The ebb and flow seedbed is composed of seedbed tray, rolling shaft, bracket, seedbed frame, hand wheel, horizontal support and inclined rod. The standard height of the seedbed is generally 0.7 or 0.75m, which can be fine-tuned up and down; the standard width is 1.7m, and the length can also be determined according to the width of the greenhouse. The length can be customized according to user requirements, generally 20-30m, but the length of the seedbed should not exceed 40m, so as not to affect the shaking effect. The size of the seedbed tray is generally 1.7*4.5 (4 or 5) meters, and other specifications can also be designed according to needs. The seedbed tray is made of ABS material, which has high anti-corrosion performance, good load-bearing capacity and long service life.

The advantages of Ebb and flow table irrigation are high irrigation uniformity, low labor intensity, large greenhouse space utilization, crop leaves are not easily damped, leaf diseases rarely occur, and irrigation water can be fully recycled to reduce water waste.

Ebb and flow irrigation seedbed: ebb and flow phenomenon is a natural phenomenon in coastal areas. It refers to the periodic movement of seawater under the action of tidal forces of celestial bodies (mainly the moon and the sun). It is customary to call the vertical fluctuation of the sea surface as tide.
