Embodiment 1

[0017] Purify the Shapotou sand rice seeds, pour the Shapotou sand rice seeds into a beaker, rinse them with clean water, remove dead branches, broken leaves, sand and other impurities inside, and select plump, insect-free and non-damaged ones Sand rice seeds, sterilized with 10% sodium hypochlorite, soaked seeds for 5min, rinsed with distilled water and dried, and then washed with 2g / L GA 3 After soaking the seeds for 24 hours, drill them in the seedling field. The soil is sandy soil, the length of the strip is 50cm, and the thickness of the sand cover is 1-2cm. Each strip has 30 seeds. The shading rate of the sunshade net is 90%, pour water once after 3 days, and it can germinate in 5-6 days. Remove the sunshade net, water and moisturize, so that the seedlings can adapt to the natural state of growth. After 1-2 months, the seeds will germinate 2-4 true leaves, with more than four branches, and the plant will reach a height of 5-15cm, basically meeting the needs of sand rice...

Embodiment 2

[0019] Purify the seeds of Naiman Sami, pour the seeds of Naiman Sami into a beaker, rinse them with clean water, remove dead branches, broken leaves, sand and other impurities inside, and select full, pest-free and non-damaged Sami Seeds are sterilized with 10% sodium hypochlorite, soaked for 5 minutes, rinsed with distilled water and dried, then soaked with 2g / L GA3 for 24 hours, and drilled in the seedling field. The soil is sandy soil with a strip length of 50 cm and a thickness of 1 ~2cm, 30 seeds per seedling, water and moisturize after sowing, cover a layer of sunshade net 1m above the seedling ground, the shading rate of the sunshade net is 90%, water once after 3d, and germinate after 5-6d. Part of the sunshade net was removed after germination, and the seed germination rate reached 84.4% on the 10th day. When there was no light at night, the sunshade net was removed, watered and moisturized, so that the seedlings adapted to the natural state growth. After 1-2 months,...

Embodiment 3

[0021] Purify the Minqin sand rice seeds, pour the Minqin sand rice seeds into a beaker, rinse them with clean water, remove dead branches, broken leaves, sand and other impurities inside, and select full, pest-free and damage-free sand rice Seeds, sterilize the selected sand rice seeds with 10% sodium hypochlorite, soak the seeds for 5min, then rinse and dry them with distilled water, and then use 2g / L GA 3 After soaking the seeds for 24 hours, drill them in the seedling field. The soil is sandy soil, the length of the strip is 50cm, and the thickness of the sand cover is 1-2cm. Each strip has 30 seeds. The shading rate of the sunshade net is 90%, water once after 3 days, and it can germinate in 5-6 days. Remove the sunshade net, water and moisturize, so that the seedlings can adapt to the natural state of growth.

Abstract

The invention discloses a sand-fixing vanguard plant sand rice germplasm resource propagation technology, the sand rice seeds are purified, the dead branches, broken leaves, and sand impurities are removed, and plump, insect-free and damage-free sand rice is selected Seeds; soak seeds with 10% sodium hypochlorite for 5‑10min to sterilize, rinse and dry with distilled water; place seeds in dark conditions and soak them with 2g / L GA3 for 24h to break the dormancy of sand rice seeds; sow seeds in strips to seedlings Medium, covered with 1-2cm thick silt soil after sowing; watered to moisturize and cover a layer of sunshade net 1m above the seedling field; germinated after sowing 5-6d, part of the sunshade net was removed at night, watered and moisturized; 10- 15d stop seedling emergence, throw off all sunshade nets at night, water and moisturize. The invention can effectively break the dormancy of the sand rice seeds, has the advantages of simplicity, convenience, quickness and effectiveness, can propagate a large number of seedlings in a short time and can provide materials needed for realizing the edible and forage sand rice germplasm resources.

Description

technical field [0001] The invention relates to the technical field of plant propagation, in particular to a technique for multiplying germplasm resources of sand-fixing pioneer plant Amygdalus sativa. Background technique [0002] Agriophyllum squarrosum (Agriophyllum squarrosum) is an annual herb of Chenopodiaceae. It grows in moving sandy land and semi-fixed sandy land. It is a typical psammophyte and a pioneer plant for sand-fixing. Natural green food, rich in essential amino acids such as crude protein, crude fat, threonine, methionine, lysine, and mineral elements such as magnesium, potassium, zinc, etc., helps to promote digestion, strengthen the spleen and stomach, etc. Good development and utilization value. However, the development and utilization of existing sand rice jelly etc. all come from wild sand rice, and it is urgent to carry out the artificial cultivation and propagation of good sand rice germplasm resources. As an annual plant, the only way to reproduc...
