优势。采用隶属函数法将多项指标进行综合排序,提出了一套可应用于番茄耐盐砧木筛选的分析流程,有望为盐碱地土壤的综合开发利用提供参考。
The self-rooted grafted tomato plants and their grafted plants with eight kinds of rootstocks were used as experimental materials to study the effects of different rootstocks on the growth, yield, quality, absorption and distribution of potassium and sodium, and photosynthesis of tomato under salt stress The use of membership function method for comprehensive evaluation. The results showed that although salt stress reduced the growth vigor and yield, the fruit quality was significantly improved. Grafting plant growth potential, yield, quality and salt tolerance significantly different due to different rootstocks. Compared with the control, the yield of self-rooted tomato decreased by 32.3% compared with that of the control, but the yield of self-rooted tomato increased by 37.7% and the negative impact on the quality of the fruit was relatively small , Showing the strongest comprehensive advantage. A membership function method was used to rank a number of indexes comprehensively. A set of analysis flow that could be applied to screening salt-tolerant rootstocks in tomato was put forward, which is expected to provide a reference for the comprehensive development and utilization of saline-alkali soil.
