Embodiment 1

[0068] The present embodiment paulownia root burying seedling raising technology comprises the following steps.

[0069] 1), site selection and site preparation.

[0070] Choose a nursery site with flat terrain, convenient irrigation and drainage, deep soil, fertile soil, and a groundwater level of 1.5-2.0 meters in a leeward and sunny place; After thawing in the spring of the second year, carry out shallow plowing, fine harrowing, and level the land; Iron 10kg.

[0071] 2), select the root.

[0072] The seed root used for seedling selection is 2-year-old seedling root, the length of the seed root is 12 cm, and the thickness of the big head is 1.5-2.5 cm.

[0073] 3), seed root collection.

[0074] 4) Collect the seed roots from late February to mid-March. After the roots are dug out, cut them into root cuttings according to the predetermined length in time.

[0075] Pick roots and plant roots in autumn, and store them after digging them out. Choose a leeward, sunny place...

Abstract

The invention provides a method for paulownia root burying seedling growing. By integrating nursery field selection, soil preparation, seminal root selection, root growing, bud forcing treatment, cold frame bud forcing, hotbed bud forcing, seedling management, water fertilizer application, pest control and other links, the mature technology is explored, the paulownia propagation coefficient is greatly increased, the seedling growing period is shortened, the survival rate is increased, the seedling growing cost is lowered, and paulownia seedling growing is achieved.

Description

technical field [0001] The invention belongs to the technical field of forestry, and in particular relates to a method for raising seedlings of paulownia by burying roots. Background technique [0002] Paulownia (Latin name: Paulownia.), aliases: white flower paulownia, large fruit paulownia, empty paulownia, etc. Bark gray, taupe or gray black, smooth when young, longitudinally cracked when old.
