Embodiment 1
[0098] Embodiment 1, pre-harvest freshness of Chrysanthemum
[0099] The cut flowers of Chrysanthemum were used as experimental materials, and the cuttings were used for colonization, followed by conventional planting and cultivation management.
[0100] Chrysanthemum pre-harvest preservative is prepared from sucrose, citric acid, potassium nitrate, ammonium nitrate, magnesium sulfate, and calcium chloride.
[0101] The concentration of each component in the pre-harvest fresh-keeping solution of Xiaochrysanthemum can be A3 or A4:
[0102] A3, sucrose 20g / L; citric acid 0.5g / L; potassium nitrate 2g / L; ammonium nitrate 1.5g / L; magnesium sulfate 0.5g / L; calcium chloride 0.5g / L;
[0103]A4, sucrose 10g / L; citric acid 0.25g / L; potassium nitrate 1g / L; ammonium nitrate 0.75g / L; magnesium sulfate 0.25g / L; calcium chloride 0.25g / L.
[0104] The specific experimental concentration ratio is shown in Table 1, wherein CK is the data of clear water (distilled water) of the blank control g...
Embodiment 2
[0121] Embodiment 2, small chrysanthemum pretreatment preservation
[0122] The postharvest pretreatment liquid of Chrysanthemum is prepared from sucrose, 8-hydroxyquinoline, citric acid, calcium chloride, Tween-20, 6-benzylaminoadenine, and 2,4-dichlorophenoxyacetic acid. The specific concentration setting is shown in Table 2, wherein CK is the data of the control group clear water (distilled water).
[0123] Table 2 Concentration settings of postharvest pretreatment solution of control group and different Chrysanthemum chrysanthemum
[0124]
[0125] Among them, individual drug preparation methods:
[0126] 1. 6-benzylaminoadenine: Add a small amount of 40% NaOH solution dropwise into 6-benzylaminoadenine to dissolve it completely, and gradually add distilled water at room temperature to dilute.
[0127] 2. 2,4-Dichlorophenoxyacetic acid: Add a small amount of absolute ethanol dropwise into 2,4-dichlorophenoxyacetic acid, stir while dripping to dissolve completely, then...
Embodiment 3
[0136] Embodiment 3, small chrysanthemum vase preservation
[0137] The small chrysanthemum vase preservative is prepared from sucrose, Tween-20, 8-hydroxyquinoline, citric acid and calcium chloride.
[0138] Specifically, as shown in Table 3, the data C1, C3, C4 and CK of the different experimental groups of the chrysanthemum vase fresh-keeping liquid are the data of the blank control group of clear water (distilled water), and the data of the control group C2 and C5.
[0139] Table 3 Different concentration settings and control group data of chrysanthemum bottle cutting fresh-keeping solution
[0140]
[0141] Harvesting and processing: select plants with fresh leaves, no damage to flower buds, and no damage to flower branches. Process the flower branches into a length of 65 cm, remove the lower 25 cm leaves, and make 10 branches into a handful.
[0142] Water absorption: Put the cut chrysanthemums into water tanks, add 2.5L of water to each bucket, and keep the water fo...
