Embodiment 1
[0016] A method for cultivating strawberry seedlings, specifically comprising the following steps:
[0017] (1) Pretreatment of seeds: After the strawberry seeds are sterilized by a potassium permanganate solution with a mass fraction of 0.05-0.1%, they are placed at room temperature and air-dried naturally;
[0018] (2) Seed germination: Soak the air-dried seeds in hot water at 40-44°C for 1.5-2h, after natural cooling, soak in water at room temperature for 15-20h, take out and drain, and spray water-retaining water with a mass fraction of 0.5-0.8% solution, and then placed on a germination machine at 25-28 ° C to keep warm and accelerate germination until the seeds grow white spots;
[0019] (3) Sowing on demand: Sow the germinated seeds into the culture medium, and control the depth of sowing to 1-2cm. After the sowing is completed, cover 10% of fine soil with a thickness of 0.3-0.5cm, and use straw mats for shade, and wait for the Sprinkle after the seedlings, and then sp...
Embodiment 2
[0025] Embodiment 2 differs from Embodiment 1 in that the weight parts of the raw materials in the culture medium and the special nutrient solution for strawberry seedling cultivation are different, and other conditions are the same.
[0026] The medium is composed of the following raw materials in parts by weight: 20 parts of vermiculite, 11 parts of straw, 8 parts of volcanic rock, 6 parts of distiller's grains, 5 parts of aloe residue, 5 parts of peat, 3 parts of phosphate rock powder, humic acid 2 servings.
[0027] The special nutrient solution for growing strawberry seedlings consists of the following raw materials in parts by weight: 5 parts of calcium nitrate, 2 parts of potassium nitrate, 4 parts of monoammonium phosphate, 2 parts of potassium sulfate, 3 parts of potassium chloride, 0.7 parts of boric acid, manganese sulfate 0.5 parts, sodium chloride 1.2 parts, humic acid 1 part.
Embodiment 3
[0029] Embodiment 3 differs from Embodiment 1 in that the weight parts of the raw materials in the culture medium and the special nutrient solution for strawberry seedling cultivation are different, and other conditions are the same.
[0030] The medium is composed of the following raw materials in parts by weight: 22 parts of vermiculite, 11 parts of straw, 9 parts of volcanic rock, 5 parts of distiller's grains, 4 parts of aloe residue, 6 parts of peat, 4 parts of phosphate rock powder, humic acid 2 servings.
[0031] The special nutrient solution for raising strawberry seedlings consists of the following raw materials in parts by weight: 5 parts of calcium nitrate, 2 parts of potassium nitrate, 3 parts of monoammonium phosphate, 1 part of potassium sulfate, 2 parts of potassium chloride, 0.8 part of boric acid, manganese sulfate 0.5 parts, sodium chloride 1.7 parts, humic acid 1 part.
