From 1979 to 1980, we carried out the plantation seedling experiment of Chinese cabbage in the suburbs of Taiyuan. From the two years’ situation, we can see that the quality of seedlings meets the criteria of strong seedlings. After planting, the root system develops well, grows fast and the yield of early spring and yield per mu increases. First, the material and methods (A) nursery plant: from the sowing seedlings, seedling greening room, planting Qianmiao room composition. Seeding seedling room selection general studio, room temperature to maintain 26-28 ℃, relative humidity to maintain 75-80%. Seedling green room with angle (30 × 30 × 3 milliliters
