Cabbage has strong water-absorption and root-absorbing ability, and it is good for fertilizer and fertilizer. It needs more nitrogen, especially the late-maturing species needs more than the early-maturing species. The proportion of N, P and K absorbed throughout the whole growth period is N: P2O5: K2O = 3:1:4. 1. Base fertilizer combined with Mushi's decomposed organic fertilizer 4000-5000 kg, superphosphate 25-30 kg, and potassium sulfate 10-20 kg. When planting, combined with 400-500 kg of decomposed organic fertilizer or 500 kg of cake fertilizer, the fertilizer will be applied to the planting hole, so that fertilizer and soil blending evenly. 2, top dressing cabbage cabbage dressing should be early, 4 to 5 days after planting combined with watering seedlings, acres with water rushed 7-10 kg of ammonium sulfate to speed up the survival of seedlings. When the lotus is in the late stage, when it starts to wrap, it is combined with water to topdress 1-2 times, and each time, 15-20 kg of ammonium sulphate or 800 pounds of decomposed manure is flushed with water. In late-maturing varieties, more fertilizer was applied in the middle of the ball, and 10 kg of ammonium sulfate was used. The application method was the same as that of the previous two top dressings, which promoted uninterrupted and vigorous growth of cabbage, which had a significant effect on increasing yield and improving quality.
