Air Pruning Pot is a new rapid seedling cultivation technology to regulate root growth. It has a unique effect on preventing root rot and coiling of main roots. 

    Air Pruning Pot can make the lateral root shape thick and short. It will not form winding roots and overcome the defect of root winding caused by conventional container seedling cultivation. the total root volume increases by 30-50 times, the survival rate of seedlings reaches over 98%, the period of seedling cultivation is shortened by half, and the workload of management after transplantation is reduced by more than 50%. 

    Air Pruning Pot can make the roots of seedlings strong and vigorous, especially for large seedlings cultivation and transplantation, seasonal transplantation and afforestation under harsh conditions. It has obvious advantage

1. Root-increasing effect: 

    There is a special film on the inner wall of the container for root-controlling seedling cultivation, and there are stomata at the top of the container with concave and convex sides. When the roots of the seedling grow outward and downward and contact with air (small hole on the side wall) or any part of the inner wall, the apex ceases to grow, and then three new roots sprout at the back of the apex and continue to grow outward and downward, when contacted with air.( When the hole in the lateral wall or any part of the inner wall stops growing and three new roots grow out after the apex. In this way, the number of roots increases by 3 series, which greatly increases the number of short and thick lateral roots, and the total number of roots is 20-30 times higher than that of conventional field seedlings.

2. Root-controlling effect: 

    General seedling-raising technology, the main root is too long, the lateral root development is weak. the winding phenomenon of seedling roots is very common with conventional container seedling raising method. Root-control technology can make lateral roots short and thick, and develop in large numbers. At the same time, it restricts the growth of main roots and does not form twisted roots.

3. the process of growth promotion:

     Because of the dual functions of root-controlling container and matrix, the root system of seedlings is robust and can store a large amount of nutrients to meet the growth needs of seedlings at the initial stage of planting, which creates good conditions for the survival and rapid growth of seedlings. No root injury, no head cutting, no seasonal restrictions, simple management procedures, high survival rate, fast growth.
