The culture method of Xiaoli flower

Xiaoli is an excellent ground cover plant, also known as Xiao Li Chrysanthemum, Xiao Li Hua, etc., for Compositae Dahlia perennial bulb herbs, low plants, long flowering period, representing hope and vision, can be arranged flower beds, flower borders and other places, can also be potted ornamental or cut flowers to use, with a very high ornamental value, let's take a look at the breeding methods of Xiaoli!

The growth habits of Xiaoli

Xiaoli sex like sunshine, appropriate mild climate, growth temperature of 10: 25 ℃ is better, both afraid of heat, and not cold-resistant, temperature 0 ℃ tuber root frozen, summer high temperature and rainy area plant growth stagnation, in semi-dormancy state, not resistant to drought, more afraid of waterlogging, avoid heavy clay, root rot after being soaked. Loose, fertile and well-drained sandy loam is required, and low-lying stagnant water is not suitable for planting.

Propagation methods of Xiaoli Flower

1. Bulbs: there are bulbs or bulbs, tubers and roots in the underground part of Xiaoli. These bulbs or bulbs, tubers and roots grow around them after growing in the ground for a year. Just divide these balls and plant them. Easy to operate and easy to manage. Just be careful not to plant the ball too deep when planting, and usually cover the soil no more than twice the diameter of the ball.

2. Ramet: the ramet of Xiaoli should be carried out after the soil was thawed in early spring. Take the mother plant out of the flowerpot, shake off the excess potted soil, separate the root system as much as possible, and cut it into two or more plants with a sharp knife, each with a considerable root system. and its leaves are properly trimmed to facilitate survival.

3. Cuttage: the terminal bud, axillary bud and foot bud of Xiaoli flower can be cut to root after germination, and the foot bud seedling is strong in resistance to diseases and insect pests. Generally, the tubers were planted in a plain sand basin in the first ten days of March, kept moist, and germinated at room temperature above 15 ℃. When the foot bud grows 2 true leaves, break it from the root and insert it into the vegetarian sand to promote the root. Spray water 2 or 3 times a day and take root in more than 20 days.

The culture method of Xiaoli flower

1. Pot: Xiaoli flowerpot soil is made of 5 parts of garden soil, 3 parts of fine sand or slag and 2 parts of barnyard manure. Broken tiles should be added to the bottom of the pot as drainage layer. Seedlings with 10 cm basin, slow seedling after watering once thin cake fertilizer water, before the seedling height of 20 cm before budding, change the basin twice, each time to add new rotten leaf soil to enrich the edge of the basin.

2. Illumination: Xiaoli is fond of sunlight, sufficient light is beneficial to the growth of Xiaoli, ensuring 6-10 hours of light every day, if long-term shade, lack of light, then poor growth, few flowers, easy to get sick.

Temperature: Xiaoli likes cold and heat, the temperature in northern China is more suitable, from the Summer Solstice autumn will blossom, while the Yangtze River basin, summer high temperature, in a semi-dormant state, must be foliage shade, spray cooling.

4. Watering: Xiaoli flowers have luxuriant branches and large water consumption. If there is a lack of water to strengthen the light, the leaves will be scorched at the light, and the leaves will be withered if they are heavy. If there is too much water, the root is easy to rot, so the pot soil should be neither dry nor wet, flowering period, summer watering should be more, spring and autumn should be less, rainy days should prevent stagnant water, put the flowerpot high, before the autumn harvest, less or no watering.

5. Fertilization: Xiaoli likes fertilizer. In addition to applying sufficient basic fertilizer, 10% cake fertilizer and water are applied every 10 to 15 days during the growing period except in the middle of summer. After budding, 1% potassium dihydrogen phosphate is applied to promote the flower color.

6. Pruning: when cultivating only Xiaoli flowers, remove the lateral buds and leave the main branches. the potted plants should control the height, remove all the axillary buds from the base, pick along with the growth, and leave only one flower in the terminal bud. When cultivating four Xiaoli flowers, when the seedling height is 10cm to 15cm, two segments are left at the base to form four lateral branches, each of which has only one terminal bud and can produce four flowers.

7. Pruning: if Xiaoli wants to blossom on National Day, it can be renewed and pruned after blooming in early July, twisting the branches to be cut first, leaving a height of about 20cm, then cutting after wilting, properly controlling water after cutting, and picking out the core according to the requirements of culture, generally carefully cultivated for 2 months, which can blossom on National Day.

Pest control of Xiaoli flower

1. Powdery mildew

Powdery mildew is harmful to leaves, pedicels and buds, which appears nearly round white powder layer spots, expands into powdery powder layer mottled, leaves twisted and withered. The pathogen spent the winter in the diseased body and spread by air, and the disease was serious from September to October.

[prevention and treatment] at the initial stage of the disease, 2% antimycin 120 aqueous agent 100 times 200 times or 40% polysulfide suspension 800 times, sprayed once in 10 days, 2 times in succession.

2. Brown spot

[harm] after the leaves were infected, the yellowish dots first appeared, expanded and sunken, and finally formed a near-round central gray-white, edge dark brown white disease spot, with a wheel pattern, 1mm in diameter, and a light black mildew on the surface. The pathogen wintered in the remnants of diseased leaves, and the disease was serious from June to August.

[control] it can be controlled 600 times with 1% Bordeaux solution or 75% chlorothalonil.

3. Virus disease

[harm] showing symptoms such as mosaic, chlorosis, dwarfing and so on. The viruses are Xiaoli mosaic virus, cucumber mosaic virus, tomato spot wilt virus, tobacco line virus, leafhopper and aphids.

[prevention and control] non-toxic breeding materials can be selected to control virus-transmitting insects.

4. Plutella xylostella

[harm] the larvae are yellowish or reddish, with 2 or 3 generations a year, and the larvae are harmful from June to August.

[prevention and control] 50% fenitrothion can be sprayed 1000 times, such as moth-eaten stem, 100 times 200 times omethoate can be injected.
