450,000 species. The types of flowers are as follows:

Annual grass flowers refer to the period from sowing, growth, flowering, fruiting to aging and death, with a life span of one year. Herbal flowers inside. In southern China, most of them are annual grass flowers, and biennial grass flowers are not easy to bloom on flat ground.

3. The cultivation period of annual grass flowers is short, usually blooming within 2-6 months, and will die naturally after blooming and bearing fruit, such as pansies, zinnias, cockscombs, bunch of reds, and peacocks. grass, cosmos, calendula, etc. Annual grasses and flowers are all positive plants, and the cultivation location must have sufficient sunlight to grow and bloom normally. If there is insufficient sunlight, it will easily lead to poor fertility, leggy growth and difficulty in flowering.

4. Although annual flowers have a short lifespan, their blooms are bright and beautiful. They can be used as potted plants, cut flowers or flower beds to beautify. In landscape applications, the types can be changed according to the seasons, bringing people freshness and beauty. , spectacular visual enjoyment. Perennial grass flowers, also known as perennial grass flowers, generally refer to perennial herbaceous flowers among perennial herbaceous plants that bloom beautifully and are mainly used for ornamental flowers. The lifespan of a perennial flower can last for many years. Regardless of whether the aboveground part has bloomed and set fruit, the underground part still maintains life. It can sprout, grow and bloom again in the second year, such as African impatiens, chrysanthemums, gerberas, and ornamental bromeliads. , Shegan, African violet, bird of paradise, firecracker red, etc. ?

5. For ornamental purposes, perennial grass flowers can be used to decorate garden flower beds. They can also be potted or used as cut flowers and flower arrangement materials. Especially among flower arrangement materials, perennial grass flowers are the main source of flower materials. Chrysanthemums, carnations, gypsophila, gypsophila, gerbera, birds of paradise, star flowers, etc. are all important flowers. Perennial flowers include positive plants that like full light, and negative plants that like to grow in diffuse and soft light. Seasonal temperature changes and the length of sunshine have a very obvious impact on the growth and flowering of perennial flowers. They must be managed appropriately to ensure smooth flowering.

6. Vining plants are also called creeping plants or vines. They refer to plants whose stems and branches are easy to elongate and cannot be independent. They must rely on their tendrils or vines to wrap around, climb, or even crawl on the ground. Those that can grow normally include herbaceous vines and woody vines, which are divided into climbing vines, such as melons, caladiums, and vines. They have tendrils or adventitious aerial roots that can wrap around other things to grow. The stems of intertwining vines, such as morning glories, wood roses, multi-flowered black eel vines, honeysuckle, etc., can wrap around other objects.

7. Depending on the shape and location of the hypertrophy, it can be divided into bulbs (such as lilies, amaryllis, daffodils, tennis flowers) and bulbs (such as gladiolus, crocus, freesia) , tubers (such as gloxinia, colocasia, long tube flowers), roots (such as dahlia, gloriosa), rhizomes (such as canna, red ginger flower), etc. Flower bulbs can be divided into temperate or tropical varieties depending on their place of origin. Temperate varieties like cool weather (such as tulips, hyacinths, narcissus, etc.). It is not easy to cultivate flowering bulbs in South China. Bulbs are imported from other places every year and bloom after short-term cultivation. Tropical varieties (such as tuberose, tennis flower, canna) grow well year-round in southern China.

8. The growth cycle of bulb flowers all have the same long-term drought resistance habit - dormancy. The length of the dormant period varies depending on the variety, about 30-90 days. During dormancy, the stems and leaves wither and die, storing a large amount of nutrients in the underground bulbs. However, some varieties only stop growing during the dormant period and there is no obvious death phenomenon (such as Amaryllis). , green onion, purple flowers, etc.). In order to shorten the dormancy period and promote neat flowering in cultivation, low-temperature refrigeration method is often used to break the dormancy of bulbs.

Cultivation method

1. Scorching method: Place the end of the flower branch on the candle flame to burn it, and then immediately put it into alcohol Soak for one minute, then rinse in clean water. Hydrangea, lilac, costus, peony, rose, chrysanthemum, ivory, etc. can all be treated with this method.

2. Soaking method: Immerse the base of the flower branch in boiling water for about ten seconds to block the incision and prevent the juice from flowing out of the flower branch tissue.

3. Deep water first aid method: When the flowers droop, you can cut off a small section of the end of the flower branch, and then put it in a container filled with cold water, leaving only the flower head exposed on the water. After one to two hours, the flower branch will disappear. Will wake up. This method is suitable for both herbs and woody flowers.

4. Use the preservative method: Adding an appropriate amount of flower preservative to the flower arrangement container can extend the flower arrangement time. In addition, using 1/3000 of aspirin aqueous solution or 1/2000 of potassium permanganate aqueous solution to plant irises can extend the flowering period by three to five days. Add appropriate amounts of boric acid, sulfur, carbolic acid, salicylic acid, salt, Vitamins, etc., all have the effect of prolonging the flowering period.

5. Expanded incision method: Generally, the base of the flower branch is cut obliquely; or the base is cut into two to four parts, and small stones are inserted to open the crack; the base can also be hammered to expand the water absorption surface. Among them, the oblique cutting method is the most commonly used, and the latter two are mainly used for woody flowers, such as magnolia, hydrangea, lilac, and wisteria

6. Sterilization method: put alcohol, KMnO4, camphor, boric acid, lemon in the water Acid, salt, alum, etc. can all play a sterilizing role. Only when water does not rot can plants absorb water and stay fresh. Note: It must be prepared into a solution before use. Do not put it directly into water without dissolving it. When using salt, be careful not to make the concentration too high.

7. Nutrition method: After flowers are cut from the mother, they lose their nutritional source. Sugar, beer, aspirin, vitamin C and other nutrients can be added.

8. Spray and injection methods: For many flowers with hollow stems, you can put the flower legs under the faucet and forcefully fill them with water.
