Embodiment Construction
[0010] Select well-growing stems of about 4 cm blueberry tissue culture seedlings, soak them in 1500 mg / kg IBA solution for 15 s, and then disinfect them with 800 times carbendazim for 1 h, then rinse them with water for 5 minutes.
[0011] Prepare nutrient solution, weigh (NH 4 ) 2 SO 4 16.5 g, Ca(NO 3 ) 2 29.5 g, KH 2 PO 4 68 g, K 2 SO 4 44 g, CaCl 2 110 g, MgSO 4 123 g, Fe(III)EDTA 3.48 g, MnSO 4 0.77 g, CuSO 4 0.04 g, ZnSO 4 0.11g, Na 2 MoO 4 0.01 g, H 3 BO 3 1.43g, add water to dissolve to 5 L, make 100 times mother liquor, take 100 ml from mother liquor as needed, dilute to 10 L for use.
[0012] Use a pH meter and 0.1 mol / L H 2 SO 4 Or NaOH to adjust the pH of the nutrient solution to 3.5, 4.5, 5.5, 6.5. The seedlings were transferred to the nutrient solution, and 24 seedlings were treated in each group, and repeated 3 times. The nutrient solution was inflated around the clock and replaced once a week. Begin to count the situation of blueb...
