How to use the seedbed conveniently and the greenhouse space more effectively has become the further demand of greenhouse users. Indoor mobile seedbed produces 1 mobile seedbed under use requirements, The nursery bed is usually made of light steel, Fixed to the ground, The height is determined to be suitable for people to bend over and operate. It is generally 0.7 m, The width depends on the fact that people can easily operate the crops on the seedbed by bending over and extending their arms, generally taking 1.5-2.0 m; The length depends on the length and use requirements of the greenhouse. The design and application of the mobile seedbed are to improve the utilization rate of the greenhouse by sharing a road with multiple seedbeds.

Using the mobile seedbed, only one road needs to be reserved for each span in the greenhouse, thus greatly saving the use area of the greenhouse and enabling the utilization rate of the greenhouse to reach more than 80%.
