The latest culture method of Xiaoli flower

Small lily is an excellent ground cover plant, also known as small chrysanthemum, small flower, etc., for Compositae dahlia perennial bulbous herbs, low plants, long flowering period, representing hope and longing, can be arranged flower beds, flower borders, etc., can also be potted or cut flowers, with high ornamental value, let's take a look at the cultivation method of small lily together!

Growth Habits of Lily

Small sweet flowers like sunshine, suitable for mild climate, suitable temperature for growth of 10~25℃ is good, not only afraid of heat, but also not cold, temperature 0℃ when the root frozen, summer high temperature and rainy areas plant growth stagnation, in a semi-dormant state, not resistant to drought, more afraid of waterlogging, avoid heavy clay, after the root rot. Requirements loose fertile and smooth drainage of sandy loam, low-lying ponding is not suitable for planting.

The breeding method of dahlia

1. Sub-bulb: There are bulbs or corms, tubers, root tuber, etc. in the underground part of small lily. These bulbs or corms, tubers, root tuber, etc. grow small balls around them after one year of underground growth. It is easy to plant these small balls. It is simple to operate and convenient to manage. Just be careful not to plant the ball too deep when planting, usually the thickness of the cover soil should not exceed twice the diameter of the ball.

2, ramets: small lily ramets are best carried out after the soil thaws in early spring. Take out the mother plant from the flowerpot, shake off the excess pot soil, separate the root system as much as possible, cut it into two or more plants with a sharp knife, and each plant divided should have a considerable root system, and trim its leaves appropriately to facilitate survival.

3. Cuttings: After the terminal buds, axillary buds and foot buds of Lilium grandiflorum germinate, they can be rooted by cuttings, and the foot buds grow vigorously and resist diseases and pests. In general, tubers are planted in plain sand pots in early March, kept moist and placed at room temperature above 15℃ for germination. When the foot bud grows two true leaves, it is broken off from the root tuber, inserted into the human element sand to promote the root, sprayed 2 to 3 times a day, and rooted in more than 20 days.

The cultivation method of lily

1, potted: Xiaoli flowerpot soil to garden soil 5 parts, fine sand or slag 3 parts, 2 parts of manure preparation, the bottom of the pot should be added broken tiles for drainage layer. Seedlings with 10 cm pots, slow seedlings after pouring a thin cake fertilizer water, in the seedling height of 20 cm before the bud for 2 times, each time to add new rotten leaf soil, enrich the pot edge.

2, light: small flowers like sunshine, sufficient light is conducive to the growth of small flowers, ensure 6~10 hours of light every day, if long-term shade, insufficient light, poor growth, less flowers, easy to get sick.

3, temperature: small lily likes cold afraid of heat, the temperature in northern China is more suitable, from summer to autumn will bloom, and the Yangtze River basin, summer high temperature, in a semi-dormant state, must be leaf shade, spray cooling.

4, watering: small beautiful flowers luxuriant foliage, water consumption is large, if lack of water to strengthen the light, light leaves scorched, heavy leaves. If there is too much water, the roots are easy to rot, so the pot soil should not be dry and wet, flowering period, summer watering should be more, spring and autumn should be less, rainy days should prevent ponding, the flowerpot pad high, before autumn harvest, less watering or no watering.

5, fertilization: small lily like fertilizer, in addition to the application of sufficient base fertilizer, growth period in addition to midsummer, every 10~15 days apply 10% cake fertilizer water, bud after the application of 1~3% potassium dihydrogen phosphate, promote beautiful color.

6. Pruning: When cultivating a single lily, remove the lateral buds, leave the main branches, control the height of potted plants, remove all axillary buds from the base, pick them as they grow, and leave only one terminal bud. When cultivating four small flowers, when the seedling height is 10~15 cm, 2 nodes are reserved at the base to form 4 lateral branches, each lateral branch only leaves a terminal bud, and 4 flowers can be opened.

7. Pruning: If the lily wants to bloom on National Day, it can be renewed and pruned after flowering in early July. The branches to be cut should be twisted first, leaving about 20 cm high. After wilting, they should be cut again. After shearing, proper water control should be carried out, and the topping should be carried out according to the cultivation requirements. Generally, it should be carefully cultivated for 2 months, and it can bloom on National Day.

Prevention and control of diseases and insect pests of common flowering plants

1. Powdery mildew

[Harm] Powdery mildew damages leaves, pedicels and buds, showing nearly round white powder spots, expanding into white powder mottled, twisted leaves and withering. The pathogen overwinters in the diseased body, spreads by air current, and the disease is serious from September to October.

[Control] At the beginning of the disease, 2% antimycetin 120 aqueous solution can be used 100~200 times or 40% polysulfide colloidal suspension 800 times, sprayed once in 10 days, continuously sprayed 2~3 times.

2. Brown spot disease

[Harm] After the leaves are infected, light yellow dots appear at the beginning, expand and sink, and finally form a nearly circular gray-white central spot with dark brown edges, with ring patterns, 1~5 mm in diameter, and light black mold on the surface. The pathogen overwinters in the remains of diseased leaves, and the disease is serious from June to August.

[Control] 1% Bordeaux mixture or 75% chlorothalonil 600 times can be used for control.

3. Virus disease

[Hazard] Symptoms such as mosaic, chlorosis and dwarfing. The virus is transmitted by cherry mosaic virus, cucumber mosaic virus, tomato spot wilt virus, tobacco streak virus, leafhopper and aphid.

[Control] Non-toxic breeding materials can be used to control virus-transmitting insects.

4, small lily moth

[Harm] The larvae are pale yellow or reddish, occur 2~3 generations a year, and the larvae damage period is 6~8 months.

[Control] 50% fenitrothion can be sprayed 1000 times, such as insect infestation stem, omethoate can be injected 100~200 times.
