Application of hydroponic agriculture in smart glass greenhouse

Hydroponics is a kind of soilless cultivation mode. The hydroponics vegetable cultivation mode is very popular in leafy vegetable cultivation in recent years because of its shorter growth cycle, unrestricted planting area, and clean and sanitary. However, there are also some doubts and problems.

Are hydroponic vegetables safe

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. Hydroponic vegetables have a short growth cycle and are rich in vitamins and minerals necessary for the human body.

The reason why modern agriculture opposes the abuse of chemical fertilizers is not how harmful chemical fertilizers are to the human body, but that some chemical fertilizers damage the soil structure and the environment. Fertilizers and human sensations affect the taste of some crops at best-nutrient imbalance will lead to poor taste, but there is no harm to human health. (Guangyuan Greenhouse Yugong) In fact, the safety risk caused by pathogenic bacteria and parasites in human and animal manure is much higher than that of chemical fertilizer. Many developed countries have strict restrictions on the use of human and animal manure, but do not restrict the use of chemical fertilizer. Please note: The reason why agricultural experts oppose the abuse of chemical fertilizers is mainly because of soil structure and environmental pollution factors, not that chemical fertilizers are harmful to health!


Advantages of soilless cultivation

Labor-saving and high-efficiency, easy to light and simplify labor-saving production.

With strong controllability of environmental factors, it is easier to realize customized and factory production of agriculture. Achieve high-yield, high-quality and efficient production of agricultural products.


Problems and Suggestions of Soilless Culture in Practical Application

Does soilless culture seem to be a tall planting model that is only used in smart glass greenhouses? Wrong, hydroponics is just a planting mode. It can be planted in multi-span greenhouses, large-span spring and autumn sheds, sunlight greenhouses, and ground-inserting arch sheds. It’s just that we need the differences between these types of greenhouses when they are grown on the same ground, such as in terms of temperature.


The temperature of the root system in winter is lower than that of the soil, and the temperature of the root system in summer is higher than that of the soil. The temperature difference between day and night is also larger than that of the soil. Therefore, the overwintering stubble cultivation is generally more than half a month earlier than the ground planting in order to cultivate strong plants and developed root systems to improve drought resistance. Ability, for example, A-frame substrate cultivation strawberries must be planted before mid-September in Henan. (Guangyuan Greenhouse Yugong) The substrate temperature is low during the late period, the root system is weak, and the seedlings are not strong. Strawberry plants can easily enter the dormant period. NFT cultivation of tomatoes that use black-and-white film as a cultivation bag for overwintering is generally better externally, and light can be used to increase the temperature of the cultivation bag. In summer, it is better to be built-in underground to prevent high temperature from aging and death of the root system.
