Introduction
ã€Biological characteristics】 Also known as purse flower, it is a perennial herbal flower of Scrophulariaceae, often cultivated for one year. Plant height 20 to 30 cm, hairy stems and leaves. Leaves opposite, ovate or ovate-elliptic. The corolla has two lips, resembling two cysts, with a small upper lip, a forward extension, and a downwardly curved lower lip. It swells like a purse, with style between the upper and lower lips, two stamens, and capsules. Flowering around the Spring Festival.
ã€Purpose】 Po Puhua originating in South American countries, sexual warm winter warm summer cool and well-ventilated environment, both afraid of hot and cold and not tolerant to cold, the growth temperature is 13 ~ 25 °C, the minimum requirement is 5 °C or more. Like the sandy loam rich in humus, it is appropriate to be neutral or slightly acidic. It is required that the soil is moist but not watery and it needs high air humidity. Pu flower is a long day of flowers, requires sufficient light, but avoid direct sunlight in summer. Types and varieties: There are about 300 species of genus Perilla, which is the representative species of horticulture and is the general name for potted hybrids. There are three main types: 1 large flower system: 3 to 4 flower diameters and 4 to 6 cm flower stems. 2 spend more than dwarf lines: 2 to 3 flower diameters, plants low, with a few flowers. 3 Flowers and dwarfs: Between the above two, the flower diameter is slightly smaller than the large flower system, and there are many flowers.
[Propagation] Many seeding methods are used, and cuttings and tissue culture methods can also be used. Seeding method: In late August and early September, when the weather is cool, if the temperature is too high, the seedlings are susceptible to rot. If the seeds are sown too early, the growth period of the plants is short. The sowing soil is mixed with peat soil and fine sand in a ratio of 1:2. Because the seeds are small and easy to spread, they can be covered with a thin layer of fine sand after sowing. The sowing container is placed in the semi-shade, and the germination temperature is 15～ 21 °C, about one week or so can emerge, after the emergence of timely removal of newspapers, placed in a ventilated place and gradually see the light, otherwise it is prone to damping off. Seedlings grow to 2 true leaves when the seedlings. The stem tips were used as explants in tissue culture. The medium for induction and differentiation was MS+BA2 mg/L+NAA0.02 mg/L, and the rooting medium was 1/2 MS+ABT 1.5 mg/L.
[Cultivation] Seedlings growing from 2 true leaves can be on the 128-reservoir plates until they grow to 8-10 leaves and then moved into 15 cm pots. The potted soils are easy to use with humus-rich fertile soil. base fertilizer. Generally every 1 to 2 weeks after the fertilization once, you can apply thin cake fertilizer water, can also be interspersed with compound fertilizer, flowering, pay attention to increase the application of superphosphate, with 0.5% to 1% is appropriate. Pay attention to indoor ventilation, the substrate can not be too wet, otherwise it will easily cause the bottom leaf to rot. The temperature is maintained at 13-15°C and grows well, and should cover the strong light before and after noon. Winter is easy to cultivate in low-temperature greenhouses, the temperature should not be too high. The dry and wet cycle of the substrate should be short and dry and over-wet should not be conducive to growth. The leaves of the balsam furrow have hairiness. Therefore, when watering and fertilizing, do not put the fertilizer and water on the leaves so as to avoid causing rot and not to spend. Water spray. In addition, water should often be sprayed on the ground to increase the air humidity. After flowering, seeds mature gradually. To obtain better seeds, artificial pollination must be carried out. During the seed maturation process, appropriate shades should be taken to strengthen ventilation and watering, so as to avoid wilting effects and fruiting, and seeds must be harvested immediately after they mature in May and June. Otherwise, the capsule cracks and the seed loses. Seed China reminds you that Pupa flower is a long-day plant, if necessary, it can be flowered earlier by adding light. For example, if you increase the light every day for 3 to 4 hours from mid-November, you can flower in late December. In order to prolong the flowering period, the temperature can be maintained at about 8°C.
ã€Pests and Diseases】 Bumpling disease: The seedling stage is highly susceptible to the disease. After the onset of the disease, a water-stained lesion appears at the base of the stem. The diseased part becomes yellow-brown and the depression collapses into a line. The disease develops rapidly. A large number of seedlings fell to death, especially when the humidity was too high. Locusts and red spiders: They are common pests during growth and should be sprayed with dimethoate or other insecticides.
