Leafy vegetable fertilization techniques

Leafy vegetables refer to fast-growing vegetables, such as cabbage, green vegetables, leeks, spinach and celery, which are mainly made of fresh leaves, petioles or tender stems. The vegetable has high planting density and shallow root distribution. It is urgent and sensitive to soil available nutrient requirements. Once the nutrient supply is insufficient, the leaf growth slowly turns yellow. The fertilization method should be based on topdressing, and the nutrient elements should be based on quick-acting nitrogen fertilizer. Generally, after the seedling stage and after harvesting one product, the fertilizer will be topdressed once, which will promote the rapid growth of the leaves of the lower jaw plant, and apply 8-10 kg of urea per mu or 500 kg of decomposed manure and urine, strip or planted by plant, in order to facilitate the plant to absorb and use as soon as possible.
