Embodiment Construction

[0026] (1) Processing method 1

[0027] 1. The preparation of the nursery site: the required nursery site for this method is in a plastic greenhouse. The plastic greenhouse has the characteristics of heat preservation, rain and snow protection, which is beneficial to reduce power consumption, and is easy to operate and manage.

[0028] 2 Production of seedling raising frame: welded with triangle iron to form a frame of 2.2m×1.2m×1.6m. 3-layer structure, the height of the feet is 20cm, the distance between each layer is 70cm, and a seedling box is placed on each layer.

[0029] 3 Heated seedling raising box production: the seedling raising box is made of color steel composite board with a thickness of 5.0cm, and the outer diameter, length, width and height of the box body are 210cm, 110cm and 30cm respectively. Connect two geothermal wires with a specification of 33 ohms / m in parallel at an interval of 5 cm, spread the bottom of the box along the longitudinal direction of the...

Abstract

The invention relates to a heated hollow seedling cultivation box and an application thereof, belonging to a method for cultivating forest seedlings. A box with a bottom inner diameter of 200cm×100cm and a height of 30cm is made of color steel composite board, and a geothermal wire with a resistance of 33 ohms / m is laid on the bottom of the box to form a heated and temperature-controlled seedling box. Three expandable polystyrene foam boards with a length, width and height of 199cm×3cm×10cm are erected on both sides and in the middle of the seedling box, and the cover plates of the seedling box of 99cm×3cm×10cm are laid on them in turn, and the sides are paved. Insert the cuttings in the small semicircular groove, the base of the cuttings should be in contact with the black mulch film, and the two adjacent small grooves of foam boards are connected to each other to clamp the cuttings until the entire seedling box is filled. The method of the invention has a seedling rooting rate of more than 95%, a large number of root systems and even distribution, secondary lateral roots, and relatively mature root development. Compared with conventional seedbeds, the rooting rate and the number of roots per plant are greatly improved, and more importantly, more than 80% of the substrate is saved, which greatly reduces the cost of seedling cultivation.

Description

[0001] 1. Technical field [0002] The invention relates to a heated hollow seedling cultivation box and its application, which belongs to a method for cultivating forest tree seedlings, and is specially used for the breeding of seedlings. [0003] 2. Background technology [0004] The breeding methods of mulberry seedlings are divided into two categories: sexual reproduction and asexual reproduction. Asexual reproduction can maintain and continue the excellent traits of the parents, and its methods mainly include grafting, cuttings (hard branches and twigs), layering, etc. [0005] The use of grafting (bag grafting) to propagate mulberry seedlings currently occupies an absolutely dominant position in my country. At present, the main production areas of mulberry seedlings in my country are concentrated in 5-6 counties in Jiangsu and Zhejiang provinces. In normal years, more than 1 billion grafted mulberry seedlings are produced, supplying new planting and renewal of mulberry g...
