Advantages of hydroponic vegetables

1. Good product quality, safety and hygiene.

Leafy vegetables are the stems and leaves of edible plants. Leafy vegetables such as lettuce and chicory are also mainly eaten raw, which requires the products to be fresh, clean and pollution-free. Shipei vegetables are easily polluted by parasites and bacteria, stained with soil and inconvenient to clean. Compared with soil cultured leafy vegetables, hydroponic leafy vegetables are of good quality, clean, fresh, good taste and high quality. It can be eaten directly.

2. It can be quantified in the plant factory.

Leafy vegetables are not easy to store, but they need annual production in order to meet the market demand. Soil cultivated leafy vegetables are cumbersome, requiring land preparation, border planting, fertilization, watering and other operations, while soilless cultivation is very simple. Only seedlings need to be implanted into the planting hole, and annual cultivation can be carried out on the same site. For example, lettuce can be sown, planted and harvested every day throughout the year, and continuously produced. Therefore, hydroponic cultivation is convenient for crop rotation arrangement and is suitable for planned and contract production.

3. It is not affected by the natural environment regardless of the light and peak seasons.

Leafy vegetables generally have short plants and do not need to add support facilities, so the facility investment is less than that of soilless cultivation of fruits and vegetables. Hydroponic vegetables have short growth cycle and fast turnover. Hydroponic culture belongs to facility production. It grows in the greenhouse and is generally not easy to be damaged by typhoon. Farmers who can supply fresh vegetables in typhoon season in coastal areas can often obtain higher profits.

4. Save fertilizer and do not need to change nutrient solution halfway.

The growth cycle of leafy vegetables is short. If there is no major physiological disease in the middle, it is generally only necessary to prepare the nutrient solution once from planting to harvest, and there is no need to replace the nutrient solution in the middle. Fruits and vegetables have a long growth period, even if there are no major physiological diseases. In order to ensure the balance of nutrients in the nutrient solution, it is necessary to renew the nutrient solution in half or in full.

5. High economic benefits. Hydroponic leafy vegetables can avoid continuous cropping obstacles, and the multiple cropping index is high. The operation rate of the facility is as high as more than 20 crops a year, and the production economic benefit is high.
