Problems solved by technology

During the sand storage period, the seeds often rot due to poor control of water or ventilation conditions, or poor control of the length of low-temperature stratification time, which affects the normal release of dormancy of the seeds, resulting in the inability of the seeds to germinate or the low germination rate after sowing. For the hybrid seeds recovered through hybridization, if the seed layering is not handled well and cannot germinate, it will affect the breeding work plan

Embodiment 1

[0029] A kind of seed seedling raising method of Duli pear, comprises the following steps:

[0030] (1) During the ripening season of Duli pear fruit, from the mother plant with good fruiting performance and no pests and diseases, collect fruits with large fruit, bright color, full grains, and no pests and diseases in the sun for 3 days. After the skin is soft, peel off the flesh For seeding;

[0031] (2) Disinfection and seed soaking: spread the collected seeds in a ventilated and cool place, dry in the shade for 3 days, soak the harvested seeds in a 0.1% mercuric solution for 7 minutes for disinfection, then rinse the seeds with clear water, and then dry the seeds Pour into boiling water at 100°C, stir continuously until the water temperature drops below 50°C, then cover, soak in water for 24 hours, and cool naturally;

[0032] (3) Pit storage retting seeds: first the seeds obtained in step (2) are placed in clear water and continued to soak for 4 days, then mix in the abov...

Embodiment 2

[0076] The seeds of Duli are processed as follows:

[0077] (1) During the ripening season of Duli pear fruit, collect fruits with large fruit, bright color, full grains and no pests and diseases from the mother plant at the peak fruiting stage with good fruiting performance and no pests and diseases. After the skin is soft, peel off the flesh For seeding;

[0078] (2) Disinfection and seed soaking: spread the collected seeds in a ventilated and cool place, dry in the shade for 3 days, soak the harvested seeds in 0.2% mercuric chloride solution for disinfection for 5 minutes, then rinse the seeds with clear water, and then dry the seeds Pour into boiling water at 100°C, stir continuously until the water temperature drops below 50°C, then cover, soak in water for 24 hours, and cool naturally;

[0079] (3) Pit storage retting seeds: first put the seeds obtained in step (2) in clear water and continue soaking for 6 days, then mix the above-mentioned seeds with plant ash containi...

Abstract

The invention relates to a seed growing method for pyrus betulaefolia. The seed growing method comprises the steps of seed collection, soaking, multi-medium lamination treatment, performing sprouting cultivation through a manmade climate box and the like. By the adoption of pyrus betulaefolia seeds treated by the seed growing method disclosed by the invention, the sprouting rate is increased, and the seed treatment expense is lowered; meanwhile, the shortcomings of low seed sprouting speed and untidy seedling emerge are overcome, so that tree seeds with difficulty in seedling growing are easy to multiply and are multiplied quickly; the seed growing method is easy to popularize in production, and the sprouting rate is over 95 percent.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for raising seedlings of pears. Background technique [0002] Du pear (Pyrusbetulifolia Bunge) is a deciduous tree in the Rosaceae family, and its branches often have thorns. Plant height 10 meters, branches with thorns. Leaves diamond-shaped ovate to oblong, umbel-shaped raceme, with 10-15 flowers, white petals, 2-3 styles. The fruit is nearly spherical, brown, flowering in April and fruiting in August-September. Du pears are resistant to drought and cold, and are usually used as rootstocks for various cultivated pears. The fruiting period is early and the life span is very long. The dense wood can be used for various utensils. The bark contains tannins, which can be extracted and used as medicine. [0003] In pear tree cultivation and breeding, grafting seedlings are basically adopted, that is to say, rootstock seeds are sown earlier, cultivated into rootstock seedlings...
