When winter arrives, when I went to the countryside to guide the production of greenhouse vegetables, I found that many farmers used fertilizers to work overtime, and the amount was too large, causing soil compaction, rotten roots, roots and plants to wilting, which seriously affected the economy of greenhouse vegetables. benefit. Based on years of practical experience, it is recommended that the fertilization of large vegetable sheds should be done in the following four points:
(1) The combination of organic fertilizer and inorganic fertilizer. That is, combination of slowness and quick effect. Many farmers apply fertilizers mainly to fertilizers, which are easy to reduce ground temperature. Fertilizers are mainly nitrogen fertilizers such as ammonium nitrate and urea. In the short term, vegetables grow well, but lack long-term effects, and plants are prone to premature aging. Some fertilizers use cake fertilizer ( Hemp seed cake, cotton cake, bean cake) and diammonium phosphate (or ammonium nitrate) are the main effects, the effect is poor, because the cake fertilizer fermentation takes a certain time.
(2) Combination of topdressing fertilization and flushing fertilization. The fertilizer is mainly composed of multi-component fertilizer, and the combination of topdressing and flushing is adopted to solve the problem of surface root fertilizer requirement. On the other hand, top dressing can activate the soil layer, increase the root elongation area and supplement the plant nutrition.
(3) The combination of large water and small water. Many farmers, regardless of seedling stage and fruiting stage, apply fertilization with large water, which makes the fertilizer water too large, causing seedling disease, rotten roots and roots. Regardless of biological fertilizer, organic fertilizer, and chemical fertilizer, it is necessary to look at the fertilizer used for seedlings, scientifically and reasonably, and timely cultivating loose soil after the fertilizer and water have passed.
(4) Combination of biological fertilizer and chemical fertilizer. Bio-fertilizers contain a variety of beneficial bacteria, which activate soil, increase ground temperature, and regulate soil nutrients. Combined with inorganic fertilizer (fertilizer), it can remove fertilizer damage, increase soil organic matter, enhance the nutrient function of nutrients, and promote root development.
