Embodiment 1

[0085]Cultivate the lettuce with the above-mentioned Hoaglund nutrient solution, plant five groups of lettuce, and the roots of the first group to the fifth group are immersed in the nutrient solution at a depth of 0.3cm, 0.5cm, 0.7cm, 1.0cm, respectively. cm, 1.5cm; and the height of the liquid level in the high tide stage is 1.5cm, 2cm, 3cm, 4cm, 5cm respectively. The high tide time of each cycle is 20 minutes, and the low tide time is 40 minutes. The nutrient solution circulates. The liquid flow velocity is controlled within the range of 0.02-0.4 m / s during high tide and low tide, and the flow rate is controlled at 0.08-1.2 liters / second. within range. After a period of cultivation, the growth state of the lettuce was evaluated.

Embodiment 2

[0090] The lettuce was cultivated with the nutrient solution of the self-made formula described above, and five groups of kale were planted. The roots of the first group to the fifth group were immersed in the nutrient solution at a depth of 0.3cm, 0.5cm, and 0.7cm respectively. cm, 1.0cm, 1.5cm; and the height of the liquid level in the high tide stage is 1.5cm, 2cm, 3cm, 4cm, 5cm respectively. The high tide time of each cycle is 30 minutes, and the low tide time is 60 minutes. During the high tide and low tide, the liquid flow velocity is controlled within the range of 0.02-0.4 m / s, and the flow rate is controlled within the range of 0.08-1.2 liters / s. After cultivating for a period of time, the growth state of Chinese kale was evaluated.

Embodiment 3

[0095] The lilies were cultivated with the nutrient solution of the self-made formula described above, and five groups of lilies were planted. The roots of the first to fifth groups were immersed in the nutrient solution at a depth of 0.3cm, 0.5cm, and 0.7cm respectively during the tide-down stage. . The high tide time of each cycle is 40 minutes, and the low tide time is 90 minutes. During the high tide and low tide, the liquid flow velocity is controlled within the range of 0.02-0.4 m / s, and the flow rate is controlled within the range of 0.08-1.2 liters / s. After a period of cultivation, the growth state of the lilies was evaluated.

Abstract

The invention provides an ultra-shallow liquid layer tide planting method, which comprises the steps of maintaining the liquid level of a liquid stream at 0.3-1.5 cm in the case of falling tide, and maintaining the liquid level of the liquid stream at 1.5-5.0 cm in the case of rising tide. A part of root system is soaked into liquid in the case of falling tide to sufficiently absorb oxygen gas; while in the case of rising tide by liquid feed, the root system is mostly or fully soaked into the liquid to sufficiently absorb nutritional ingredients. Compared to the conventional shallow liquid stream technique and deep liquid stream technique, the ultra-shallow liquid layer tide planting method disclosed by the invention is more beneficial to plant absorption of oxygen gas and nutritional ingredients, effectively reduces the system energy consumption, is more beneficial for plant biomass increase, and greatly avoids the opposite trend phenomenon during plant growth.

Description

technical field [0001] The invention relates to a plant planting method, in particular to a super shallow liquid layer tidal planting method. Background technique [0002] Soilless cultivation is the most advanced cultivation technology in the world today. Because soilless cultivation has many advantages over soil cultivation, the development of soilless cultivation area has shown a linear upward trend in recent years. In soilless culture, artificially prepared nutrient solution is used to supply the needs of plant mineral nutrition. Soilless cultivation is a cultivation technique that uses nutrient solutions containing essential elements for plant growth and development to provide nutrients without using natural soil, so that plants can normally complete the entire life cycle. [0003] Soilless cultivation can make the plants grow rapidly and robustly, with many and early flowering, big and fragrant, cold and heat resistant, and less pests and diseases. For many crops, su...
