Embodiment 1

[0027] The main components of the spinach hydroponic nutrient solution per 1000ml: (1) calcium nitrate tetrahydrate 349.00mg (2) potassium nitrate 265.00mg (3) ammonium nitrate 54.00mg (4) ammonium sulfate 118.00mg (5) magnesium sulfate heptahydrate 260.00mg (6) Iron sulfate 10.0mg.

Embodiment 2

[0029] The main components of the spinach hydroponic nutrient solution per 1000ml: (1) calcium nitrate tetrahydrate 347.00mg (2) potassium nitrate 266.00mg (3) ammonium nitrate 53.00mg (4) ammonium sulfate 119.00mg (5) magnesium sulfate heptahydrate 258.00 mg (6) Iron sulfate 9.5 mg.

Embodiment 3

[0031] The main components of the spinach hydroponic nutrient solution per 1000ml: (1) calcium nitrate tetrahydrate 350.00mg (2) potassium nitrate 263.00mg (3) ammonium nitrate 56.00mg (4) ammonium sulfate 116.00mg (5) magnesium sulfate heptahydrate 262.00 mg (6) Iron sulfate 9.6 mg.

[0032] The specific method of using the spinach hydroponic nutrient solution is to first dissolve the compounds of macroelements and trace elements in the formula in water, mix them evenly, and constant volume to make a mother solution with a concentration of 100-200 mg / l, and store them at room temperature at 20-20 mg / l. Store at 25 degrees for later use. When in use, the prepared mother liquor is mixed with water at a ratio of 1:100 to obtain the spinach hydroponic nutrient solution. Spinach plants grow slowly, and the nutrient solution needs to be replaced regularly. The water should be changed every 5-10 days in spring and autumn; the water should be changed every 5 days in summer;

Abstract

The invention provides a hydroponic nutrient solution for spinach, and belongs to the technical field of soilless culture. The nutrient solution contains a large number of elements and trace elements required by plant growth. 100ml of the nutrient solution mainly contains: (1) 347.00 to 350.00mg of calcium nitrate tetrahydrate; (2) 263.00 to 266.00mg of potassium nitrate; (3) 53.00 to 56.00mg of ammonium nitrate; (4) 116.00 to 119.00mg of ammonium sulfate; (5) 258.00 to 262.00mg of magnesium sulfate heptahydrate; and (6) 9.5 to 10.0mg of ferric sulfate. The nutrient solution provided by the invention is complete in nutritional ingredients, simple to prepare and high in practicability, and can solve the problem of imbalanced nutrient supply in the common nutrient solution and promote the spinach to grow normally. Therefore, the nutrient solution has a great practical popularization value in the hydroponic field of spinach.

Description

technical field [0001] The invention belongs to the field of soilless cultivation, and relates to a spinach hydroponic nutrient solution, which is specially used for spinach hydroponic cultivation. Background technique [0002] Hydroponics is a new type of soilless plant cultivation, also known as nutrient liquid culture. Its core is to fix the plant rhizomes in the planting basket and let the roots naturally hang into the plant nutrient solution. This nutrient solution can replace the natural soil to Plants provide growth factors such as water, nutrients, oxygen, and temperature, so that plants can grow normally and complete their entire life cycle. This kind of plant cultivation technology that reflects advanced productivity has the advantages of intensive, large-scale and precise production, and the hydroponic plants cultivated by this soilless cultivation technology are more famous for their cleanliness, elegant style, strong ornamental value, The advantages of environm...
