Watering vegetables and watering these seemingly simple things is not simple in the view of Li Zhi, vegetable expert of the Provincial Academy of Agricultural Sciences. Recently, in an interview with reporters, he introduced the use of vegetable fertilization techniques. Basal fertilizers are generally dominated by delayed organic fertilizers such as manure and compost. Before the planting or planting of vegetables, it is applied to the soil to supply the growing vegetables. These farmhouse fertilizers not only contain many elements needed for vegetables, but also supply a large amount of organic matter in the soil, which can very well improve the soil. “Farming manure used as basal fertilizer must be fully decomposed. If fresh manure or compost without sufficient maturity is applied, it must be applied earlier to ensure that it is naturally matured in the soil before sowing or planting the vegetables. Otherwise, it will bring about A lot of germs are harmful," Li Zhi reminded. Base fertilizer application methods are comprehensive and partial. Planting root vegetables, spinach, leeks, and other closely planted leafy vegetables, as well as a large amount of application, can spread manure and compost evenly on the ground, and then it is convenient for ploughing into the soil. Pumpkin, eggplant, cabbage, broccoli and other crops with wide plant spacing, or manure, etc., can be used for digging trenches 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 had 3 to 4 true leaves or planted seedlings survived, topdressing began. The number and amount of topdressing should depend on the type of vegetables, growing season, climate, soil moisture, and fertility. The smaller the vegetable plant, the thinner the fertilizer should be, and the smaller the amount of fertilizer applied, the more the number of fertilizers will increase as the plant grows. Fertile soil, strong vegetable growth, can be applied less, on the contrary, you should give more. Usually top-dressing every 15-20 days. Fast-growing vegetables, such as spinach and pakchoi, should be applied thinly and applied every 7-10 days. In short, topdressing should adopt the method of “first lighter, thicker†and “eat more meals less†and timely and appropriate fertilizers in multiple stages, so as to ensure that the fertility does not come off in order to meet the nutritional needs of growing vegetables, and to do Avoid excessive concentration and affect growth. Different types of vegetables require different fertilizers. Mustard, cabbage and other leafy vegetables, to provide sufficient nitrogen fertilizer in order to quickly grow. Beans, potatoes, etc. should be given more potassium, can 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.
