Summer cabbage should promote growth and accelerate growth throughout the growing season. Watering in the seedling stage masters the three waters and the seedlings, and the five waters are fixed. Three times of water is poured during the emergence period, four times and five times of water are the water for the seedlings and the water for the seedlings, and the cultivating is timely after the watering or after the rain. Combined with the seedling water, apply the fertilizer once, use urea or ammonium sulfate, apply the hole or ditch. The fertilization point is 8~10 cm away from the seedlings, and the roots and leaves are less injured. The water was poured once in the first 10 days of the bag, and the seedlings were planted after the cultivating. When the leaf color turns green, the leaves become thicker, and the seedlings end when there is a slight wilting at noon. Spraying vegetables and stalks before the core to promote the growth and development of the plant, improve leaf hypertrophy. When pouring water into the seedlings, combined with watering, urea is applied along the water, and it is often observed later. When the surface is white, water is poured in time until the water is stopped 5 to 7 days before harvesting. Be careful not to damage the leaves when harvesting, affecting sales.
