It seems like a very simple matter to fertilize vegetables. Years of production experience summed up some experiences. Fertilization should follow the principle of “giving full use of basic fertilizers and reasonably top-dressing fertilizersâ€. Water management should adhere to the principle of “appropriate amount of timely, rather rather less, moreâ€, and here mainly talk about how to apply fertilizer. Basal fertilizer must be cooked. Basal fertilizers are generally farmyard manure such as manure and compost. Before the vegetables are sown or planted in the soil, these farmyard fertilizers not only contain many elements needed for vegetables, but also can supply a large amount of organic matter in the soil and improve the soil very well. The manure used as a base fertilizer must be fully decomposed. If it is fresh manure or compost without sufficient maturity, it must be applied earlier to ensure that it is naturally matured in the soil before sowing or planting of the vegetables. Otherwise, it will bring a lot of germs and it will be harmful. Basal fertilizers have both full and partial application methods. Root vegetables, spinach, leeks, and other closely planted leafy vegetables, as well as a large amount of application, can spread manure, compost, etc. evenly onto the ground and plough them into the soil. For pumpkins, eggplants, cabbages, etc., where there is a small amount of crops or manure, etc. with relatively small amounts, it is possible to conduct trenching between rows or digging holes between plants. Top dressing should be flexible. Top dressings are mainly quick-acting fertilizers such as human waste, ammonium sulfate, compound fertilizer, and urea. Only when the vegetables have 3 to 4 true leaves or planted seedlings survive the application. The number and amount of topdressing should depend on the type of vegetables, growing season, climate, soil moisture, and fertility. When the plants are small, the fertilizer concentration should be thin, and the amount of one application can be less, and the number of fertilizers can be gradually increased as the plants grow. Fertile soil, strong vegetable growth, can be applied less, on the contrary, you should give more. Usually topdressing every 15 to 20 days. Fast-growing vegetables, such as spinach and pakchoi, should be applied thinly and fertilized every 7 to 10 days. In short, topdressing should adopt the method of “first lighter, thicker, and less food†and timely top-dressing multiple fertilizers in stages to meet the nutritional needs of vegetables in different growth periods. Different types of vegetables require different fertilizers. Cabbage and other leafy vegetables must be supplied with sufficient nitrogen to grow quickly. Beans, potatoes, etc. should be given more potassium fertilizer in order to increase production and quality. Tomatoes, eggplants, melons, etc., in addition to the application of nitrogen fertilizer, should be more phosphorus and potassium fertilizers, in order to promote fruit growth, early maturity and improve quality.
