| This paper is a report of the experiments to seek a best match type of matrix to improve the quality and output of the superior special vegetable by measuring and comparing the outcomes of different matrixes so that the method can be applied and promoted in production of Brassica oleracea L. × B.campeseris L. The findings of the research are as follows:1. In the experiments, six treatments are designed, namely: A (50%mushroom dregs + 50 % sand), B (50% sand + 50% perlite), C (50% vermiculite + 50% perlite), D (50% mushroom dregs + 25% sand + 25 % perlite) , E (50% sand + 25% mushroom dregs + 25% vermiculite) , F (100% crag cotton) . After in-depth investigation of each matrix in moisture content, volume density and proportion, and the seedling botanic nature (stem length, number of leaves, and the weight of single plant) of the Brassica oleracea L. × B.campeseris L. and measurement on activeness of the enzyme SOD, POD, and CAT, the outcomes of the experiments reveal that treatments A, D and E have better physical structure, with strong performance in moisture absorbing, and moisture retention, and fertilizer retention, and botanic features. Distinct differences are found in stem length, number of leaves, single plant weight compared with other treatments. Superior activeness of the leaves and roots are also observed, showing that the treatments can largely improve the growing of the plants.2. In the experiment, the quality index of the Brassica oleracea L. X B.campeseris L. (the content of Vitamin C, educing sugar, protein and the content and output of the soluble solid) are tested and measured. The results of the experiments indicate that with treatments A, D and E, the plants contain higher Vitamin C, educing sugar and protein, with better outlook, higher output and good economic benefits. Furthermore, the cost of the three treatments is considerably low, fully demonstrating the advantages of soilless cultivation.
