What is Magnolia fragrance? what is the method of planting and breeding orchid incense? what is it? First of all, orchid incense is a kind of plant, and secondly, it is also a brand. If you go to the shopping mall again, pay attention to Yunnan Baiyao toothpaste, there is one kind of Yunnan Baiyao toothpaste. This is what the editor uses now, which is not recommended to everyone. It is really easy to use and can reduce the chance of oral ulcers. This is Ziyun's personal experience.

When it comes to this kind of plant, I can't help but talk so much. Let's share the methods of planting and breeding mint. Magnolia incense is an erect perennial herb of Labiatae. It has strong adaptability to the environment. It can grow in areas below 2000 meters above sea level and likes warm and humid climates. It is a mint variety native to Europe and southwestern Asia. With regard to the specific planting and maintenance of orchid incense, the following four items focus on how to keep orchid incense.

1. Growth environment: the rhizome of Magnolia lanceolata can germinate at 5-6 ℃, and the suitable temperature for plant growth is 20-30 ℃. The rhizome has strong cold tolerance. If the soil maintains a certain humidity, it can still survive the winter in the area of-30 ℃. It is not suitable to be cultivated in the shade. Magnolia incense is not strict on the soil, but the loose, fertile and moist sandy soil or oil sandy soil is better.

Second, cultivation techniques: ph5.5-6.5is suitable for soil requirements of Magnolia incense, and slightly alkaline ones can also be planted with seeds, cuttings, branches and propagation. In production, the method of rhizome propagation is generally adopted. After autumn harvest, the rhizome was left in the soil and dug out before planting. The short, white, sturdy, disease-free and pest-free root bark was selected and cut into small segments with a length of 6-10cm. The planting period was from November to early March, which varied from place to place. The planting land should be deeply ploughed with more bottom fertilizer, and after leveling, ditches should be opened according to row spacing 25cm, ditch depth 6-8cm, seed rhizomes should be scattered into the ditches, followed by soil mulching, rake and compaction, about 1125-1500kg rhizomes should be used per 1hm2.

Third, field management: in the growing period, except for weeding, dredging ditches, preventing stagnant water after rain and timely irrigation, the most important thing is topdressing, usually 4 times, that is, after the seedlings are ready in April, the peak growth period from May to June, after the first harvest in July and the height of 15cm in late August. The fertilizer applied is mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer. Magnolia fragrance is easy to degenerate, so we should pay attention to the selection and retention of species.

Fourth, pest control: the disease of Magnolia lanceolata has rust, and the stagnant water in the field should be eliminated in time, spraying 1000 times of 25% trimethoprim at the initial stage of the disease, or alternately spraying 25% vermicellin and 200 Bordeaux at the beginning of the disease, and stop spraying after 20 days of harvest. Pests include land tigers, bridge-building insects, aphids and red spiders.
