Embodiment 1

[0012] A nutrient solution for soilless cultivation, made from the following raw materials: 4 parts of potassium nitrate, 2 parts of calcium nitrate, 1 part of potassium sulfate, 2 parts of ammonium dihydrogen sulfate, 2 parts of superphosphate, 3 parts of urea, ethylenediaminetetra 1.5 parts of iron acetate, 0.02 parts of manganese sulfate, 0.01 parts of zinc sulfate, 0.001 parts of borax, 0.05 parts of ammonium molybdate, 6000 parts of water, appropriate amount of citric acid.

[0013] The method for preparing the nutrient solution is as follows: mix the components except citric acid according to the ratio, mix well and add an appropriate amount of citric acid to make the pH value of the nutrient solution between 6.5 and 7.5.

Embodiment 2

[0015] A nutrient solution for soilless cultivation, made from the following raw materials: 5 parts of potassium nitrate, 4 parts of calcium nitrate, 2 parts of potassium sulfate, 3 parts of ammonium dihydrogen sulfate, 3 parts of superphosphate, 4 parts of urea, ethylenediaminetetra 2 parts of iron acetate, 0.03 part of manganese sulfate, 0.02 part of zinc sulfate, 0.002 part of borax, 0.1 part of ammonium molybdate, 7000 parts of water, appropriate amount of citric acid.

[0016] The method for preparing the nutrient solution is as follows: mix the components except citric acid according to the ratio, mix well and add an appropriate amount of citric acid to make the pH value of the nutrient solution between 6.5 and 7.5.

Embodiment 3

[0018] A nutrient solution for soilless cultivation, made from the following raw materials: 6 parts of potassium nitrate, 7 parts of calcium nitrate, 3 parts of potassium sulfate, 5 parts of ammonium dihydrogen sulfate, 4 parts of superphosphate, 5 parts of urea, ethylenediaminetetra 2.5 parts of iron acetate, 0.03 parts of manganese sulfate, 0.02 parts of zinc sulfate, 0.003 parts of borax, 0.15 parts of ammonium molybdate, 8000 parts of water, appropriate amount of citric acid.

[0019] The method for preparing the nutrient solution is as follows: mix the components except citric acid according to the ratio, mix well and add an appropriate amount of citric acid to make the pH value of the nutrient solution between 6.5 and 7.5.

Abstract

The invention discloses a soilless culture nutrient solution. The soilless culture nutrient solution is prepared from the following raw materials: potassium nitrate, calcium nitrate, potassium sulfate, ammonium dihydrogen sulfate, manganese sulfate, zinc sulfate, calcium superphosphate, urea, borax, iron ethylenediamine tetraacetic acid, ammonium molybdate, water and citric acid. The soilless culture nutrient solution has the beneficial effects that the soilless culture nutrient solution is reasonable in ingredient collocation, simple in blending, wide in range of application and sufficient in nutrition and can be used for increasing the yield of crops very well.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a nutrient solution for soilless cultivation. Background technique [0002] Soilless cultivation refers to the method of cultivating crops with nutrient solution or solid substrate plus nutrient solution without soil. It has changed the planting habit of agricultural production that has relied on soil since ancient times, and pushed agricultural production to a new stage of industrial production and commercial production. . Its core is not to use natural soil. Plants are produced in cultivation devices filled with nutrient solutions or grown in solid substrates containing organic fertilizers or filled with nutrient solutions. This artificially created plant root environment can not only meet the needs of plants for mineral nutrition. , moisture and air conditions, and can be artificially controlled and adjusted. There are many kinds of soilless culture ...
