Embodiment 1
[0044] A hydroponic substrate for cultivating blueberry seedlings, comprising 1 part by mass of a bactericidal solvent, 1 part by mass of an acid-adjusting solvent, 1 part by mass of a fertilizer-increasing solvent, and 1 part by mass of a rooting solvent.
[0045] Wherein the sterilizing solvent includes 5 parts by mass of garlic, 3 parts by mass of mugwort, 2 parts by mass of pokeweed, 3 parts by mass of scutellaria, 2 parts by mass of Scutellaria barbata, and 5 parts by mass of mountain pepper;
[0046] The acid adjusting solvent comprises 2000 parts by weight of pineapple extract, 4 parts by weight of fumaric acid and 100 parts by weight of ammonium sulfate.
[0047] The fattening solvent includes 0.375g / L natural seaweed extract, 0.2g / L seaweed polysaccharide, 2.5g / L aminopeptide, 1.5g / L P 2 o 5 , 1.25g / L calcium, 0.1g / L magnesium, 2.5g / L zinc, 2.25g / L boron, 0.05g / L EDTA-Fe, 0.0175g / L EDTA-Cu, 0.00125g / L of EDTA-Mo, 0.0005g / L of EDTA-Co; 20g / L of potassium dihydrogen ...
Embodiment 2
[0061] A kind of earth culture matrix that is used for blueberry seedling hardening, comprises 1300 weight parts mixed soils, 0.3 weight part terminalia leaf, the sulfur of 0.35 weight part, the compost rapid decomposing agent of 0.2 weight part (the compost decomposing agent is bought in Guangxi Zhuang Agriculture and Animal Husbandry Technology Co., Ltd., product name: Dabida). The mixed soil includes peat soil, laterite, perlite, sawdust, and pine needles, and its volume ratio is 4:2:3:2:1.
[0062] The preparation method of the earth culture substrate that is used for blueberry seedling hardening of the present embodiment, comprises the following steps:
[0063] (1) Preparation of mixed soil: peat soil, laterite, perlite, sawdust and pine needles were mixed according to the volume ratio of 4:2:3:2:1 to obtain the mixed soil.
[0064] (2) per 1m 3 Add 300g of terminal kernel leaves, 350g of sulfur, and 200g of compost rapid decomposing agent to the mixed soil. After mixin...
Embodiment 3
[0066] An application of the hydroponic medium of Example 1 and the soil culture medium of Example 2 in hardening blueberry seedlings. The blueberry tissue-cultured seedlings of this example adopt the variety "Jietu". Its application method includes the following steps:
[0067] (1) Preparation work:
[0068] 1. Selection of tissue culture seedlings: select tissue culture seedlings with strong growth and good growth, and the plant height of the seedlings out of the bottle is 8-10 cm. (The height of the plant refers to the height of the tissue cultured seedlings from the top bud to the root) Move the selected tissue cultured seedlings from the light cultivation room to the greenhouse, seal the bottle cap and harden the seedlings for 1 day, loosen the bottle cap and harden the seedlings for 1 day, so that Gradually adapt to the outdoor environment.
[0069] 2. Preparation of seedling hardening plugs: take 200-hole polystyrene foam boards, seal and connect the bottom to form a ...
