Hence the name of Canna.

I. Culture environment of canna

1, like warm and humid climate, not resistant to frost, suitable temperature 25-30 ℃, like sufficient sunshine fertile land, no dormancy in the origin, annual growth and flowering; strong sex, strong adaptability, almost no choice of soil, moist and fertile loose sandy soil is better, slightly resistant to water and moisture. Afraid of the strong wind. After planting after frost in April-May in spring, the top of the stem formed flower bud after germination, and the floret opened from bottom to top. In the growing season, the pressure of Reagan stem germinated one after another to form a new stem, which blossomed continuously from June to Frosts Descent, and the total flowering period was long. The rhizome overwinters in the south of the Yangtze River, and the north of the Yangtze River must be protected artificially.

2. Canna is not resistant to cold and is afraid of strong wind and frost. It is not strict with the soil, can withstand barren, and grows well in fertile, moist and well-drained soil. After the plant withered in late autumn, cut off the aboveground part, dig out the rhizome, dry it for 2 minutes, bury it in the well-ventilated sand in the greenhouse, do not water it, and keep it for more than 5 ℃ to survive the winter safely.

II. Land planting management of canna

After late autumn, usually from the end of October to the beginning of November, the leaves and flowers begin to turn yellow, then the roots and stems can be dug out, cut off the upper branches and leaves, and placed in a non-freezing room, or buried in a sunny leeward cellar in the courtyard, keeping the temperature at 5: 8 ℃. Check 2-3 times during overwintering to prevent heat or freezing. After no frost in the spring of the following year, the rhizome was divided and planted separately. In the south of the Yangtze River basin, the roots do not need to be dug up in winter, but can be dug out and planted in the following spring when new buds grow. After planting, always keep the soil moist, loosen the soil and weed in time. During the growing period, it can be combined with watering and topdressing for 2 or 3 times to promote robust growth.

III. Pot management of canna

Dwarf varieties should be selected for potted canna. The potted soil should be fertile. Plant 2-3 buds in each pot, pour water after planting, and place them in a place with plenty of light. Topdressing liquid fertilizer before flowering. In the growing period, often keep the basin soil moist, more cake fertilizer and water, can make the plant growth exuberant, luxuriant leaves.

IV. Disease and pest control of canna

Canna has strong adaptability and few diseases and insect pests, and it is very easy to cultivate. the main diseases and insect pests are leaf rollers, ground tigers and so on.

1. Leaf curlers

[insect pest symptoms] from May to August every year, it is easy to cause harm to leaf curlers, mainly to tender leaves and inflorescences, and curl after being killed.

[control method] ① sprayed 800x solution of dichlorvos at 50 latitudes. ② sprays 50% fenitrothion EC 1000 times.

2. Ground tiger

[pest symptoms] planting canna occasionally occurs in tigers.

[control method] ① was captured manually early in the morning. ② perfused the root soil with trichlorfon 600 ~ 800 times solution.

I. the culture method of canna-- morphology

Canna is a relatively low plant with a beautiful shape and a variety of colors. The viewing degree of canna is extremely high, and it is very beautiful surrounded by dense clusters.

Second, the culture method of canna-- habit

Canna likes the high temperature environment, and the humid and hot climate is suitable for growing canna. The temperature of canna should be controlled at about 32 degrees Celsius. Once the ambient temperature is lower than 20 degrees, the flowers will be less likely to bloom. When the temperature is lower than 0 degrees, the problem of freezing injury will occur slowly.

Third, the culture method of canna-sowing

Canna can be collected in winter to ensure that it is most appropriate to sow in spring. Winter seeds need a warm environment to keep warm and prevent frost damage, and it is best to sow seeds and wait for germination at warmer temperatures. The general time of germination is about 25 days.

IV. The culture method of canna-cutting

Canna can also choose cutting methods. Spring and summer is a good time for cutting. Choose strong branches, which are about 10 centimeters long. Plant them in an acid sand bed and wait for 40 to 50 days to slowly take root. Pay attention to insect pests.

Cultivation methods of canna under light

Canna growth should be full-day sunshine, the environment is too dark, lack of light, the flowering period will be delayed. If you put it in a cool place during flowering, you can prolong the flowering period.

Temperature

The suitable growth temperature of canna is 15 ℃-30 ℃. During flowering, placing canna in a place with low temperature and no light can prolong the flowering period, and the ambient temperature should not be lower than 10 ℃.

When the temperature is above 40 ℃, the canna can be moved to a cool and ventilated place. Before and after Frosts Descent, the potted canna can be moved to a temperature of 5-10 ℃ to survive the winter safely.

Watering

During the growing period, canna needs to spray water on its leaves 1-2 times a day to maintain humidity.

Because canna is very fond of fertilizer and moisture resistance, so the basin should be watered thoroughly, and the watering times should be grasped according to the actual situation.

Fertilizer application
