Plant seedling pot allowing automatic liquid absorption

The invention discloses a plant seedling pot allowing automatic liquid absorption. According to the technical scheme, an outer pot is placed on a liquid storage pool with a nutrient solution; liquid storage substrates are placed on the lower portion of the outer pot; one end of a liquid absorption rope is placed in the liquid storage substrates and the other end of the liquid absorption rope is placed in the nutrient solution; a root system blocking net is placed on the liquid storage substrates; an inner port is compressed to be placed on the root system blocking net which is arranged in the outer pot; culture substrates are placed in the inner pot. According to the plant seedling pot allowing the automatic liquid absorption, the nutrient solution can automatically enter into the liquid storage substrates due to the liquid absorption rope and accordingly the automatic supply of the nutrient solution for a plant is achieved, the root system can be located in the ventilation state for a long time, and the plant can root new roots and branch to flourish; the double pots are overlaid with each other to fix the root system blocking net so as to effectively prevent the root system of the plant from growing along the liquid absorption rope and entering into the liquid storage pool; the outer pot can be removed when a plant seedling is transplanted, people can push upward from the bottom of the inner pot to take out the plant seedling easily without hurting the root of the plant, and accordingly the survival rate of plant transplanting is improved.
