Storage and fresh-keeping of cut lily flowers
After the cut flowers leave the mother, the life activities such as transpiration and respiration of branches and leaves are still going on, so the water in the body is constantly lost and the organic matter is constantly decomposed and reduced. If you can not replenish water and nutrition in time, slow down the rate of water loss, flowers will wither in a short time, reduce or lose the commercial value of cut flowers. Therefore, the storage and preservation of fresh cut flowers is very important, which generally includes three contents, namely, pretreatment, storage and after-sale bottle insertion, promotion and preservation.
① pretreatment: cut flowers should be pretreated immediately after harvest, including pre-cooling and chemical impregnation.
Pre-cooling: cooling by cold water, cold storage, differential pressure, vacuum cooling and other methods.
Chemical treatment: 20 min 30% sucrose + 1000 ul L silver nitrate solution or 4mmol/L silver thiosulfate solution impregnated the base of the flower stem for 20 minutes.
② storage: cut flowers after pretreatment should be immediately put into cold storage, inserted into cold water that has been pre-cooled to 2Mel 3 ℃, and stored for 48 hours. Low temperature can effectively inhibit the respiration and ethylene production of cut flowers. The storage time of less than 4 hours or more than 48 hours has an effect on the quality of cut flowers. Generally, it can be quickly shipped to the market at low temperature after 4 hours.
The above pretreatment and cold storage can also be carried out at the same time.
③ after-sale bottle insertion, promote opening, fresh-keeping: different flowers, different fresh-keeping solution, suitable for lily fresh-keeping solution has the following two kinds:
3% sucrose solution + 200mg hand L8-hydroxyquinoline
3% sucrose solution + 200mg Band l8-hydroxyquinoline + lmmol/ISTS
The life span of fresh flowers treated with the above-mentioned fresh-keeping solution can be prolonged by more than 2 times. It is worth mentioning that lily pollen has a strong adhesion, falling on the skin or clothing is difficult to remove, so the stamens should be removed before cracking after flowering to prevent pollen contamination of clothing and petals.

Lily cut flower management must plant
① time: according to the required flowering time, in principle, it can be planted at any time of the year. But it's best to avoid the hot summer season. When the air temperature is high, planting should be carried out in the evening, and artificial ventilation, shading and cooling should be carried out to ensure that the soil temperature should not be too high, and the soil temperature should be lower than 20 ℃ at the depth of 5 cm. ② planting method: ditch-on-demand, summer: first ditch and sow ball, then watering and covering soil; winter: first trench, watering and then sowing, covering soil. ③ density: generally 40 units per square meter, depending on variety

Cultivation of Cut Lily Flowers
First, soil preparation selection loose fertile, good drainage loam land. When soil preparation, fully decomposed organic fertilizer shall be applied, 5 square meters per mu, and deep ploughing shall be 30~35 cm. Then make a ridge according to the specification of width 110~120 cm and walkway 50 cm, spread calcium phosphate 10~15 kg, potassium sulfate 4~6 kg and pentachloronitrobenzene 0.8~1.0 kg on every 100 square meters of ridge surface, and dig 20~30 cm again to make the soil loose, broken, flat, soft and fertile. 3 days before sowing, irrigate once. 2. Seed ball treatment seed ball
