Description

Calathea orbifolia nutrient fluid
Technical field
The present invention relates to field of plant growing technology; Plant nutrition liquid field particularly.
Background technology
Calathea orbifolia, perennial evergreen herbaceous plant for Marantaceae, Xiao's Maranta, have another name called the roundleaf arrowroot, its Latin formal name used at school is Calathearotundifoliacv.Fasciata, its epitheton " rotundifolia " is " roundleaf " meaning, and kind name " Fasciata " is the meaning of " fasciation ", " having laterally parallel wide colour band ".That is to say that this is that a kind of leaf is rounded, the blade face has laterally Xiao's Maranta foliage plants of parallel wide colour band.The clear kingfisher of, leaf look very large because of its blade, the leaf mellow and full apple that exactly likes are gained the name.It is evergreen draft for many years, root leaf, and the shape of growing thickly, leaf sheath is embraced stem.Plant is comparatively tall and big, can reach 40 centimetres usually, and petiole is shallow brown purple, blade circle or subcircular, and long-width ratio is about 6: 5, and between 20 centimetres to 30 centimetres, it is wavy that leaf margin is usually for diameter, the blunt circle of tip.Blade face pale green or silver gray, pinniform lateral vein have 6 pairs to 10 pairs silver gray streaks, and middle rib also is a silver gray, the general lilac of leaf back pale green.The inflorescence spike.It originates in states such as tropical America Brazil, screen cultivation and formed from roundleaf arrowroot original seed by Europe (Belgium, Holland) people.The property half how wet cloudy environment of happiness high temperature, chilly is cold, avoids high light.18 ℃ to 30 ℃ of growth thermophilics require relative air humidity higher, avoid basin soil and environmental drying.Cultivation should with loose fertile, draining good, be rich in organic acid leaf-humidified soil or peat soil.
The nutritive medium that uses mostly is amount among N, P, K macroelement and Ca, Mg, S, Zn, Cu, Fe, Mn, Mo, the B etc. that contain fixed composition branch, proportioning and consumption, trace element according to the composite use together of different dosage at present.Great deal of experimental proves, make nutritive medium class I liquid I fertilizer bring into play its fertilizer efficiency preferably, must determine kind, proportioning and the consumption of nutritive element according to the feeder capability of the regulation of fertilizer requirement of flowers and soil.Flowers are different with soil type, need to use kind, proportioning and the consumption of nutritive element also different, otherwise are prone to effect instability or negative interaction.
In some nutrition liquid fertilizers, also contain such as tethelin material and Pesticidal and sterilizing agricultural chemicals such as xanthohumic acid, 30 alkanols, quinine, mouth-naphthylacetic acid, Asprin, also be added with Chinese herb medicine in the minority product, though all can obtain effect preferably, its effect is not necessarily because of adding tethelin institute extremely.Because most of tethelin are insoluble in water, in the aqueous solution, very easily decompose and lose activity, and consumption are strict, costs an arm and a leg, and easily causes negative interaction as improper use; The Pesticidal and sterilizing agricultural chemicals all has certain toxicity, and improper use easily causes plant, people and animals' murder by poisoning and environmental pollution.
Calathea orbifolia is seeing the flowers of leaf, serves as main with the promotion leaf growth in planting process.Guaranteeing on the basis that various nutritive elements are supplied in the process of growth, the nitrogenous fertilizer that should suit to supply, with the normal growth of promotion plant, but concrete nutrient solution prescription does not have sophisticated product commercially available at present as yet.
Summary of the invention
The present invention filters out a kind of Calathea orbifolia nutrient fluid prescription for solving the technical problem that exists in the known technology, makes the Calathea orbifolia plant, the plant type height, and the number of blade is many and leaf area is big.
Calathea orbifolia nutrient fluid contains the aqueous solution (mg/L) of following ratio composition: Ca (NO 3) 2478 ~ 649, KNO 3303 ~ 455, KH 2PO 477 ~ 136, MgSO 4148 ~ 257; Trace element (mg/L): Na 2Fe-EDTA20, H 3BO 32.86, MnSO 44H 2O2.13, ZnSO 47H 2O0.22, CuSO 45H 2O0.08, (NH 4) 6Mo 7O 244H 2O0.02.
Advantage and positively effect that the present invention has are: after using nutrient solution prescription of the present invention, and the Calathea orbifolia plant, plant height is brought up to 70.1cm by 40.3cm, and the number of blade has been brought up to 16 by 8, and blade area has 300cm 2Brought up to 688cm 2, improved the quality of Calathea orbifolia greatly.
Embodiment
This test is a cultivation matrix with the import peat composed of rotten mosses, perlite, carries out the soilless culture of Calathea orbifolia, in the cultivation process Calathea roseopicta is watered different nutritive mediums, with observation appropriate nutrition liquid formula.If the nutrient solution prescription of six prescriptions, each prescription is handled arrowroot plant 90 strains of planting.
Prescription: Calathea orbifolia nutrient fluid, contain the aqueous solution (mg/L) of following ratio composition:
A 1：Ca(NO 3) 21180+KNO 3506+K 3PO 4136+MgSO 4693(mg/L)
A 2：Ca(NO 3) 2590+KNO 3253+K 3PO 468+MgSO 4347(mg/L)
A 3：Ca(NO 3) 2945+KNO 3809+(NH 4) 2HPO 4153+MgSO 4493(mg/L)
A 4：Ca(NO 3) 2478+KNO 3455+(NH 4) 2HPO 477+MgSO 4257(mg/L)
A 5：Ca(NO 3) 2840+NH 4NO 3230+KH 2PO 4136+MgSO 4390(mg/L)
A 6：Ca(NO 3) 2649+KNO 3303+KH 2PO 4136+K 2SO 418+MgSO 4148(mg/L)
Trace element (mg/L): Na 2Fe-EDTA20, H 3BO 32.86, MnSO 44H 2O2.13, ZnSO 47H 2O0.22,
CuSO 4·5H 2O0.08，(NH 4) 6Mo 7O 24·4H 2O0.02。
Take by weighing the fertilizer of heterogeneity by prescription dosage, one by one put into the bucket that connects water in advance, a kind of fertilizer of every adding will stir, and can add second kind of fertilizer, successively up to all adding fertilizer, and then be stirred to all fertilizer and get final product after all water-soluble.
The seedling of Calathea orbifolia in the plantation is put into flowerpot on the greenhouse production bed in filling the flowerpot of matrix, and the control greenhouse temperature is 20-28 ℃, relative humidity 80-90%, and intensity of illumination is 15000-20000lux.Plant after the transplanting is in time watered nutritive medium.Growing period is according to the every 7-10 of plant strain growth situation days pouring one time of nutrition liquid, the growing state of routine observation plant.
In order to understand the influence of different nutrient formula, the Calathea orbifolia plant of watering different nutrient formula is carried out the observation of growth potential to the Calathea orbifolia plant strain growth.Indexs such as the plant height of main observation plant, the number of blade, maximum leaf leaf area.
Table 1 different nutrient formula influences Calathea orbifolia growth potential
Prescription Plant height (cm) The number of blade (sheet) Leaf area (cm 2)
A1 42.7 9 300
A2 40.3 8 425
A3 50.6 11 500
A4 69.8 16 652
A5 51.4 10 507
A6 70.1 16 688
As can be seen from Table 1.No matter the Calathea orbifolia of pouring nutrient solution prescription A4, A6 is on plant height, the number of blade and leaf area, all is better than other prescriptions.
