Embodiment Construction

[0028] (1) Processing method 1

[0029] 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.

[0030] 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.

[0031] 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 method for multi-layer breeding of seedlings by using a heating incubator, belonging to a method for cultivating plant 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. Put the seedling box on the seedling rack, fill the seedling box with a 15cm thick seedling substrate, and pour it with 2000 times of carbendazim solution, insert the cut cuttings into the substrate after treatment, and keep the temperature in the box at 27-29°C , every 8‑10 days, the seedling box is poured with a 2000-fold carbendazim solution once to keep the substrate in the box moist. The seedling time is 30-40 days, and the incubator seedlings are obtained. The method of the invention has a seedling rooting rate of more than 92.0%, a large number of root systems and even distribution, secondary lateral roots, and relatively mature root development. Compared with flat seedling raising, multi-layer seedling raising increases the number of seedlings per unit area, which is suitable for factory breeding of seedlings.

Description

[0001] 1. Technical field [0002] The invention relates to a method for multi-layer breeding of seedlings by using a heating incubator, which belongs to the cultivation method of plant 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 green branches), 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 ren...
