Rapid Propagation of Cherry Seedling

1. Prepare the ground to make a nursery bed

In the middle and last ten days of April, sandy loam with good drainage was selected and 2000-3000 kg of high-quality soil and miscellaneous fertilizer was applied every 667 square meters (1 mu). Then make the bed, which is 1 meter wide and 15-20 meters long, and disinfect the soil with 200 times ferrous sulfate solution (50 kg per square meter).

two。 Seed treatment

In the first and middle of May, pick ripe cherries, remove meat and wash, circle with No. 8 wire into a small circle with a diameter of 1.5cm, place the seeds in the circle, gently smash off the shell, then put the seeds in 40 ℃ of warm water and keep stirring. When it drops to 20 ℃, soak for 24 hours.

3. Sowing and covering film

Before sowing, fill the border with enough water. after soaking, sow 1000 seeds per square meter and cover with fine sand 1 centimeter thick, then build a small arch shed 60 centimeters high, cover it with film, and finally cover it with grass curtains.

4. Seedbed management

Cover the straw curtain at 8 o'clock in the morning and open it at 5 pm every day. There is no need to cover it on a cloudy day. After 10-15 days, the buds can be unearthed. After the seed buds were unearthed, they were sprayed with water to keep moisture and cool down every 2-3 days. When the seedlings grew to 4-5 true leaves, they could be transplanted. When transplanting, the plant spacing is 10-15 cm, and the row spacing is 33 cm. After that, 0.4% urea solution was sprayed every day after 8: 00 a.m. or 5: 00 p.m. Spray for 15 days in a row. The Autumn Equinox can be grafted later.
