First, leaf vegetables. Leafy vegetables refer to green leafy vegetables with short growing period, such as cabbage, green vegetables, leeks, spinach,
Celery, lard, and so on, its leaves whole plant for consumption. Due to the dense planting of this vegetable plant group, the distribution of roots is shallow, and the requirements for soil available nutrients are urgent and sensitive. Once the nutrient is insufficient, the leaves grow slowly and become yellow, so the fertilization method is dominated by topdressing. The nutrient elements should be dominated by quick-acting nitrogen fertilizers. Generally, after the seedling stage and every harvest of a product, the fertilizer is immediately top-dressed to promote the rapid growth of the leaves of the plant. The amount of topdressing fertilizer per acre is 8–10 kg of urea or 400–500 kg of human waste, or watered on a per plant basis to facilitate absorption and utilization as soon as possible.
Second, root vegetables. Root vegetables refer to root vegetables such as artichokes, radishes, and cabbage, which are formed after a long growing period and the formation of vegetative organs (leaves and stems). The roots, tubers or leaves of the whole plant are edible. Since this kind of vegetables enters a period of vigorous growth after product formation, the growth of the leaves will gradually stop. Therefore, the fertilization method should be weighed with the base fertilizer and the early top-dressing, and be mixed with a small amount of available nitrogen and potassium fertilizers, and the fertilizer should be quickly applied early at the seedling stage or after planting. . Mushi urea 4-6 kilograms, or 300-400 kilograms of human waste, to promote early-onset and long, put up high-yield shelves. In the initial stage of product formation, 6-8 kg of phosphorus and potassium fertilizers were applied per acre to promote rapid transfer of nutrients from the stems to the reproductive organs and achieve high yields. So when the 1-2% aqueous urea solution is sprayed 1-2 times (5-7 days interval), the functional period of the leaf can be prolonged without premature aging.
Third, fruit vegetables. Fruit vegetables refer to vegetables that have a longer growing period, such as solanaceous fruits, legumes, and melons. Because the vegetative growth and reproductive growth of this kind of vegetables take place simultaneously, the time is longer and more three elements are needed. Therefore, the fertilization method should be weighed with the base fertilizer and top-dressing. The nutrient elements should be dominated by nitrogen, phosphorus and potassium. The principle of flowering and weighting early, and top dressing, and after each harvest of a fruit, immediately applied a quick-improving nitrogen fertilizer, prompting the rapid formation and enlargement of the fruit.
