Nutrient solution for cultivating euphorbia pulcherrima

Abstract

The invention discloses nutrient solution for cultivating euphorbia pulcherrima, which is characterized by consisting of solution A, solution B and solution C together, wherein the solution A selects 0.4g / L Scotts 20-10-20 which comprises the following elements in percentage by weight: 20 percent of N, 10 percent of P, 20 percent of K, 0.1 percent of Mg, 0.1 percent of S, 0.1 percent of Fe, 0.05 percent of Mn, 0.007 percent of Mo, and 0.0157 percent of Zn; the solution B is aqueous solution each liter of which comprises 0.1 gram of KH2PO4 and 0.1 gram of MgSO4; the solution C is aqueous solution each lither of which comprises 0.2 gram of Ca(NO3)2 and 0.2 gram of KNO3; and the optimal formula of the components of the nutrient solution has a volume ratio of the solution A to the solution B to the solution C of 1:1:1 - 1:1.5:2.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to the technical field of poinsettia cultivation nutrient solution. Background technique [0002] Poinsettia (Euphorbia pulcherrima), also known as Christmas tree, orangutan wood, and ivory red, is native to Mexico. Euphorbia is a deciduous erect shrub with alternate single leaves, egg-shaped oval to broad-lanceolate, 10 to 15 cm long, and soft hairs on the back , the leaves on the top of the branches are relatively narrow (also known as bracts), and the leaf margins are blunt, lobed or entire, and the leaves under the stem top inflorescence are narrow, bract-shaped, usually entire, and appear when blooming Red, the terminal cup-shaped inflorescences are arranged in cymes, the involucre is light green, with yellow glands, the whole inflorescence is set off by red bracts, the stems are grayish brown and the tender stems are green, smooth, and contain white latex. The flowe...

Problems solved by technology

Because poinsettia is an introduced flower species, in the industrialized cultivation of poinsettia (potted flower), nutrient solution formula is one of the key technologies, and the research on nutrient solution formula of poinsettia soilless cultivation is still in its infancy in China, and traditional nutrient solution formula is very difficult. It is difficult to meet the growth needs of poinsettia flowers. Therefore, our company has carried out research on the formula of poinsettia nutrient solution, and summed up the formula of nutrient solution of poinsettia suitable for growing in North China.
