The invention relates to a novel water culture nutrient solution for rape. The water culture nutrient solution for the rape contains major elements C, H, O, N, S, P, Ca, Mg and K and trace elements Fe, Mn, B, Zn, Mo and Cu which are required by plant growth, and is divided into a solution A and a solution B, wherein each 1,000ml of solution A comprises the following main components by weight: (1) 336.00mg of copper nitrate tetrahydrate, (2) 404.00mg of potassium nitrate, (3) 157.00mg of ammonium monohydrogen phosphate, (4) 223.00mg of magnesium sulfate heptahydrate, (5) 35.00mg of sodium ferrite and (6) 0.012mg of ammonium molybdate; and each 1,000ml of solution B comprises the following main components by weight: (7) 1,572.00mg of calcium nitrate tetrahydrate, (8) 1,267.00mg of potassium nitrate, (9) 450.00mg of ammonium monohydrogen phosphate, (10) 764.00mg of magnesium sulfate heptahydrate, (11) 53.00mg of ammonium nitrate, (12) 0.18mg of iron sulfate, (13) 3.02g of boric acid, (14) 2.52mg of manganese sulfate heptahydrate, (15) 0.28mg of zinc sulfate heptahydrate and (16) 0.85mg of copper sulfate pentahydrate.
Description
Technical field [0001] The invention relates to a nutrient solution technology specially used for rapeseed hydroponic cultivation, belonging to the field of soilless cultivation. Background technique [0002] Hydroponics is a new type of plant soilless cultivation method, also known as nutrient solution culture. Its core is to fix the plant rhizomes in the planting basket and allow the roots to hang naturally into the plant nutrient solution. This nutrient solution can replace the natural soil The plant body provides growth factors such as water, nutrients, oxygen, temperature, etc., so that the plant can grow normally and complete its 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 hygienic, elegant, and highly ornamental. The advantages of environmental protection and pollutio...
