How to make a flower nutrient solution

In flower cultivation (not soilless cultivation), the use of solid fertilizers is not only difficult to grasp, but also troublesome. If liquid fertilizers are used, the use of nutrient solution to grow flowers is both convenient and effective. First, several commonly used nutrient solution formulations and usage Currently, the most commonly used flower nutrient solution are the following two: (1) potassium nitrate 0.7 g / l, boric acid 0.0006 g / l, calcium nitrate 0.7 g / l, manganese sulfate 0.0006 g/L, 0.8 g/L of superphosphate, 0.0006 g/L of zinc sulfate, 0.28 g/L of magnesium sulfate, 0.0006 g/L of copper sulfate, 0.12 g/L of iron sulfate, and 0.0006 g/L of sulfuric acid hinge. Usage: When used, mix the various compounds together, add 1 liter of water, which means to become a nutrient solution and directly water the flowers. When the dosage is large, it is used with the ratio. (2) 5 g of urea, 3 g of potassium dihydrogen phosphate, 1 g of calcium sulfate, 0.5 g of magnesium sulfate, 0.001 g of zinc sulfate, 0.003 g of iron sulfate, 0.001 g of copper sulfate, 0.003 g of manganese sulfate, 0.002 g of boric acid powder, Add 10 liters of water and dissolve the nutrients. Usage: Peanuts are poured once a week for a long period of time. Each dose depends on the size of the plants. If the flowers are positive, they should be poured about 100 ml each time, and the negative flowers should be reduced. Winter or dormancy period, once every 1 month. Usually still use tap water. Second, the preparation of nutrient solution precautions (1) preparation of nutrient solution glass, enamel, ceramic and other utensils, avoid using metal containers. (2) In the preparation, a small amount of warm water at 50°C should be used to dissolve various elements, then pour it into water, stir it down and mix thoroughly. (3) When using tap water to prepare nutrient solution, a small amount of humic acid compounds should be added to treat the chlorides and sulfides in the water; rural areas should be prepared directly from river or lake water. Third, adjust the pH of the nutrient solution If the pH of the water used is neutral or slightly acidic, the pH of the nutrient solution after mixing is similar to the source of the water, so no adjustment is needed; however, if the tap water used is determined to be alkaline by a pH test paper, Phosphoric acid is used for neutralization; if strongly acidic, sodium hydroxide is added dropwise to make it neutral or slightly acidic.
