How does loose tail sunflower reproduce?

The main results are as follows: (1) sowing method: most of the seeds used for sowing and reproduction are imported from abroad, and it is difficult to collect mature seeds at home. Potted sowing is commonly used for sowing. The thickness of the covered soil is twice as thick as the seed, and the potted soil is kept moist. When the seedlings are 8-10 cm high, they can be planted separately.

(2) split method: it is generally carried out in combination with changing pots in spring. Select the plants with many tillers, remove part of the old culture soil, and use a sharp knife to divide it into 2 to several clumps from the base joint; each clump should not be too small, there must be 2-3 plants, and retain the root system, otherwise the ramet will grow slowly and affect the ornamental plant. Separate planting after a higher temperature environment, often spray water, in order to restore growth.

What should be paid attention to in breeding of sunflower?

1. Humidity management: loose-tailed sunflower likes a humid climate, requiring the relative temperature of the air in the growing environment to be 70-80%. If the air relative humidity is too low, it will dry up the leaf tip.

2, temperature management: because loose-tailed sunflower is native to the tropics and likes high temperature environment, it has strict requirements on winter temperature. When it is lower than 10 ℃, it grows slowly and begins to enter semi-dormant or dormant state; when it is less than 5 ℃, it can not safely survive the winter; in summer, it can be tolerated when the temperature is above 35 ℃, but its growth will be temporarily hindered. The most suitable growth temperature is 18-30 ℃.

3. Light management: loose-tailed sunflower is not strict with light, likes plenty of sunshine and can withstand half-shade, but grows better when there is enough light.

4. Fertilizer and water management: for potted plants, in addition to adding organic fertilizer to potted plants, proper fertilizer and water management should be carried out in the usual maintenance process.

5. Pruning: winter pruning, when the plant enters a dormant or semi-dormant period in winter, the branches such as thin, disease and insect pests, withered and overdense should be cut off.

6. Change the basin: change the basin every 2-3 years in early spring, and the old plant can change the basin every 3-4 years. After changing the basin, it should be placed in a semi-shady place with high air humidity, and the withered and yellow branches and leaves should be cut off in time.

Loose-tailed sunflower is a kind of cold-resistant and shade-tolerant plant, so when we breed loose-tailed sunflower, we must first arrange the living environment of loose-tailed sunflower, and the indoor temperature should be between 18 and 30 ℃.
