Vegetables are essential foods in people's daily lives, playing an important role in ensuring people's nutritional health and improving their quality of life. However, due to the scarcity of land resources, severe environmental pollution, and frequent occurrence of diseases and pests, traditional soil cultivation methods are no longer able to meet people's needs for the quantity and quality of vegetables. Therefore, hydroponic cultivation technology, as a new type of vegetable cultivation method, has received more and more attention and promotion.
Although China is a major agricultural country, it has developed relatively late in the field of organic agriculture, currently accounting for less than 5% of domestic organic agriculture. The development of hydroponic vegetable cultivation industry in China is relatively late and currently in its initial stage, with only good development in developed cities such as Beijing, Shanghai, Tianjin, Guangdong, and Shenzhen. But with the rapid development of China's economy, the demand for healthy food among residents has increased. Driven by the demand for green consumption, the demand for hydroponic vegetables in the market has increased.
Ebb and flow table is a technique of irrigating from the bottom of a cultivation container. When the nutrient solution is in high tide, plants use capillary action to absorb water and nutrients. The nutrient solution is recycled, filtered, and disinfected after low tide, and can be recycled to achieve the goal of water-saving and fertilizer saving.
Advantages of Ebb and flow table in vegetable industrialization:
1. Under relatively controllable environmental conditions, the nutrient supply for crop growth and various environmental factors can be regulated with relative precision. Therefore, the yield and quality of hydroponic vegetables are incomparable to traditional soil cultivation. Whether in terms of safety, vegetable taste, and internal quality, they are far superior to soil cultivation.
2. The fast growth rate of hydroponic vegetables and fruits is due to the sufficient and timely supply of nutrients, and the controllable growth conditions in greenhouse and other environments. The various external environmental conditions for the growth of vegetables and fruits meet or are close to their optimal growth requirements. Therefore, the growth rate of hydroponic vegetables and fruits is faster than that of soil cultivation.
3. Ebb and flow table is an efficient and water-saving planting equipment suitable for potted plant planting, especially for factory planting of plants. In plant hydroponic plants, automatic irrigation mode can be set through the touch screen, greatly reducing labor costs and achieving a relatively high level of automation.
4. Free from regional restrictions and make full use of space. Hydroponic cultivation frees crops from the soil environment, and can be utilized in deserts, wastelands, or difficult to cultivate areas on Earth.
Hydroponic cultivation technology has freed agricultural production from the constraints of the natural environment and is a controlled agricultural production method. Cultivating according to quantitative indicators to a large extent is conducive to achieving agricultural mechanization and automation. Nowadays, hydroponic vegetables are increasingly popular among consumers, and using professional hydroponic equipment for large-scale hydroponic vegetable cultivation can achieve vegetable industrialization.
