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,...

[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 propagation technology for sand stabilization pioneer plant agriophyllum squarrosum germplasm resources. The propagation technology includes the steps that agriophyllum squarrosum seeds are purified to remove deadwood, tattering leaves and sandy soil impurities in the seeds, and full agriophyllum squarrosum seeds without insect damage or injuries are selected; the seeds are soaked in 10% sodium hypochlorite for 5-10 min to be sterilized, flushed with distilled water and aired dry; the seeds are soaked in 2 g/L GA3 for 24 h on the dark condition to break dormancy of the agriophyllum squarrosum seeds; the seeds are sowed in line in a seedling land, and covered with silty sand soil by 1-2 cm; watering is carried out to preserve moisture, and a sunshade net covers the position 1 m above the seedling land; the sown seeds sprout after 5-6 days, part of the sunshade net is uncovered at night, and watering is carried out to preserve moisture; seedling emergence stops after 10-15 days, the whole sunshade net is uncovered at night, and watering is carried out to preserve moisture. The propagation technology can effectively break dormancy of the agriophyllum squarrosum seeds, has the advantages of being easy, convenient, fast, effective, and capable of propagating a great number of seed seedlings within short time and providing materials needed by obtaining edible and feeding agriophyllum squarrosum 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 shifting sandy land and semi-fixed sandy land. It is a typical psammophyte and a pioneer plant for sand fixation. Green food rich in crude protein, crude fat, threonine, methionine, lysine and other essential amino acids and mineral elements such as magnesium, potassium, zinc, etc., helps to promote digestion, strengthen the spleen and stomach, etc., has a 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 repro...
