Embodiment Construction

[0018] The present invention will be further described in detail through the embodiments below in conjunction with the accompanying drawings. It should be understood that the following embodiments are only illustrative, and the present invention is not limited thereto.

[0019] The sweet potato atomization cultivation equipment of present embodiment is as figure 1 Said, the top of the cultivation tank 1 is set up with a nylon grid 2, covered with a planting plate 3 with planting holes on the nylon grid 2, the thickness of the planting plate 3 is 5.5cm, the row spacing of the planting holes is 40cm, the hole spacing is 20cm, and the aperture is 2.5cm; 1 Lay 0.08mm anti-aging non-drip film inside. After the sweet potato plant 4 is planted, the root system grows downward through the grid. The nutrient solution pool 7 holds the nutrient solution, and the nutrient solution is pumped into the liquid supply pipe 5 by the liquid supply pump 8 . The liquid supply pipe 5 is a UPVC pip...

Abstract

The invention discloses a sweet potato aeroponics cultivation method. The method comprises the following steps: erecting a net rack on the upper part of a cultivation groove, and mounting a spray head which is controlled by an automatic periodical spraying device on the lower part of the cultivation groove; covering the net rack with a plant fixing plate which is provided with plant fixing holes; inserting sweet potato plants into the plant fixing holes and fixing the plants; employing the net rack to support upper parts of root systems of the plants, and remaining lower parts of the root systems hung in the air in the cultivation groove; spraying an atomized nutrient solution over the root systems by the spray head periodically to provide nutrient substances and water for growth of the sweet potato. In the aeroponics cultivation method, growth factors such as temperature, light, water, air, fertilizer and the like can be controlled manually to an optimum state to ensure moist state of the root systems and acquire adequate oxygen, which causes full growth of vegetative mass of the sweet potato, high yield of the sweet potato, continuous production and greatly improved yield.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, in particular to a method for soilless cultivation of sweet potatoes. Background technique [0002] Soilless cultivation technology is currently one of the most effective means to solve the difficulties of soil pollution, salinization, and continuous cropping obstacles in facility production. Fast, it will deteriorate the oxygen supply of the root system and affect the growth of the plant. Therefore, the key to developing soilless cultivation technology is how to solve the contradiction between oxygen supply and liquid supply. Vapor mist cultivation is a soilless cultivation technique that uses a spray device to atomize the nutrient solution to the root system of the plant to provide the water and nutrients needed for plant growth. It is the solution to the root water-air contradiction in all soilless cultivation techniques best form. [0003] Plant aeroponics (aeroponics, aeroponics)...
