Embodiment Construction

[0009] In this experiment, imported peat and perlite were used as the cultivation substrates, and soilless cultivation of green apple arrowroot was carried out. During the cultivation process, the beautiful arrowroot was irrigated with different nutrient solutions to observe the appropriate nutrient solution formula. Six formulas of nutrient solution were set up, and each formula treated 90 arrowroot plants.

[0010] Recipe: Green apple arrowroot nutrient solution, an aqueous solution containing the following proportions (mg / L):

[0011] A 1 : Ca(NO 3 ) 2 1180+KNO 3 506+K 3 PO 4 136+MgSO 4 693(mg / L)

[0012] A 2 : Ca(NO 3 ) 2 590+KNO 3 253+K 3 PO 4 68+MgSO 4 347(mg / L)

[0013] A 3 : Ca(NO 3 ) 2 945+KNO 3 809+(NH 4 ) 2 HPO 4 153+MgSO 4 493(mg / L)

[0014] A 4 : Ca(NO 3 ) 2 478+KNO 3 455+(NH 4 ) 2 HPO 4 77+MgSO 4 257(mg / L)

[0015] A 5 : Ca(NO 3 ) 2 840+NH 4 NO 3 230+KH 2 PO 4 136+MgSO 4 390(mg / L)

[0016] A 6 : Ca(NO 3 ) 2 649+KNO 3 ...

Abstract

The invention relates to the technical field of plant growing, in particular to the field of plant nutrient fluid. The invention relates to green apple Maranta arundinacea nutrient fluid which comprises water solution (mg / L) containing the following compositions according to proportions: 478 to 649 portions of Ca(NO3)2, 303 to 455 portions of KNO3, 77 to 136 portions of KH2PO4 and148 to 257 portions of MgSO4; and 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. By utilizing the nutrient fluid formulation, the stem length of the a green apple Maranta arundinacea plant is lengthed to 70.1cm from 40.3cm, the number of leaves is increased to 16 leaves from 8 leaves and the leaf area is improved to 688cm<2> from 300cm<2>.

Description

technical field [0001] The present invention relates to the technical field of plant cultivation; in particular, to the field of plant nutrient solution. Background technique [0002] Green apple arrowroot is a perennial evergreen herb of the arrowroot family and the genus of arrowroot, also known as round-leaf arrowroot. Its Latin literature name is Calathearotundifoliacv.Fasciata, and its species epithet "rotundifolia" means "round-leafed" Meaning, the variety name "Fasciata" means "flattened" and "with a wide color band that is horizontal and parallel". That is to say, this is a type of foliage plant of the genus Arrowroot with rounded leaves and laterally parallel wide color bands on the leaf surface. It is named for its large leaves, green leaves, and rounded leaves that resemble apples. It is a perennial evergreen herb with leaves from roots, clumps, and sheaths clasping stems. The plant is relatively tall, usually up to 40 cm, the petiole is light brown-purple, the...
