Embodiment 1

[0027] Embodiment 1: An aerosol cultivation method of Clivia, the method steps are as follows,

[0028] Step one is to prepare the nutrient solution mother liquid, which is divided into nutrient solution A, nutrient solution B, and nutrient solution C. The Ca(NO 3 ) 2 ·4H 2 O and KNO 3 The component ratio of 2.34:1, the Ca(NO 3 ) 2 ·4H 2 The concentration of O is 236mg / L, the KNO 3 of The concentration is 101mg / L, the nutrient solution B component is mainly composed of KH 2 PO 4 , (NH 4 )2SO 4 , MgSO 4 And K 2 SO 4 Composition, the component ratio is 1:1.5:2.49:1.17, the KH 2 PO 4 The concentration of 72mg / L, the KNO 3 The concentration of 108mg / L, the MgSO 4 The concentration of 179mg / L, the K 2 SO 4 The concentration is 84mg / L. The nutrient solution C component is mainly composed of H 3 BO 4 , MnSO 4 ·4H 2 O, ZnSO 4 ·7H 2 O, CuSO 4 ·5H 2 O, (NH 4 )2MoO 4 ·H 2 O and EDTA-Fe, the composition ratio is 9.92:17.84:6.91:4.94:96, the H 3 BO 4 The concentration is 1.24mg / L, the MnSO 4 ·...

Embodiment 2

[0037] Embodiment 2: An aerosol cultivation method of Clivia, the method steps are as follows,

[0038] With the same nutrient solution formula, the concentration of added phytohormones is NAA: 10mg / L; when IBA: 100mg / L, the relevant physiological indicators of resistance to test plants such as superoxide dismutase (SOD) and hydrogen oxide Enzyme (POD) has a significant improvement effect, which improves the efficiency by nearly 40% compared with the substrate cultivation method. However, the growth indicators such as plant height increase, fresh weight increase, pseudo bulb diameter increase, and leaf length increase are not as good as Example 1.

[0039] Among them: the content of superoxide dismutase (SOD) is 491.86U·g -1 , The value of aerosol cultivated young orchids using only nutrient solution but not adding plant hormones in step 6 is 378.01U·g -1 ; The content of young orchids grown on the substrate using only nutrient solution without adding plant hormones in step 6 is 377...

Embodiment 3

[0040] Embodiment 3: An aerosol cultivation method of Clivia, the method steps are as follows,

[0041] With the same nutrient solution formula, the concentration of added phytohormones is NAA: 1mg / L; when IBA: 100mg / L, the peak photosynthetic rate, the diameter of the pseudobulb side, the increase of leaves and the increase of new roots in a day are outstanding , But the overall growth of seedlings or young orchids is not as good as in Example 1.

[0042] The peak photosynthetic rate is 6.01μmol·m -2 ·S -1 , While the base only uses nutrient solution but does not add the plant hormones in step 6 to cultivate young orchids with a peak value of 4.80μmol·m -2 ·S -1 , The side diameter of the false bulb is 9.65mm on average, which is 5.84mm higher than the aerosol cultivated young orchid that only uses nutrient solution but does not add step 6 plant hormones, which is 5.84mm higher than that only uses nutrient solution but does not add step 6 plants Hormone substrate cultivated young ...

Abstract

The invention discloses an aeroponics method for kaffir lily. The aeroponics method includes the following steps: 1, nutrient solution mother liquor is prepared; 2, refrigeration storage is carried out; 3, the three kinds of nutrition solution mother liquor are mixed according to a corresponding ratio and diluted; 4, the diluted mixed solution is evenly sprayed to roots of the kaffir lily; 5, in the aeroponics cultivation process, similar plant hormones are added; 6, the similar plant hormones are evenly sprayed to the roots or leaves of the kaffir lily; 7, cultivation is carried out till maturity occurs. Compared with the prior art, the aeroponics method has the advantages that as the nutrition solution mother liquor A, the nutrition solution mother liquor B and the nutrition solution mother liquor C are respectively prepared, and extra anti-corrosion bacteriostatic agents are added, effective storage is achieved, and moss in the aeroponics technology is effectively reduced. According to the aeroponics method, as an aeroponics device is used in cooperation, growth of aeroponics seedlings can be accelerated, and nutrition growth of plants can be completed in advance and switched into reproductive growth as soon as possible. Related nursery stock tending work such as rapid propagation and seed selection of the kaffir lily is more facilitated.

Description

Technical field [0001] The invention relates to a cultivation method of Clivia, in particular to a method for aerosol cultivation of Clivia. Background technique [0002] Clivia is a representative plant of the Amaryllidaceae. Its bright flower color, curled flower shape and full inflorescence are deeply loved by people, and it is a cultivated plant with great commercial value. Clivia grandiflora has become an ideal garden plant and potted flower due to its gorgeous flower color, upturned flower shape and strong adaptability. It has high horticultural value, and Clivia lilac is a long flowering period and strong resistance. At present, it is mostly used in fresh cut flowers and garden flower materials. In the past ten years, Clivia grandiflora has participated in most of the breeding work. At present, the Clivia Association has registered more than 1,200 species of Clivia grandiflora, 17 species of Narrow-leaf Clivia, and 12 species of Clivia spp. , 5 species of stout Clivia, 3...
