Embodiment 1
[0026] A. Deploy nutrient solution;
[0027] 1) To prepare a concentrated solution, add the following ingredients per liter of water: 35.5-58.5g of potassium nitrate, 11-19.5g of potassium dihydrogen phosphate, 14.5-65g of urea, 0.5-2.9g of manganese sulfate monohydrate, 0.23- 1g, boric acid 0.28-1g, potassium iodide 0.02-0.12g, sodium molybdate 0.01-0.05g, copper sulfate pentahydrate 0.01-0.05g, cobalt chloride hexahydrate 0.01-0.05g, disodium ethylenediaminetetraacetic acid (Na2EDTA) 1.5-7.5g, Ferrous Sulfate Heptahydrate 1.2-6.5g; after the concentrate is prepared, store it away from light and at room temperature.
[0028] 2) Measure the hardness of the water quality. The water source for supporting plants can be tap water after standing still or non-polluted natural water, and measure the calcium and magnesium content in the water quality of the water intake point; the water used for the above 1) preparation of the concentrate can be pure water or ) to measure the natural...
Embodiment 2
[0035] "Step A, preparing nutrient solution" in Example 1 is replaced by:
[0036] 1) Measure the hardness of water quality. The water source for supporting plants can be tap water after standing still or non-polluted natural water. First, measure the calcium and magnesium content, pH value and pH value in the water quality of the water intake point;
[0037] 2) To prepare a concentrated solution, add the following ingredients per liter of water: 35.5-58.5g of potassium nitrate, 11-19.5g of potassium dihydrogen phosphate, 14.5-65g of urea, 0.5-2.9g of manganese sulfate monohydrate, 0.23- 1g, boric acid 0.28-1g, potassium iodide 0.02-0.12g, sodium molybdate 0.01-0.05g, copper sulfate pentahydrate 0.01-0.05g, cobalt chloride hexahydrate 0.01-0.05g, disodium ethylenediaminetetraacetic acid (Na2EDTA) 1.5-7.5g, ferrous sulfate heptahydrate 1.2-6.5g;
[0038] Then add magnesium sulfate heptahydrate 0-36g / L, anhydrous calcium chloride 0-38g / L and an appropriate amount of phosphoric ...
Embodiment 3
[0041]The concentrated solution described in the above embodiment 1 or 2 can be further adjusted to include: potassium nitrate 45-50g / L, potassium dihydrogen phosphate 16-17.5g / L, urea 28.5-33.5g / L, manganese sulfate monohydrate 1.5-1.9 g / L, zinc sulfate heptahydrate 0.7-0.88g / L, boric acid 0.52-0.73g / L, potassium iodide 0.07-0.09g / L, sodium molybdate 0.02-0.03g / L, copper sulfate pentahydrate 0.02-0.03g / L L. Cobalt chloride hexahydrate 0.02-0.03g / L, disodium ethylenediamine tetraacetate (Na2EDTA) 3.5-3.8g / L, ferrous sulfate heptahydrate 2.6-3g / L.
