Embodiment 1

[0030] The following substances measured in milligrams were successively fixed in a container filled with 1L of deionized water: 470 calcium nitrate tetrahydrate, 210 potassium nitrate, 65 potassium dihydrogen phosphate, 485 magnesium sulfate heptahydrate, 37 ammonium nitrate, 2.5 boric acid, Manganese sulfate 2.1, zinc sulfate heptahydrate 0.18, ammonium molybdate 0.015, copper sulfate heptahydrate 0.06, disodium iron edetate 18, citric acid 8;

[0031] After the nutrient solution is used in hydroponics of leafy vegetables, the cultivation period of vegetables is shortened by 6 days, the yield is increased by 18%, and the content of nitrate and nitrite is reduced by 70%.

Embodiment 2

[0033] The following substances measured in milligrams were successively fixed in a container filled with 1L of deionized water: calcium nitrate tetrahydrate 495, potassium nitrate 240, potassium dihydrogen phosphate 75, magnesium sulfate heptahydrate 590, ammonium nitrate 56, boric acid 4, Manganese sulfate 3.2, zinc sulfate heptahydrate 0.8, ammonium molybdate 0.03, copper sulfate heptahydrate 0.09, edetate disodium iron 30, citric acid 15;

[0034] After the nutrient solution is used in hydroponic cultivation of leafy vegetables, the cultivation period of vegetables is shortened by 8 days, the yield is increased by 20%, and the content of nitrate and nitrite is reduced by 60%.

Embodiment 3

[0036] The following substances measured in milligrams were successively fixed in a container filled with 1L deionized water: calcium nitrate tetrahydrate 472, potassium nitrate 212, potassium dihydrogen phosphate 68, magnesium sulfate heptahydrate 492, ammonium nitrate 40, boric acid 2.8, Manganese sulfate 2.4, zinc sulfate heptahydrate 0.2, ammonium molybdate 0.02, copper sulfate heptahydrate 0.08, disodium iron edetate 20, citric acid 10;

[0037] After the nutrient solution is used in hydroponics of leafy vegetables, the cultivation cycle of vegetables is shortened by 5-10 days, the yield is increased by 10%-22%, and the content of nitrate and nitrite is reduced by more than 80% or even several times.

Abstract

The invention discloses a leaf vegetable nutrient solution formula. The leaf vegetable nutrient solution formula is characterized in that leaf vegetable nutrient solution comprises fertilizers and citric acid; the leaf vegetable nutrient solution comprises the following components: major elements of calcium nitrate tetrahydrate 450-500 mg / L, potassium nitrate 180-250 mg / L, monopotassium phosphate 50-80 mg / L, magnesium sulfate heptahydrate 400-620 mg / L and ammonium nitrate 20-70 mg / L; trace elements of boracic acid 1-5 mg / L, manganous sulfate 1-4 mg / L, zinc sulphate 0.1-1 mg / L, ammonium molybdate 0.005-0.05 mg / L, copper sulphate heptahydrate 0.01-1 mg / L and ethylene diamine tetraacetic acid disodium ferric salt 5-40 mg / L; citric acid 3-20 mg / L; and the balance of water. The leaf vegetable nutrient solution formula disclosed by the invention is reasonable in components, good in stability and wide in range of application.

Description

technical field [0001] The invention relates to the technical field of hydroponic leaf vegetable nutrient solution, in particular to a formula of leaf vegetable nutrient solution. Background technique [0002] In daily life, there are many varieties of leafy vegetables, rich in nutrition, and are deeply loved by consumers. Therefore, the cultivation of leafy vegetables is large, takes up a lot of farmland, and consumes a lot of manpower and material resources. The development of soilless cultivation technology for leafy vegetables is a must. inevitable trend. Hydroponics is a new type of soilless cultivation. Hydroponic vegetables means that most of the roots grow in the nutrient solution layer, and only provide water, nutrients, and oxygen through the nutrient solution, so that the plants can grow normally and complete their tasks. The whole life cycle is different from vegetables cultivated under the traditional soil cultivation form, and the formula of hydroponic nutrien...
