How to extend the flowering period
After cutting the flower, it is necessary to extend the viewing period. The first is to maintain the balance of water in the leaves and the second is to sterilize and protect. The main methods are as follows: 1. Cut the flower splicing splicing to cut the squid when it is ready to be placed, pruning after flowering, otherwise the flower withered quickly and the flowering period is short. The cut flowers must be cut in the morning, inserted into the water while being cut, placed in a cool place, and protected from sun exposure to reduce transpiration and water loss. Second, cutting treatment, improve the water absorption function of the lignification or thicker branches, such as plum, waxy, magnolia, crape myrtle, etc., in the base of the lower part of the branches 3 cm, with a hammer to break or crack, can expand the water absorption surface. Lagerstroemia, woody and other hard and brittle squid will break the base end, maintain more and complete transmission of tissue, can increase the amount of water absorption. Lotus, water lily and other aquatic cut flowers, thick stems in the tube, easy to enter the air after shearing, affecting the water absorption of flower arrangements. The flower branches can be inverted before the flower arrangement, and the water is poured from the base end of the incision, which can eliminate the air, improve its water absorption function, and prolong the flowering period. For multi-branch milky, syrupy flower branches, such as poinsettia, peach, plum etc. Burning the base end incision with a candle or an alcohol lamp can prevent the outflow of juice and incision, infiltration, and increase the water absorption function. Dipping the base of herbaceous cut flowers such as gladiolus, tuberose, etc. into hot water at 80°C (adding a small amount of salt or alum) for 2 to 3 minutes, and then inserting the bottle, it also has a good effect. Third, the application of preservatives with peppermint oil, alcohol, acetic acid, dilute hydrochloric acid, etc., coated base incision can be preserved. The use of 0.03% aspirin or 0.025% potassium permanganate solution as a flower culture medium for Cymbidium may extend the flowering period by 3 to 5 days. Adding appropriate amounts of sucrose, vitamin B12, boric acid, sulfur, salt, and lithospermic acid in the flower water can both sterilize and add nutrients, increase water absorption, and inhibit flower senescence. According to the ratio of 98 ml of sterile water, 2 ml of anhydrous alcohol, and 2 grams of sucrose, the fresh-keeping liquid for flower arranging is prepared, and a small amount of 8-hydroxyquinoline citric acid is used as a bactericidal agent for flower arranging. It is changed every 2 to 4 days. , can extend the shelf life of 2 to 2.5 times.
