Planting methods of Strawberry Seeds

Strawberry is a perennial herb of the genus strawberry in Rosaceae. The propagation methods include seed propagation and plant division propagation, which are often used in production. Seed propagation is more often used for long-distance introduction or cultivation of strawberry seedlings to select new varieties. It can also be used for courtyard greening and fresh food planting. Let's take a look at the planting method of strawberry seeds.

Seed collection

During the fruit harvest from May to June, the well-developed and fully mature fruits were selected for seed collection, peeled off, put into water, washed, removed and dried. Or dry the peel directly, then crush it, and then separate the peel from the seed.

Seed treatment

Wash the strawberry seeds in 60-70 ℃ warm water and keep stirring until the water temperature drops to about 25 ℃. Soak for another 2-3 hours, remove and rub with hands until the seed coat is clean and shiny. Then rinse with clean water and cover with several layers of wet gauze. Germinate under the condition of 25: 30 ℃, soak the gauze with warm water three times a day (morning, noon and evening) to maintain the moist environment of the seeds, and sow seeds after 60: 70% of the seeds are white.

Sowing method

Before sowing strawberry seeds, irrigate the border with small water, then rake the border surface, and then sow when the border seeps under water. The seed of strawberry is small, so it is better to sow it. The appropriate sowing rate is 2.5-4.5 grams per square meter. immediately after sowing, spread the mulch evenly on the border surface with a thickness of 0.3-0.5 cm, shade with straw mats and scatter after finishing the seedlings.

Seedling land preparation

Strawberry nursery land is selected from fertile soil and applied sufficient base fertilizer, which is dried with manure, and then mashed and applied to the seedling field that has yet to be ploughed. The amount of fertilizer applied is 5 jin per square meter, and compound fertilizer should be added appropriately. After fertilizing, careful ploughing should be carried out, and the depth can be about 33 cm. After ploughing, it is necessary to rake fine and flat, and make ridges according to a width of 0.8 meters and a length of 8 meters, so as to make the border horizontal, so as to facilitate drainage and irrigation and management.

Seedling stage management

1. Watering: strawberry seedlings are not suitable for flooding irrigation, sprinkler irrigation can be used to meet the water supply, and small water flooding irrigation can be used after 6 true leaves.

2. Weeding: strawberries should always pull out weeds in time at the seedling stage.

3. Replenishing seedlings: strawberry seedlings can be transplanted with 3 or 5 true leaves.

4. Topdressing: when strawberry seedlings grow to 6 true leaves, topdressing can be carried out for the first time, and urea is suitable for topdressing.
