First, leafy vegetables. Leafy vegetables refer to green leafy vegetables with shorter growth periods, such as cabbage, green vegetables, leeks, spinach,
Celery, kale, etc., for the whole plant for edible. Due to the high density of plant tissues and the shallow distribution of roots, the requirements for soil available nutrients are urgent and sensitive. Once the nutrient is insufficient, the leaves grow slowly and yellow, so the fertilization method is mainly based on topdressing. 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 plant. The amount of topdressing per mu is 8-10 kg of urea or 400-500 kg of human excrement or watering by plant, so as to facilitate absorption and utilization as soon as possible.
Second, root vegetables. Rhizome vegetables refer to root vegetables that are formed after the growth period is long and the vegetative organs (leaf stems) are formed, such as artichokes, radishes, cabbage, etc., and are eaten by whole roots, tubers or leaf balls. Since the growth of the vegetables enters the product, the growth of the leaves will gradually stop. Therefore, the fertilization method should be based on the base fertilizer and early topdressing, and a small amount of available nitrogen and potassium fertilizers should be added, and the fertilizer should be applied quickly at the seedling stage or after planting. . Apply 4-6 kg of urea per mu, or 300-400 kg of human excrement, promote early and long-term growth, and set up a shelf for high yield. In the early stage of product formation, 6-8 kg of phosphorus and potassium fertilizer is applied per acre to promote the rapid transfer of nutrients in the stems to the reproductive organs to achieve high yield. When the 1-2% urea water solution is sprayed 1-2 times (interval 5-7 days/time), the leaf function period can be prolonged without premature aging.
Third, fruit vegetables. Fruit vegetables refer to vegetables that have a long flowering period in the growing season, such as solanaceous fruits, legumes, melons, and the like. Because the vegetative growth and reproductive growth of this kind of vegetables are carried out simultaneously, the time is long, and there are more three elements required. Therefore, the fertilization method should be based on the base fertilizer and the whole process. The nutrient elements should be mainly nitrogen, phosphorus and potassium, according to the base fertilizer. The principle of weighting early in the early stage and the weight of the fruit during the fruiting period, and after each harvest of the fruit, immediately applied a quick-acting nitrogen fertilizer to promote the rapid formation and expansion of the fruit.
