The purpose of fertilization is to meet the needs of vegetables, so that more output of vegetables. However, the types and quantities of nutrients absorbed by vegetables during different growth stages are also different. Therefore, different fertility stages have different fertilization priorities. Before and after the results are the key period for fertilization by vegetable farmers, but the results before and after the fertilization focus is not the same. Before the results, the focus of vegetable management in greenhouses was to promote roots and strong trees, which laid a good foundation for the continuous results of vegetables in the later period. The result period is for rapid expansion and increase production. According to the above characteristics, the vegetables should be flushed as follows before and after flowering results: Results before: can be washed Shigen Jia, mu dosage of about 10 pounds, root protection root; can also be used biochemical fertilizer flushing, such as Dayuan new fast gunners, etc., mu dose 40 to 80 kg. It is also possible to use 10 kg of balanced growth type aromatic fertilizer per acre to ensure balanced growth of roots and stems and leaves. In the result period, the amount of nutrients needed by vegetables increased, especially the demand for potassium. In order to promote fruit enlargement, high-potassium fertilizers were used for flushing to ensure the balance between vegetative growth and reproductive growth. Generally available Fang Fang 20-10-30 high-pot fertilizer 10 to 15 pounds can be applied. Result: Late stage: Result The late root function declines, and the ability to absorb nutrients declines. To coordinate vegetative growth and reproductive growth, fertilizers that promote root growth should also be added according to the characteristics of vegetables requiring fertilizers. For example, we can add roots and new fast gunners. The effect is good.
