摘　　要：比较以玉米秸秆为原料制作的压缩栽培基质对番茄及辣椒幼苗的生长状况及营养元素积累的影响,以确定压缩基质块的基本组成,为玉米秸秆作为育苗基质提供依据。测定压缩基质的基本性质,观测番茄及辣椒幼苗的生长指标和生理指标以及营养元素积累情况,分析压缩基质块的组成对幼苗生长情况和营养元素积累的影响。含有腐熟玉米秸秆的压缩基质番茄和辣椒幼苗生长状况及营养元素积累优于含未经发酵玉米秸秆的基质;两种作物幼苗在栽培基质上各项指标具有相似的变化规律。其中在处理3(T3腐熟玉米秸秆∶蛭石=2∶1)压缩栽培基质上番茄和辣椒幼苗的出苗率、壮苗指数、根系活力、叶绿素含量最高,营养元素积累表现最佳,各项指标均比对照基质好。玉米秸秆压缩基质块可以作为栽培基质使用。The objective of this study was to compare the effects of corn stalk compressed matrixes on growth and nutrient elements accumulation of tomato and chili seedling. For determination of the composition of compressed matrix, to provide the basis for the utilization of corn stalk to seedling substrate. By measuring the fundamental properties of compressed matrix and observing the growth indexes and physiological indexes and nutrient elements accumulating of tomato and chili seedling grown on the matrix, the effect of matrix composition on seedling growth and nutrient elements accumulation were analyzed. Results showed that compressed matrix with fermented corn stalk were more suitable for seedling growth and nutrient elements accumulating than raw corn stalk. All indexes of two variety seedling grown on the prepared matrixes got the similar changing rule. Matrix T3(fermented corn stalk∶vermiculite = 2∶1) got the best germination percentage, seedling index, root vitality, chlorophyll content and nutrient elements accumulating, which were better than control matrix. In conclusion, the compressed corn stalk matrix could be utilized for seedling cultivation.
