Seedling raising substrate for vegetable strong seedlings

The invention discloses a seedling raising substrate for vegetable strong seedlings. The seedling raising substrate comprises the following components in parts by weight: 100-120 parts of a soil mixture, 20-25 parts of a bio-organic fertilizer, 5-8 parts of a chemical fertilizer, 3-6 parts of a bacteriostatic agent and 2-7 parts of humic acid, the bio-organic fertilizer and the chemical fertilizer are co-fermented and then added into the soil mixture. The soil mixture comprises vegetable garden soil, peat and fine sand, and the ratio of the vegetable garden soil to the peat to the fine sand is 9: (1-3): (1-2). Compared with single vegetable garden soil, the vegetable garden soil, the peat and the fine sand are adopted as main components of the matrix, nutrition loss can be better prevented by mixing the three components, and the bulkiness of the matrix is guaranteed. The bacteriostatic agent in the scheme can effectively inhibit normal growth of pathogenic fungus mycelia, can promote plant growth, and has the
