Features and advantages of hydroponic vegetables

In recent years, the demand for healthy, clean, nutritious, and freshly supplied vegetables has been increasing all over the world. Because there are plant growth lights and other indoor planting equipment, soilless culture, as a production method that is not restricted by geographical and climatic conditions, is clean, efficient, and safe, and almost meets all the needs of consumers, and it is becoming more and more planted. Favorite. At present, there are three main types of soilless culture: hydroponic culture, rock wool culture and substrate culture.

What is hydroponics?

Hydroponic vegetable refers to the vegetable that most of the root system grows in the nutrient solution layer and only provides water, nutrient and oxygen through the nutrient solution, which is different from the vegetables cultivated under the traditional soil cultivation method. The characteristic of hydroponic vegetables is that the root system is mainly milky white capillary roots to absorb water and nutrients; the root system adapts to the aquatic environment, and there are some aerial roots on the periphery to absorb oxygen; the growth cycle is short and the market is early.
Vegetable varieties suitable for hydroponic culture: lettuce, celery, spinach, arugula, leaf beet and other leafy vegetables. In addition, some fruits and vegetables can also be hydroponics, such as tomatoes, cucumbers, melons and so on.

Advantages of hydroponics

Hydroponic vegetables have a crisp and sweet taste, fast growth speed, short cycle, maximum use of fertilizers, greener, safer, healthier and cleaner. Compared with traditional planting techniques, hydroponics has the following advantages:
1. The product quality is better, cleaner, safer, crispy and sweet, and easier to process and eat. Leafy vegetables mostly eat the stems and leaves of plants, such as lettuce and arugula, which are basically raw food, which requires the products to be fresh, clean, and pollution-free. Soil-cultured vegetables are easily stained with soil and are inconvenient to clean. Hydroponics avoids these inconveniences, is cleaner and safer, and also greatly saves processing costs in processing plants.
2. It can be planted annually on the same site, with fast growth speed and short cycle, which can solve the problem of off-season vegetable supply and better meet market demand. Leafy vegetables are not easy to store, but in order to meet market demand, annual production is required. Soil cultivation of leafy vegetables requires cumbersome operations such as soil preparation, planting, fertilization, and watering. However, soilless cultivation is very simple, just plant the seedlings in the planting holes. For example, lettuce can be sown and planted at any time. Harvesting, continuous production without interruption. Therefore, hydroponics facilitates cropping arrangements and is suitable for planned and contracted production.
3. Basically not affected by insect pests and natural disasters, the nutrient solution can be recycled, saving management costs, and high economic benefits. Leafy vegetables have a short growth cycle. If there are no major physiological diseases in the middle, generally only one nutrient solution needs to be prepared from the planting to the harvest, and there is no need to change the nutrient solution in the middle. In addition, hydroponic leafy vegetables can avoid continuous cropping obstacles, and the multiple cropping index is high. The facility operation rate is as high as 10 times a year, which greatly saves management costs and achieves higher economic benefits.
