Embodiment 1
[0030] The invention discloses a preparation method of a hydroponic nutrient solution for bromeliads in the vegetative growth period.
[0031] First, weigh 400g of calcium nitrate, 500g of potassium nitrate, 120g of ammonium nitrate, 100g of potassium dihydrogen phosphate, 250g of magnesium sulfate, 3.36g of boric acid, 18g of EDTA-2NaFe, MnSO 4 4H 2 O 3.12g, ZnSO 4 ·7H 2 O 0.38 g, CuSO 4 ·5H 2 O 0.08 g, (NH 4 ) 6 Mo 7 o 24 4H 2 O 0.06 g, indole acetic acid 0.08 g, naphthalene acetic acid 0.12 g, carbendazim 20 g, polyoxin 15 g, dissolve it in 10L of water, stir until completely dissolved, and then use a pH meter to measure the pH of the solution value, according to the actual situation, add 100g of phosphoric acid to adjust its pH value to 6.5, then add water to make it 1m 3 .
Embodiment 2
[0033] The preparation method of the hydroponic nutrient solution of pineapple flower in reproductive growth period.
[0034] First weigh 500g of calcium nitrate, 500g of potassium nitrate, 100g of ammonium nitrate, 150g of potassium dihydrogen phosphate, 120g of potassium sulfate, 200g of magnesium sulfate, 5.36g of boric acid, 21g of EDTA-2NaFe, MnSO 4 4H 2 O 3.12g, ZnSO 4 ·7H 2 O 0.38 g, CuSO 4 ·5H 2 O 0.08 g, (NH 4 ) 6 Mo 7 o 24 4H 2 0.06 g, carbendazim 20 g, and polyoxin 20 g are dissolved in 10 L of water, fully stirred until fully dissolved, then the pH value of the solution is measured with a pH meter, and 200 g of citric acid is added according to the actual situation to dissolve it. Adjust the PH value to 7, then add water to make up to 1m 3 .
Embodiment 3
[0036] A method for carrying out hydroponics to bromeliads, comprising the steps of:
[0037] (1) Select a robust pineapple plant, dig it out with roots from the culture medium, soak it in water for 20 hours, wash off the large pieces of soil with large water first, and then swing the roots back and forth in the water, Let some attached small pieces of soil fall off, and finally pick off the soil inside the roots a little by hand; wash the roots with water 4 times in a row to completely clean the roots;
[0038] (2) After washing, trim the roots, cut off all the intricately intertwined roots, keep 60% of the roots, and dry them in air;
[0039] (3) Disinfection: Soak the repaired roots in 1% potassium permanganate solution for 10 minutes;
[0040] (4) Domestication: Put the sterilized bromeliads in a bottle filled with clean water for 7 days to adapt to the breeding environment in the water;
[0041] (5) After the domestication is completed, transfer it to a vase containing ...
