Embodiment Construction

[0009] In this experiment, imported peat and perlite were used as cultivation substrates to carry out soilless cultivation of Arrowroot. During the cultivation process, Arrowroot was irrigated with different nutrient solutions to observe the appropriate nutrient solution formula. Set the nutrient solution formula of six formulas, each formula handles planting 90 arrowroot plants.

[0010] Formula: beautiful arrowroot nutrient solution, an aqueous solution containing the following proportions (mg / L):

[0011] A: Ca(NO 3 ) 2 590+KNO 3 253+KH 2 PO 4 68+MgSO 4 347(mg / L)

[0012] B: Ca(NO 3 ) 2 945+KNO 3 809+KH 2 PO 4 153+MgSO 4 493(mg / L)

[0013] C: Ca(NO 3 ) 2 1180+KNO 3 506+K 3 PO 4 136+MgSO 4 693(mg / L)

[0014] D: KNO 3 700+Ca(NO 3 ) 2 200+Ca 3 (PO 4 ) 2 1090+MgSO 4 450+(NH 4 ) 2 SO 4 156(mg / L)

[0015] E: Ca(NO 3 ) 2 250+KNO 3 700+Ca(H 2 PO 4 ) 2 350+(NH 4 ) 2 SO 4 520+MgSO 4 350(mg / L)

[0016] Trace elements (mg / L): Na 2 Fe-E...

Abstract

The invention relates to the field of plant nutrient fluid, in particularly to beautiful Maranta arundinacea nutrient fluid which comprises water solution (mg / L) containing the following compositions according proportions: 590 to 945 portions of Ca(NO3)2, 253 to 809 portions of KNO3, 68 to 153 portions of KH2PO4 and 347 to 493 portions of MgSO4; and comprises microelements (mg / L): Na2Fe-EDTA20, 2.86 portions of H3BO3, 2.13 portions of MnSO4 question mark 4H2O, 0.22 portion of ZnSO4 question mark 7H2O, 0.08 portion of CuSO4 question mark 5H2O and 0.02 portion of (NH4)6Mo7O24 question mark 4H2O. After using the nutrient fluid formulation, the stem length of a beautiful Maranta arundinacea plant is lengthened to 42.7cm from 20.1cm, the number of leaves is increased to 16 leaves from 8 leaves, and the leaf area is improved to 300cm<2> from 150cm<2>, thus greatly improving the quality.

Description

technical field [0001] The invention relates to the technical field of plant cultivation; especially the field of plant nutrient solution. Background technique [0002] Beautiful arrowroot (Calathea roseopicta), also known as leaf-decorated arrowroot, is a perennial herbaceous flower of the arrowroot family Arathea genus. The leaves of the beautiful arrowroot are oval to lanceolate, with a length of 20cm and a width of 8cm. There are many pairs of milky white spots between the lateral veins. The young plant is pink, and the underside of the leaves is purple. During the growth of beautiful arrowroot, it likes high temperature, humidity and semi-shade environmental conditions, so during the cultivation process, it is necessary to maintain sufficient water in the cultivation medium, but avoid too much water in the cultivation medium. During the cultivation process in summer, strong sunlight should be avoided, and water should be sprayed on the leaves frequently. The temperatu...
