Embodiment Construction

[0022] (1) Processing method 1

[0023] 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.

[0024] 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.

[0025] 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 200cm, 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 heating hollow nutrient bag seedling culturing box and an application thereof, and belongs to a culturing method of forestry tree seedlings. A floor heating wire with resistance of 33ohm / m is arranged at the bottom of the box, so as to form the seedling culturing box (with outer diameter of 210cm*110cm*30cm) which can be heated and of which the temperature can be controlled; three expandable polystyrene foam plates with respective size of 199cm (length)*3cm (width)*10cm (height) are arranged at the two longitudinal edges and the middle part of the interior of the seedling culturing box, cover plates of the seedling culturing box are sequentially arranged on the foam plates, cuttings of which the roots are coated with nutrient bags are arranged in the seedling culturing box according to the positions of small grooves in the cover plates, the small grooves of the two adjacent foam cover plates are butted, and the cuttings are clamped, until the cuttings are fully arranged in the seedling culturing box; the temperature in the box is maintained at 27-29 DEG C, a 2,000-times carbendazim (50% of wettable powder) solution is applied into the seedling culturing box at the interval of 7-8 days, and the moisture of a substrate in the box is maintained; the seedling culturing time is 30-40 days, and the seedling culturing in the warm box is obtained. A method has the advantages that the rooting rate of the seedling culturing reaches more than 95%, and the seedling survival rate is high.

Description

1. Technical field [0001] The invention relates to a heating hollow nutrition bag seedling raising box and an application thereof, which belongs to a method for cultivating plant seedlings and is specially used for seedling breeding. 2. Background technology [0002] 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. [0003] 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 gardens in ot...
