The new mode of tidal cultivation and agricultural planting is applied in greenhouses.

    Tide cultivation is a kind of soilless cultivation planting mode. The tidal cultivation mode of vegetable cultivation has been very popular in leafy vegetable cultivation in recent years due to its shorter growth cycle, unlimited planting areas, and cleanliness.

    The seedlings are raised by watering nutrient solution or using tidal cultivation without any substrate. Its advantages can effectively control the optimal requirements of flowers for temperature, water, light, nutrients and air in the process of growth and development. Since soilless cultivation of flowers does not require soil, it can expand the planting range, accelerate the growth of flowers, improve the quality of flowers, save fertilizer and water, save manual operations, and save labor and costs.

     An introduction to tidal cultivation

    Tidal cultivation is a type of soilless cultivation. Tide cultivation refers to the direct contact of plant roots with nutrient solution, according to the way of high tide and low tide. In this method, the cultivated plants directly absorb nutrients from the solution, the corresponding root system has developed fibrous roots, and the main root is obviously degraded compared to open field cultivation.

Labor saving, labor saving and easy management Tidal cultivation does not require cultivating, ploughing, weeding and other operations. Watering and topdressing are solved at the same time, and the liquid supply system is regularly and quantitatively supplied, and management is very convenient.

    Is tidal cultivation of vegetables safe?

    Tidal vegetables and vegetables refer to the vegetables that most of the roots grow in the layers of nutrient solution and only provide water, nutrients and oxygen through the nutrient solution, which is different from the vegetables cultivated under the traditional soil cultivation form. Tidal vegetables have a short growth cycle and are rich in a variety of vitamins and minerals necessary for the human body.

The reason why modern agriculture opposes the abuse of chemical fertilizers is not because of how harmful chemical fertilizers are to the human body, but because some chemical fertilizers cause damage to the soil structure and the environment. Fertilizers and human perception can affect the taste of some crops at most—unbalanced nutrients can lead to poor taste, but they are not harmful to human health. In fact, the safety risk caused by pathogenic bacteria and parasites in human and animal feces is much higher than that of chemical fertilizers. Many developed countries have strict restrictions on the use of human and animal feces, but do not restrict the use of chemical fertilizers.

    2. Conducive to the realization of agricultural modernization Tidal cultivation makes agricultural production get rid of the constraints of the natural environment and can be produced according to human will.    This method of production, to a large extent, cultivates according to the quantitative indicators, which is conducive to the realization of mechanization and automation, thereby gradually moving towards industrialization.

    The root temperature in winter is lower than the soil temperature, the root temperature in summer is higher than the soil temperature, and the temperature difference between day and night is larger than that of the soil. Therefore, the cultivation of overwintering stubble is generally more than half a month earlier than that of ground planting, so as to cultivate robust plants and developed root systems and improve drought resistance. ability.
