Abstract

The invention relates to a water planting nutrient solution for watercress, which consists of macroelements, microelements and tap water. The macroelements of the nutrient solution comprise carbon, hydrogen, oxygen, sulphur, nitrogen, phosphorus, potassium, calcium and magnesium. The microelements comprise Ferrum, boron, sodium, manganese, chlorine, zinc, copper, silicon, nickel, molybdenum, cobalt and lead. The main components of the water planting nutrient solution comprise calcium nitrate terahydrate, potassium nitrate, ammonium dihydrogen phosphate, ammonium nitrate, heptahydrate, ammonium sulfate, sodium phosphate dibasic dodecahydrate, sodium silicate, magnesium sulfate, ferrous sulfate, magnesium sulfate heptahydrate, potassium dihydrogen phosphate, boric acid, cobalt chloride, copper sulfate pentahydrate, sodium nitrate, nickel chloride, potassium iodide, sodium chloride, ammonium molybdate and lead acetate. The water planting nutrient solution for watercress is high in absorption utilization ratio, and fundamentally overcomes waste caused by excessive or insufficient nutrition as the water planting nutrient solution for watercress is of no pertinence for a long time.

Description

technical field

[0001] The invention belongs to the field of soilless culture nutrient solution, in particular to the technical field of hydroponic nutrient solution of watercress. Background technique

[0002] Hydroponics is the use of modern bioengineering technology, the use of physical, chemical, and biological engineering methods to domesticate ordinary plants and flowers, and improve and summarize them on the basis of scientific practice. It has unique technology, high practicability, and strong operability. The plant production cycle is short and the ornamental value is high. Its core is to fix the plant rhizomes in the planting basket and let the roots hang naturally into the plant nutrient solution. This nutrient solution can replace the natural soil to provide water, nutrients, oxygen, temperature and other growth factors to the plant body, so that the plants can grow normally. and complete its entire life cycle.
