The latest culture method of six flowers

The six flowers are also known as Chilean lilies, Peruvian lilies and daffodils. They are perennial herbs of the family Amaryllidaceae. They are native to Chile, Peru, Brazil, Argentina and Mexico in Central America. The flowers are like cuckoos and daffodils. The stems and leaves are like lilies, which are of great ornamental value. Let's take a look at the cultivation methods of six flowers.

Ecological habits of six Flowers

Liuhua likes to be dry, afraid of too much Rain Water and high groundwater level, and the soil requires good drainage and aeration, loose and rich in humus, so PH6~PH6.5 is suitable. The suitable temperature for growth is 13C~21 ℃, in which the rhizome of 13C~15 ℃ expands best, when the ground temperature exceeds 20 ℃, the growth is poor, and the optimum temperature for seed germination is 11 ℃. It is more advantageous to germinate if the seeds are placed under the high temperature of 26-31 ℃ for one month before sowing, and then moved to the suitable temperature for germination. Sensitive to sunlight, long-day sunshine can promote flowering and increase the number of flowering, while short-day sunshine can inhibit flowering.

Propagation methods of six-flowered flowers

1. Sowing: the six flowers should be sowed in autumn and winter, and the sowing medium should be disinfected at high temperature with peat soil and sand at the ratio of 1:1, and then installed in the sowing pot. The seeds were sown from mid-October to late November, and the seeds germinated gradually after a natural low temperature of 0.5 ℃ for one month. Then moved to the condition of 15-20 ℃, about 2 weeks, the seed germination rate can reach more than 80%. After germination, the temperature was maintained at 10-20 ℃, and the seeds grew rapidly.

2. Ramet: the six flowers produce many hidden buds on the recumbent rhizome. When the external conditions are suitable, the recumbent rhizome extends in the soil, and some hidden buds germinate until they grow into flower branches. The propagation time of ramets is October. Before planting the plants, the soil should be loose, dry and wet. When ramet, first cut off the upper part of the plant from 30 cm from the ground, then dig up the plant, gently shake the surrounding soil, and the rhizome can be clearly planted on the prepared seedbed.

3. Tissue culture: common terminal buds were used as explants. After regular disinfection and sterilization, they were inoculated on MS medium supplemented with 5 mg / L 6-benzylaminoadenine and 1 mg / L naphthylacetic acid. Adventitious buds were cultured for 2 months, and then transferred to 1/2MS medium with 1 ml naphthalene acetic acid to form tubers.

The Culture method of six Flowers

1. Soil: the fertile sandy loam with good permeability should be selected in the planting site of Liuhua. The thickness of the soil layer is 50 cm and the drainage performance is good. The most suitable soil for the cultivation of six flowers is slightly acidic, so the PH value should be adjusted to about 6.5 according to the physical and chemical properties of the soil.

2. Moisture: Liuhua should have sufficient water supply and high air humidity in the exuberant growing season, and the relative humidity should be controlled at 80-85%. The hot summer is semi-dormant. Attention should be paid to controlling moisture when the temperature is low in winter.

3. Fertilizer: when planting six flowers, combined with the improvement of soil physical and chemical properties and structure, we should apply a large amount of mature organic fertilizer, such as barnyard manure, 30kg to 40kg per square meter, or add appropriate amount of calcium superphosphate as supplement. In the whole growth cycle of the plant, only base fertilizer can not meet the needs of growth and development, so topdressing should be applied in different growth periods.

4. Temperature: proper low temperature (not less than 5 ℃) is given within 1 to 2 months after planting, which is very beneficial to root rejuvenation and plant recovery. The temperature in the growing season is maintained at 8: 15 ℃, and the soil temperature is better kept at about 20 ℃ in summer. The most suitable temperature for flower bud differentiation is 20-22 ℃. In summer, in order to prevent the soil temperature from getting too high, water supply pipes and perlite can be buried underground to achieve the purpose of cooling.

5. Illumination: Liuhua is a strong positive plant, there should be sufficient light in the growing season, and the optimum sunshine hours is 13-14 hours. The natural sunshine time is short in winter and early spring, so supplementary light should be added when cultivated in protected areas. In order to save energy, the supplementary light time should be chosen when the plant has entered the vigorous growth stage. Replenish the light for 4 to 5 hours a day until the natural light reaches about 13 hours.

6. Pruning: 12-15 cm pots are commonly used in six-flowered potted plants. In mid-October, the planting depth is 3-5 cm. After planting, they are watered thoroughly, and leaf buds grow after 30 days. After the beginning of winter, the new buds grow rapidly and the stems and leaves are dense, which affects the growth of flower buds at the base, so it is necessary to sparse leaves, remove small leaf buds and retain sturdy flower buds to achieve the goal of short plants and many flowers.

7. Diseases and insect pests: Liuhua is often harmful to root rot, which can be sprayed with 65% Daimen zinc wettable powder 600 times. The flowers and branches are damaged by aphids, which are sprayed with 2000 dimethoate EC. Liuhua is not sensitive to diseases, on the contrary, aphids, thrips, mites, slugs, caterpillars, pink butterflies and nematodes are very harmful. Pythium is easy to occur when the soil moisture is too high, while the disease caused by Rhizoctonia solani is easy to occur under warm and humid conditions.
