Embodiment 1

[0027] Embodiment 1: a kind of Clivia aerosol cultivation method, method step is as follows,

[0028] Step 1, carry out the preparation of nutrient solution mother solution, nutrient solution mother solution is divided into nutrient solution A, nutrient solution B, nutrient solution C, described Ca(NO 3 ) 2 4H 2 O and KNO 3 The composition ratio is 2.34:1, the Ca(NO 3 ) 2 4H 2 The concentration of O is 236mg / L, the KNO 3 The concentration is 101mg / L, and the B component of the nutrient solution is mainly composed of KH 2 PO 4 , (NH 4 ) 2 SO 4, MgSO 4 and K 2 SO 4 Composition, its composition ratio is 1:1.5:2.49:1.17, the KH 2 PO 4 The concentration is 72mg / L, the KNO 3 The concentration is 108mg / L, the MgSO 4 The concentration is 179mg / L, the K 2 SO 4 The concentration is 84mg / L. The C component of the nutrient solution 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 ) 2 MoO 4 ·H 2 The composition of O and E...

Embodiment 2

[0037] Embodiment 2: a kind of Clivia aerosol cultivation method, method step is as follows,

[0038] With the same nutrient solution formula, the added phytohormone concentration is NAA: 10mg / L; IBA: 100mg / L, it can control the relevant resistance physiological indicators of the tested plants such as superoxide dismutase (SOD), hydrogen oxide The enzyme (POD) has a significant improvement effect, and the efficiency is improved by nearly 40% compared with the substrate cultivation method, but the growth indicators such as plant height increment, fresh weight increment, pseudobulb diameter increment, leaf length increment, etc. are not as good as in Example 1.

[0039] Among them: superoxide dismutase (SOD) content is 491.86U·g -1 , the value of aerosol-cultivated young orchids that only use nutrient solution but do not add plant-like hormones in step 6 is 378.01U·g -1 ; And only adopt the nutrient solution but do not add the content value of the substrate cultivation young or...

Embodiment 3

[0040] Embodiment 3: a kind of Clivia aerosol cultivation method, method step is as follows,

[0041] With the same nutrient solution formula, the added phytohormone concentration is NAA: 1mg / L; IBA: 100mg / L, the peak photosynthetic rate, pseudobulb side diameter, leaf growth and new root growth performance are outstanding , but the overall growth of seedling or young orchid is not as good as embodiment 1.

[0042] The peak photosynthetic rate is 6.01μmol·m -2 ·s -1 , and the peak value of young orchids cultivated in the substrate that only uses nutrient solution but does not add plant-like hormones in step 6 is 4.80 μmol·m -2 ·s -1 , the diameter of the side of the pseudobulb is an average increase of 9.65mm, which is 5.84mm higher than that of the aerosol-cultivated young orchids that only use the nutrient solution but do not add the plant hormones in step six, and are higher than the plants that only use the nutrient solution but do not add the plant hormones in step six...

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 an aerosol cultivation method of Clivia. Background technique [0002] Clivia is a representative plant of Amaryllidaceae. Its bright flower color, curly flower shape and full inflorescence are deeply loved by people, and it is a cultivated plant with great commercial value. Because of its gorgeous flower color, upturned flower shape and strong adaptability, Clivia grandiflorum has become an ideal garden plant and potted flower, with high ornamental value in gardening, while Clivia grandiflorum has 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, there are more than 1,200 species of Clivia grandiflora, 17 species of narrow-leaf Clivia, and 12 species of Smiling Clivia registered in the list of Clivia cu...
