Efficient and energy-saving forestry seedling cultivation device

The utility model discloses an efficient and energy-saving forestry seedling cultivation device which comprises a fixing shell, a cultivation box is inserted into the top of the fixing shell, the surface of the cultivation box is fixedly connected with the inner wall of a top plate of the fixing shell, and an opening is formed in the top of the cultivation box. According to the high-efficiency energy-saving forestry seedling cultivation device, water is continuously retained below cultivation soil through the sponge plate and the sponge column, and the water level in the fixed shell is flush with the water level in the cultivation box through the liquidity of liquid water, so that it is guaranteed that the cultivation soil can continuously retain water through the sponge plate and the sponge column; meanwhile, by means of vertical pushing of a pushing rod and the principle of gas pressure intensity, water in a fixed shell is sucked into a buffer pipe through an expanding and collectingfunnel and a suction pip
