Carnation, also known as carnation, is one of the major cut flowers in Fuyang. Carnation with its beautiful flowers, elegant, fragrant, long flowering time, easy storage and preservation, widely cultivated throughout our province. Carnation can be divided into the number of flowers on the stem and the size of the flowers: single carnation (standard carnation) is a single flower, and there are several flowers on the main branch of carnation (flower type carnation). (I) Harvesting and post-harvest treatment The cutting of cut carnations can be carried out daily in the summer. In winter, it is generally cut once a week. The time for flower picking can be easily selected in the early morning and early evening. If you need immediate marketing, you can cut the petal when it is clearly visible at 11; if it is shipped out of the market, it can be cut if the petal is less than 5?; if it is stored, it can be sold in the off-season and it can be split into ten on top of the bud. Glyphs, picking when the suit is slightly visible. The flower development on the flower type of carnation is inconsistent. Cut flowers that are not yet available for sale can be removed from the lower 2-3 leaves of the stem. And size classification, bundled into every 20 flowers. Since carnation is sensitive to ethylene, it should be treated with STS (1-2 mmol/L) for half an hour. After STS treatment, it can significantly prolong the flowering time and storage period. (2) Refrigerated flowering carnations, which can not be sold for the time being, can be refrigerated at 3-5°C. The temperature should not be too low, otherwise the petal will be damaged. The flowering buds have a strong antifreezing ability and can be stored at 0-1°C. Long-term storage of carnation, should choose healthy and bud with large flowers. Sprigs should be sprayed with fungicide before or after harvest, then dried, placed in a low-temperature dark room at about 5°C, stems inserted in a mixed solution containing 0.3mmol/LSTS, 10% sucrose, and 55mg/L silver nitrate for 5 hours. About 1 day. (c) The carnation treated with flowering should be sold after the flowers have been opened. Placed at 5-10°C for 12 hours before flowering. The temperature of flowering should be around 25°C, humidity above 90%, and light of 2000 lx for 16 hours per day. The flowering liquid consisted of 7% sucrose, 8-HQC 200 mg/L and 25 mg/L silver nitrate. The stalks of the flowering branches before flowering should be trimmed to about 3 to enhance their ability to absorb flowering liquids. The air in the flowering room must be circulated in order to avoid the harmful effects of ethylene and the growth of mold during flowering. (4) Bottle-spiking solution 1, 5% sucrose + 200 mg/L8-HQS + 20-50 mg/L benzyl adenine. 2. 3% sucrose + 300mg/L8-HQS + 500mg/L than long-term 20mg/L benzyl adenine + 10mg/L. 3, 5 ~ 20mmol / L cis-propenoic acid aqueous solution soak stems for 1 hour, and then transferred to 2% sucrose + 300mg/L8-HQC. 4, 10mmol / LSTS treatment for 10 minutes and then transferred to 5% sucrose + 200mg / L8-HQC + 50mg / L silver acetate (or silver nitrate).
