Common preparation

Materials required

Solution A: 125g calcium nitrate and 12g ferrous sulfate. Add the above to 1kg of water

Liquid B: 37G magnesium sulfate; Ammonium dihydrogen phosphate 28 g; Potassium nitrate 41 g; Boric acid 0.6 g; Manganese sulfate 0.4 g; Copper sulfate 0.004 g; Zinc sulfate 0.004 G. Add the above to 1kg of water

Preparation process

1. Weigh various fertilizers and put them on clean containers or plastic film bags and plastic film bags spread on the ground for use

2. When mixing dissolved fertilizers, pay strict attention to the order. Calcium nitrate cannot be mixed with several fertilizers other than potassium nitrate, such as sulfate such as magnesium sulfate and ammonium dihydrogen phosphate, so as to avoid calcium precipitation

3. The dissolution sequence of tank a fertilizer: first dissolve ferrous sulfate with warm water, then dissolve calcium nitrate, and stir while adding water until the dissolution is uniform; In tank B, dissolve magnesium sulfate first, then add ammonium dihydrogen phosphate and potassium nitrate successively, add water and stir until completely dissolved, add boric acid after dissolving in warm water, and then add other trace element fertilizers respectively. A. B. mix the two liquid tanks separately and then use them for standby

4. When using nutrient solution, first take 10ml of mother liquor in tank a and dissolve it in 1kg water, and then add mother liquor in tank B to 1kg water
