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 method for raising seedlings of du pear seeds, comprising the following steps:

[0030] (1) In the maturity season of the du pear fruit, collect the big, bright, full-grained, disease-free fruits from the mother plant with good fruiting performance and no pests and diseases for 3 days. After the skin is soft, peel off the flesh. Seeding

[0031] (2) Disinfection and soaking of seeds: spread the collected seeds in a ventilated and shaded place, dry for 3 days, soak the collected seeds in a 0.1% mercury solution by mass for 7 minutes for disinfection, then rinse the seeds with clean water, and then the seeds Pour into 100℃ boiling water, stir continuously until the water temperature drops below 50℃, then cover, soak in water for 24h, and cool naturally;

[0032] (3) Pit and retreat seeds: first put the seeds obtained in step (2) in clean water and continue to soak for 4 days, and then mix the above seeds with plant growth regulators (6-BA110ppm, naphthalene acetic acid 80ppm,...

Embodiment 2

[0076] The seeds of Du Pear are processed as follows:

[0077] (1) In the maturity season of du pear fruit, collect large, bright, full-grained, disease-free fruits from the mother plant with good fruit performance and no disease and insect pests during the peak season. After the skin is soft, peel off the flesh. Seeding

[0078] (2) Disinfection and seed soaking: spread the collected seeds in a ventilated and shaded place, dry for 3 days, soak the collected seeds in a 0.2% mercury solution by mass for 5 minutes for disinfection, then rinse the seeds with clean water, and then the seeds Pour into 100℃ boiling water, stir continuously until the water temperature drops below 50℃, then cover, soak in water for 24h, and cool naturally;

[0079] (3) Pit and retreat: first put the seeds obtained in step (2) in clean water and continue to soak for 6 days, then mix the plant ash containing plant growth regulators in the above seeds, and dig a half-meter deep hole for retting. Spread a laye...

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, and specifically relates to a seedling raising method of Du Pear. Background technique [0002] Pyrus betulifolia Bunge (Pyrus betulifolia Bunge) is a deciduous tree in the Rosaceae family, and its branches often have thorns. The plant is 10 meters high and the branches are thorny. The leaves are rhomboid-ovate to oblong, umbellate racemes, with 10-15 flowers, white petals, and 2-3 styles. The fruit is nearly spherical, brown, flowering in April and fruiting in August to September. Du pear is resistant to drought, cold and cold, and is usually used as the rootstock for various cultivated pears. It has an early fruiting period and a long life span. The dense wood can be used as various utensils. The bark contains tannins, which can be extracted and used as medicine. [0003] In the cultivation and breeding of pear trees, grafting is basically used to raise seedlings, that is, rootstock seeds are sown firs...
