Greenhouse soilless cultivation supplies corresponding nutrients according to different growth stages of crops, which not only ensures that crops can be "satisfied", but also ensures that there is no waste. However, in our greenhouse production, vegetable farmers do not carry out soil testing and formula fertilization, resulting in excessive accumulation of certain elements in the soil, while insufficient absorption of certain elements. For example, in recent years, vegetable planting areas have used a large amount of potassium fertilizers during the vegetable fruiting period while the application of ammonia fertilizers has been relatively reduced, resulting in excessive potassium in the soil, which has brought about a series of problems, such as inhibiting the absorption of calcium and magnesium in the soil. For a long time, many Vegetable farmers only pay attention to the supply of large amounts of nitrogen, phosphorus, and potassium to the soil, which will inevitably cause soil nutrient imbalance, especially in vegetable fields that have been cropped continuously for many years. The problem of soil nutrient imbalance is even more serious. In addition, different types of vegetables and different growth periods have different requirements for nutrients. If vegetable farmers do not fertilize according to the fertilizer requirements of vegetables, when certain elements are deficient or excessive, the physiological functions of vegetables will be hindered. This is One of the common causes of physiological problems such as deficiency syndrome, premature aging, and yellow leaves.

The advantages of soilless cultivation in greenhouses: most of the vegetables grown in soilless cultivation are leafy vegetables, and they are carried out in hydroponics. This is because the growth cycle of leafy vegetables is short, and there is no need to replace the nutrient solution midway, saving fertilizer. Moreover, the multiple cropping index is high, and the operation rate of the facility is as high as more than 20 crops a year, and the production economic benefits are high. Three-dimensional cultivation can make full use of space, while leafy vegetables are short, grow rapidly, and have a short cycle, making them most suitable for large-scale three-dimensional cultivation. This new cultivation model will become the mainstream of agriculture in the future.
