为了研究不同配方营养基质条件下，番茄穴盘苗贮运前后形态和生理指标的变化问题，以番茄‘青研番茄一号’为试验材料，采用人工模拟穴盘苗贮运环境、试验分析测定的方法，研究了6种不同营养基质配方对模拟贮运番茄穴盘苗质量保持的影响。结果表明，模拟贮运环境下，不同营养基质栽培的番茄穴盘苗叶片的叶绿素、可溶性蛋白、可溶性糖含量均呈下降趋势，但不同营养基质处理间的下降幅度不同。综合形态和生理指标，最适于番茄幼苗贮运的无机营养基质是基础基质（草炭︰珍珠岩=2:1）+缓释肥(20-9-11)30 g/盘，有机营养基质是基础基质+鸡粪10%+草木灰5%。
Abstract
In order to understand the change of morphological and physiological characteristics after storage, effects of six different nutritional substrates on tomato plug-seedlings quality maintenance under storage condition were studied in this paper. Tomato‘Qingyan No.1’was taken as experimental material, through simulated storage condition experiment and experimental analysis. The results showed that the contents of chlorophyll, soluble protein, and soluble sugar decreased in the leaves of tomato, but the falling ranges were different among the plug-seedlings cultivated with six different substrates and stored under same conditions. For tomato plug-seedlings storage, the optimal inorganic nutritional substrates was based substrates (turf: pearlite = 2:1) + SRFS (20-9-11) 30 g, organic nutritional substrates was basic substrates + 10% chicken manure+ 5% plant ash.
