Problems solved by technology

Although existing reports show that blueberry tissue culture seedlings are easier to root out of the bottle, there is still room for improvement in the rooting rate
The nutrient solution can provide sufficient mineral nutrients to promote plant growth, but searching the prior art, there is currently no blueberry hydroponic cutting technology

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...

Abstract

The invention belongs to the field of plant cultivation nutrient solutions, particularly relates to the field of blueberry soilless-scale-cutting nutrient solutions and discloses a blueberry soilless-scale-cutting nutrient solution. The blueberry soilless-scale-cutting nutrient solution is characterized in that the blueberry soilless-scale-cutting nutrient solution comprises the following elements of 0.25 mmol / L of (NH4)2SO4, 0.25 mmol / L of Ca(NO3)2, 1 mmol / L of KH2PO4, 0.5mmol / L of K2SO4, 1 mmol / L of CaCl2, 1 mmol / L of MgSO4, 19 mu mol / L of Fe(III)EDTA, 9.1 mu mol / L of MnSO4, 0.31 mu mol / L of CuSO4, 0.76 mu mol / L of ZnSO4, 0.1 mu mol / L of Na2MoO4, and 46.3 mu mol / L of H3BO3, and a pH value is adjusted into 3.5 to 6.5. By means of the blueberry soilless-scale-cutting nutrient solution, the rooting percentage of blueberry tissue culture seedlings can be increased, and rooting of blueberries is accelerated, so that increasing of the survival rate of transplanting is facilitated, effects of propagation and rejuvenation are improved, and expanded propagation is promoted.

Description

technical field [0001] The field of plant cultivation nutrient solution, especially the field of blueberry soilless cutting nutrient solution. Background technique [0002] Blueberry (vaccinium spp.), a perennial shrub of the Rhododendronaceae Vaccinium genus, the fruit is a small blue-purple berry with a unique flavor, rich in antioxidant substances such as arbutin, anthocyanin, ellagic acid and flavonoids. It has excellent effects in preventing myopia, enhancing heart function, anti-cancer, and anti-cardiovascular disease. The International Food and Agriculture Organization has recommended it as one of the five health foods for human beings. [0003] The offspring of blueberry seed propagation have a large variation range and cannot maintain the excellent characteristics of the variety. In order to maintain the excellent traits of the mother plant, the blueberry is multiplied by asexual propagation method, and the tissue culture seedlings or branch cuttings are rooted in ...
