Culture method of Gao Xuelun

Gao Xuelun, also known as carnation, is an annual herb of Caryophyllaceae, which has higher ornamental value. China's cities and gardens are cultivated for ornamental use, which can be used as cut flowers or layout flower borders. It is suitable to configure flower diameter, flower border and decorate rock gardens or make ground cover plants, or potted or cut flowers. Let's take a look at the breeding methods of Gao Xuelun.

Growth habits of Gao Xuelun

Gao Xuelun, native to southern Europe, likes warmth and sufficient light, ideal all-day and half-day sunshine, and poor fertility in the shade. It is resistant to cold and drought, likes loose and well drained loam, likes sufficient sunshine and warmth, but avoids high temperature and much humidity. The suitable temperature for growth is about 15 ~ 25 ℃. The cultivated soil quality is the sandy loam with good drainage, ideal all-day and half-day sunshine, and poor growth in the shade.

The breeding method of Gao Xuelun

The optimum temperature for seed germination is 1520 degrees. After sowing, the seeds are covered with fine soil of 0.2 cm and keep humidity. They can germinate after about a week and wait for more than 6 leaves of the seedling to be replanted. It can also be direct seeded, sow the seeds directly in the cultivated land, and then pull out the seedlings. The distance of the flower bed plant is 20: 30 cm, and the potted plant is 4: 5 inch pot.

Culture method of Gao Xuelun

1. Humidity: Gao Snow Wheel likes higher air humidity, which is too low, which will accelerate the withering of a single flower. Also afraid of rain, need to keep the leaves dry at night. The optimum relative humidity of the air is 65-75%.

2. Temperature: Gao Xuelun likes warm climate and avoids extreme heat. It obviously grows poorly when the summer temperature is higher than 34 ℃. Not resistant to frost and cold, enter dormancy or die when the winter temperature is below 4 ℃. The most suitable growth temperature is 15-25 ℃, which is generally sown in autumn and winter to avoid high temperature in summer.

3. Illumination: Gao Xuelun needs sufficient sunlight in spring, summer and autumn. When the temperature is high, if it is maintained in direct sunlight, the leaves will obviously become smaller, the branches will shorten, the foot leaves will yellowing and fall off, and the growth will be very slow or enter a semi-dormant state. After the flowering period is kept indoors for a period of time, it should be moved to a shaded place outside for a period of time, so that the plant can accumulate nutrients and blossom continuously.

4. Fertilizer and water: Gao Xuelun, like other grass flowers, requires more fertilizer and water, but it requires to follow the principle of "light fertilizer applied frequently, less and more times, complete nutrition", and after fertilization, leaves and flowers should be kept dry at night. At the same time, fertilizer and water management should be cycled according to Huabao → clear water → clear water → → clear water →.

5. Pruning: cut off the branches with old and yellow leaves every two months, as long as the temperature is right, it can blossom all the year round. Heart picking is usually carried out twice before flowering to promote the germination of more flowering branches. One to two weeks after potting, or when the seedling is 6-10 cm tall and has more than six leaves, remove the top tip and retain the lower 3-4 leaves to promote branches. The second coring was carried out 3-5 weeks after the first coring or when the lateral branch grew to 6-8 cm long, that is, the top tip of the lateral branch was removed and the 4 leaves under the lateral branch were retained. After two coring, the plant type will be more ideal and the number of flowering will be more.

6. Diseases and insect pests: the common diseases and insect pests of Gao Xuelun include stem rot, rust, aphids, whitefly and so on. The stem rot was sprayed with 50% methyl topiramate wettable powder and the rust was sprayed with 50% verapamil wettable powder 2000 times. Aphids and whiteflies are sprayed with 1000-1500 times of buprofezin or 1.8% avermectin 3000 times.

The four Seasons Management of Gao Xuelun

1. Spring and Autumn: spring and Autumn is the peak growing season for high snow wheels. Outdoor maintenance lasts for 1-4 days, with shorter intervals in sunny days or high temperatures, longer intervals or no watering in rainy days or low temperatures. Keep it indoors for 2-6 days, with shorter intervals during sunny or high temperatures, longer intervals or no watering during rainy or low temperatures.

2. Summer: during the period of high temperature in summer, it often goes into dormancy, does not require much fertilizer and water, and even needs to control fertilizer and water. Outdoor maintenance for 3-5 days, the interval is shorter in sunny or high temperature, longer or unwatered in rainy or low temperature. Keep it indoors for 4-7 days, with shorter intervals during sunny or high temperatures, longer intervals or no watering during rainy or low temperatures. Watering time is arranged as far as possible when the temperature is low in the morning, and keep the leaves dry in the evening. And spray the plants frequently.

3. Winter: Gao Xuelun mainly controls fertilizer and water during the dormant period in winter, the interval period of fertilizer and water management is about 7-10 days, the interval period of sunny or high temperature is shorter, and the interval of rainy or low temperature is longer or no watering. Watering time is arranged as far as possible when the temperature is high at noon on a sunny day.
