Problems solved by technology

[0002] The main problem affecting mulberry planting and sericulture in the northern region is how the mulberry trees survive the winter. At present, there are no large-leaf mulberry trees that can survive below minus 30°C. Therefore, the breeding industry of mulberry silkworms in the northern region has been greatly restricted, and only a very small number of them are raised. tussah silkworm

Embodiment 1

[0017] Cold region mulberry tree grafting method, the technological process is:

[0018] (1) Adopt the wild mulberry seed of northeast cold region to cultivate, select the seedling root that does not have frostbite, frostbite, well-developed roots as cold-resistant rootstock, adopts the mulberry bar through three times of winter training as scion to carry out grafting;

[0019] (2) the mulberry seedling after grafting is placed on the environment of temperature 22-25 ℃, humidity 75% and carries out nursery stock germination;

[0020] (3) The seedlings after the successful germination are moved into the nursery base plantation after fertilization, 30,000 plants per mu, row spacing 25cm, plant spacing 3-5cm, covered with plastic film for 20-30 days;

[0021] (4) Carry out weeding and field management in the nursery for one year.

Abstract

The invention relates to a method for grafting mulberries in cold regions. The main problem influencing mulberry farming and silkworm rearing in northern areas is the mulberry breeding in winter. At present, grandifoliate mulberries which can survive below the temperature of 20 DEG are not available so silkworm breeding industries in the northern areas have larger restrictions, and tussahs are bred in only a few areas. The process of the invention comprises the following steps of: (1) breeding wild mulberry seeds in northeast cold regions, selecting and using well-developed seeding roots having no freezing injury and cold injury as cold resistance root stocks, and adopting mulberry shoots subjected to three times of winter training as scion to graft; (2) putting the grafted mulberry seeding into the environment with the temperature of 22-25 DEG temperature and the humidity of 75% to carry out seeding germination; (3) moving seeding stocks successfully germinated into fertilized nursery bases to plant, wherein three million seeding stocks are planted in the nursery base per mu by keeping the line spacing of 25 cm and the row spacing of 3-5 cm, and covering the seeding stocks by plastic films for 20-30 days; (4) and performing nursery base weeding and field management for about one year. The method can be used for breeding the mulberries with strong cold resistance.

Description

Technical field: [0001] The invention relates to a method for grafting mulberry trees, in particular to a method for grafting mulberry trees capable of resisting cold in alpine regions. Background technique: [0002] The main problem affecting mulberry planting and sericulture in the northern region is how the mulberry trees survive the winter. At present, there are no large-leaf mulberry trees that can survive below minus 30°C. Therefore, the breeding industry of mulberry silkworms in the northern region has been greatly restricted, and only a very small number of them are raised. tussah silkworm. Invention content: [0003] The purpose of the present invention is to provide a method for grafting mulberry trees in cold areas, which can produce mulberry trees with strong cold resistance, high leaf yield and fast growth rate, and the process is simple, the material distribution is wide, and the purchase is convenient. Fast and efficient. [0004] Above-mentioned purpose r...
