Problems solved by technology

However, at present, the phenomenon of rotten roots often occurs in the cultivation of vegetables by hydroponics, which reduces the maturity rate of vegetables.
Moreover, most of the current hydroponic nutrient solutions for vegetables are universal, and there is no special nutrient solution for a certain vegetable, which will also reduce the yield to a certain extent.

Abstract

The invention provides a water-culture nutrient solution for green vegetables. Each 1000ml of the water-culture nutrient solution comprises the following effective components by weight: 600mg-800mg of calcium nitrate, 10mg-20mg of monocalcium phosphate, 150mg-210mg of potassium sulfate, 40mg-80mg of monopotassium phosphate, 200mg-300mg of monoammonium phosphate, 400mg-500mg of magnesium sulfate, 300mg-400mg of sodium nitrate, 40mg-100mg of sodium chloride, 10mg-40mg of amino acid and 5mg-25mg of a seaweed extract. The water-culture nutrient solution is capable of meeting requirements of the normal growth and development of the green vegetables on various nutrient contents, low in cost and easy to operate. Furthermore, a root rotting phenomenon is avoided in the water culture process of the green vegetables, and the yield is increased. By adding the seaweed extract, the green vegetables are glossy and relatively high in nutrient content.

Description

technical field [0001] The invention relates to the field of hydroponic nutrient solution, in particular to a vegetable hydroponic nutrient solution. Background technique [0002] Green vegetables are the most commonly eaten vegetables in people's daily life. The reason why they are loved by the public is that green vegetables are the most abundant vegetables in minerals and vitamins. If an adult eats 500 grams of vegetables every day, it can meet the vitamins, carotene, calcium, iron, etc. needed by the human body, provide material conditions to ensure the physiological needs of the body, and help enhance the body's immunity. [0003] At present, the cultivation of green vegetables all adopts the mode of soil cultivation in most areas. Only a few areas have a hydroponic planting method. The hydroponic planting method is cleaner and more nutritious. But at present, the phenomenon of rotten roots often occurs in the cultivation of green vegetables by hydroponics, which redu...
