Vegetables are an essential source of nutrition for everyone on the table. Its short growth cycle, multiple types, and rich nutrition make it an important part of people's food culture. The use of protected land to produce vegetables (such as greenhouse vegetable production, etc.) makes its production more free and less affected by the natural climate. However, vegetables in protected areas need to be hypertrophic, and the product quality and hygiene requirements are strict. Therefore, for the fertilization of vegetables in protected areas, the experts of Gemba Ecological Planting will introduce the following three principles. The majority of farmers can learn from them:
1. Reasonable fertilization according to the type of vegetablesThere are many kinds of vegetables, and the products include different parts such as roots, stems, leaves, flowers and fruits. Different vegetables have different needs for various nutrients. Fruit vegetables, in addition to the necessary nitrogen fertilizer should also be appropriate addition of phosphorus and potassium fertilizers, but also pay attention to the application of high-quality organic fertilizer. Leaf vegetables need to use nitrogen fertilizer in order to promote the growth of leaf organs, so the absorption of nitrogen fertilizer in large quantities, which also requires farmers to stage additional nitrogen fertilizer. Because legumes can fix nitrogen in the air by nitrogen-fixing bacteria, nitrogen fertilizer can be used less frequently in addition to seedlings in the cultivation process. Fruit and vegetable vegetables, because in the later stages of vegetative growth, involve reproductive growth such as flowering, fruiting, and so on. Therefore, in the early stage of the supply of nitrogen fertilizers, fertilizers of “small amount but all varieties†nutrition are to be applied at this time.
2. Balanced fertilization and emphasis on the use of organic and bacterial fertilizersAt present, there is a widespread phenomenon in rural areas that focuses on nitrogen and phosphate fertilizers, ignoring potash fertilizer, and ignoring organic fertilizer and trace fertilizer. This makes it impossible for vegetables to absorb nutrients in a balanced manner, which makes it prone to thorny problems. Therefore, achieving a balanced supply of nutrients is also one of the keys to planting vegetables in protected areas. In addition, there is a large variety of organic fertilizers and bacterial fertilizers in the production of protected vegetables, and the effects of some new fertilizers (such as microbial fertilizers) are not clear, so organic fertilizers and fungus fertilizers cannot be used rationally. Based on this, Beijing Huaxia Kangyuan Science and Technology Co., Ltd. experts on the use of fertilizer experts for farmers to use organic fertilizer and biological fertilizer can not start with the following recommendations: Conservation of vegetable cultivation and application of basal fertilizer often use organic fertilizer and mixing 1-2 per acre Kilo gold baby microbial fertilizer (click here) and apply. After the microbial fertilizer is applied to the soil, it can rapidly form a powerful and powerful probiotic group, not only to repair the structure around the soil, but also to activate phosphorus and potash which are difficult to use in the soil, thereby making the land richer in nutrients. In the cultivation of vegetables in protected areas, it is required that the base fertilizer includes all phosphorus fertilizers for vegetable growth, 2/3 of potassium fertilizer, and 1/2 of nitrogen fertilizer. Jinbao microbial fungus is a high-tech product developed from the principles of plant nutrition physiology and rhizosphere soil microecology. The addition of fungicide makes the absorption of some nutrients much easier. The remaining nutrients needed for vegetable growth can be easily achieved by adding inorganic fertilizers during the management process.
3. Fertilization according to the cultivation environment Although the requirements for the natural environment of cultivated vegetables are reduced, the management of protected vegetables in different seasons and regions is still very different. This also requires farmers to apply scientific fertilization according to the specific cultivation environment. The temperature is suitable, the crop grows vigorously, and the amount of fertilizer required is also large. The greenhouse vegetable has high temperature in October-November and March-April, which is conducive to the decomposition of the fertilizer. At this time, the vegetable grows more vigorously, and more fertilizer can be used. In other low-temperature months, no fertilizers are applied or reduced in greenhouses. If urea is difficult to decompose after use below 12°C, the crop is not easily absorbed. Details can be consulted: Beijing Huaxia Kangyuan Technology Co., Ltd.
