1. Sowing method: most of the seeds used for sowing and reproduction are imported from abroad, so 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 mi 10 cm high, they can be planted separately.

2. The 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 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.

Culture method of loose tail sunflower

Loose-tailed sunflower is also known as yellow coconut and Aoi Murasaki. The color is mainly yellowish green, like warm and humid, semi-overcast ventilated environment, afraid of cold, so cold resistance is weak.

So how to raise sunflower.

Culture method of loose tail sunflower

1. Loose-tailed sunflower is afraid of cold plants, which will freeze to death when the temperature is below 5 degrees Celsius, so breeding loose-tailed sunflower must do its heat preservation measures, and cooling measures should also be done when the temperature is hot in summer.

two。 The soil used for pot cultivation of sunflower should be sandy soil which is acidic and rich in humus, and humus soil can be made of rotten leaves, peat, sand and organic fertilizer.

3. When planting, the root is planted a little deeper, and then the watering content is determined according to the growing period. May to October is a period of vigorous growth, so you should properly water and fertilize, but pay attention to the fact that there is no water in the basin.

4. It is necessary to put sunflower in a ventilated environment, otherwise it is easy to produce red spiders, shell insects and other pests, but also pay attention to regularly spray some pesticides, pesticides can choose 800 times omethoate.

5. To do a good job of daily maintenance, regularly rotate the flowerpot, trim the lower branches and buds, clean up the withered leaves, and arrange the crown for viewing.

The culture method of loose-tailed sunflower likes warmth, cold fear and shade tolerance. The room temperature is above 8 ℃ to survive the winter safely. Below this temperature, the branches and leaves are easy to freeze and scorch, and the serious whole plant will freeze to death. Usually, loose-tailed sunflower can be kept for a long time in a bright and ventilated indoor culture, but avoid outdoor exposure to the scorching sun. In the best growing period of 20-35 ℃, thin fertilizer should be applied 1-2 times a month. Pot soil in winter should be dry, avoid dampness, summer growth period, should be watered to prevent drying. It is necessary to turn the basin and change the soil every 2-3 years. The basin soil can be mixed with 1 beat 3 mountain mud and 2 + 3 river sand, or mixed with half of the river sand and fermented sawdust. Use mud basin or uranium basin to facilitate drainage and ventilation. The cultivated soil must be well drained, and it is best to use the soil with more organic matter. Potted soil can be prepared with humus soil or peat soil plus 1 / 3 river sand or perlite with a small amount of base fertilizer. Should be buried a little deeper when planting, in order to facilitate the new buds to fertilize more, vigorous growth in May-June, once every 1-2 weeks to apply fertilizer and water. Slow-acting compound fertilizer is the best fertilizer. Stop fertilizing after late autumn. Watering should grasp the principle of "dry and wet", pay attention to timely watering during the growing period, keep the basin soil moist, and water twice a day when the growth is exuberant in summer. To control watering after late autumn and on cloudy and rainy days, it is necessary to keep a high air humidity around the plant. In summer, water should often be sprayed to the leaf surface and the ground to increase air humidity. Keep the leaf surface clean in winter, but often spray the least water to the leaf surface or scrub it. The suitable temperature for the growth of loose-tailed sunflower is 25-35 ℃. The cold tolerance is weak, and it is sensitive to low temperature. The overwintering temperature should be above 10 ℃. If it is lower than 5 ℃, the plant is bound to suffer. The main cause of death of northern loose-tailed sunflower in winter and spring is low temperature. Summer should cover 50% of the sun, the most avoid direct sunlight, even if a short period of exposure will cause the leaves scorched yellow, it is difficult to recover. Put it in a bright place indoors, too dark is bad for the growth of sunflower.
