Embodiment Construction
[0016] In order to make the object, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.
[0017] A method for cultivating oat seedlings, comprising the following steps:
[0018] (1) Culture equipment: choose a plastic cup with a diameter of 9.5cm and a height of 10.5cm, and use tweezers to burn 12 to 15 small holes (1mm×2mm) of uniform size under an alcohol lamp, so that water can enter the sand culture through the small holes medium.
[0019] (2) Culture substrate: sieve the sand with a sieve of 1mm×1mm particle size, then wash the sieved sand under tap water for 5-6 times, wash away impurities, and then dry it for later use.
[0020] (3) Sterilization: Sterilize the sand and plastic cups in an autoclave at 121°C for 30 minutes, take them out after cooling down and put them in cups for later use.
[0021] (4) Seed preparation: select plump and uniform seeds, soak them in ta...

The invention discloses a cultivation method of oat seedlings. The method comprises the following steps: selection of a cultivation tool; medium cultivation: sand is sieved through a sieve and washedby tap water 5-6 times, and the sand is subjected to air drying for standby application; sterilization: the sand and the cultivation tool are sterilized; seeds are selected, soaked overnight, washed with anhydrous ethanol, treated with a sodium hypochlorite solution, washed with sterile water and subjected to air drying for standby application; the air-dried sand is put into the cultivation tool,the cultivation tool is then put into a basin to absorb water overnight, and the sterilized oat seeds are sown evenly in the culture tool by spot seeding; planted oat is put in an artificial climate incubator under 16 hours of light and 8 hours of darkness, seedlings emerge in 3 days after the oat is planted and are cultivated with a 1 / 2 Hoagland nutrient solution when growing to 2-3 leaves, the nutrient solution is changed every 3 days, and robust seedlings can be cultivated. The cultivation method is not limited by time and place, the cultivated oat seedlings emerge quickly and neatly, and thus, the practicable, convenient and quick seedling cultivation method is provided for the oat seedlings.
Description
technical field [0001] The invention relates to the technical field of agricultural production, in particular to a method for cultivating oat seedlings. Background technique [0002] Oat is a plant of the genus Avena in the grass family. It has the characteristics of being cold-loving, cold-resistant, drought-resistant, salt-alkali-resistant, and barren-resistant. It is a low-sugar, high-nutrition, high-energy food. It is mainly distributed in northeast, north, southwest and northwest China. It is an important grain-forage crop in the development of agriculture and animal husbandry in my country. Its cultivation area accounts for about 70% of the artificial grass area on the Qinghai-Tibet Plateau in the alpine region of the Qinghai-Tibet Plateau. The annual oat planting area in Qinghai Province is more than 2 million mu , playing an irreplaceable and important role in grassland establishment in alpine pastoral areas. Therefore, paying attention to and ensuring the quality and...
