Blueberry fruit is rich in nutrients, with the prevention of brain nerve aging, strong heart, softening blood vessels, enhance the immune system of the human body and other functions, blueberry, a small berry, the fruit is blue, beautiful color, blue is 1 layer of white fruit powder wrapped, the flesh is delicate, the seeds are very small. Blueberry fruit average weight 0.5 ~ 2.5g, weighing 5g, edible rate, sweet and sour taste, and has a pleasant fragrance, for fresh food, today we will introduce a blueberry how to seedlings, blueberry seedling technology.
1.Using tissue culture methods to cultivate semi-high bush blueberry and dwarf bush blueberry seedlings.
Basic culture medium: WPM + ZT (0.5 ~ 1.0mg / L) + IBA0.05mg / L
Starter culture: Use stem tip or stem segment, use 75% alcohol for 30s, then 0.1% ascending mercury for 8min, then rinse with sterile water five times, then inoculate into medium with 16h light, light intensity 2000~3000 lux, temperature about 23℃.
Proliferation culture: After the seedlings grow to the full size of the bottle, they are repeatedly transferred until the desired number.
Assessment: The bottle seedlings are qualified if they grow well, have normal color, the infection rate is controlled within 5% and the number is moderate.
After three days of bottle seedling refining, cut into about 3 cm stem segments, soak them with 800 times of carbendazim and rooting powder for 10 min, then transplant them into seedling trays filled with water moss, with temperature control at 15-28℃ and humidity at 70-90%, and shade them with shade net until the stem segments are rooted. Spray 800 times carbendazim and rooting solution every 15 days.
After rooting, move into a 12×13 cm nutrient bowl, and control the ph value of the seedling soil at about 4.5, while mixing in about 1/4 of saw foam or pine needles, etc.
Management: water moderately every day, observe the condition and insects, and prevent in time.
Assessment: rooting rate ≥ 70%, rooting survival rate ≥ 90% for qualified.
3.After the root system grows full of nutrition bowl can be moved into the field.
