People who have a keen observation of life can find that many of today's toothpaste are written on the type of spearmint, which is a kind of mint, which has a different smell from peppermint, and feels more refreshing. So it is widely used in the production of toothpaste by manufacturers, making our toothpaste have a very fresh taste, so how is this fragrant mint grown?

How to plant peppermint seeds

1. Sowing time: planting in autumn and winter in the Yangtze River Basin in southern China, that is, from late October to late November in the north, is suitable for planting in spring, that is, from March to April.

2. Sowing method:

① container: small flowerpots can be used when sowing seeds. You can also use a milk box instead and pierce several small holes with an awl at the bottom of the box.

② soil: plant vanilla seeds are relatively small, and the budding rate is low, so the general sowing soil needs to be loose, breathable, high water holding capacity, and should be fully sterilized. Generally use vermiculite, peat, water moss, perlite, snake sawdust and other mixture. (3) sowing: touch some seeds with your hands and sow them gently on the soil. Then cover the thin soil evenly and pay attention to keeping the soil moisture.

③ watering: water thoroughly after sowing. A fine spray can is used for watering. It is best to use the sitting basin method, that is, use a large basin to hold 3 basins of water, and sit the container in the basin. Let the water seep in through the bottom hole of the container. After sowing, the container should be covered with plastic film, and there are several small holes in the plastic film to breathe. Put the container in the sun and keep the temperature about 20 degrees.

Planting method of Magnolia peppermint

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.

Growth habits of Magnolia mint

1. Wide range of temperature adaptation

When the average temperature of the day was higher than 5 ℃ and the soil temperature was more than 2 ℃, the roots, stems, scales and buds began to germinate, and the optimum temperature in the growth period was 25-30 ℃ and could grow normally even when the air temperature was higher than 30-40 ℃. When planted before and after the Beginning of Winter, the underground rhizome could survive the winter safely.

2. Like to be moist

Magnolia needs more water in the early and middle stages of growth, but it needs sufficient sunshine and dry climate in the budding stage to facilitate the growth of oil gland cells, so it is suitable to grow in the humid climate zone of subtropical monsoon in China.

3. Xi Guang

Magnolia incense is a light-loving plant, and its leaves are not only the organs of photosynthesis, but also the main place to store essential oils. If the planting density is too high and the ventilation and light transmission between plants is poor, it will lead to high branch nodes, few branches and easy shedding of leaves, thus affecting the yield and quality of essential oil.

4. It is suitable for weak acid soil.

The requirement of Magnolia incense on soil is not high, sandy and loose soil is the best, and neutral soil is suitable for pH value. Due to the large biomass of the aboveground part, there is a large demand for fertilizer, especially nitrogen fertilizer.

What is Magnolia incense?

Magnolia incense (scientific name: Mentha spicata Linn.), also known as green mint, spicy mint, Dutch mint, green mint, cilantro, fish parsley. It is an erect perennial herb of the family Labiatae with erect stems and purple or white flowers with a florescence from July to September. The temperature adapts to a wide range, like moisture and light, and is suitable for weak acid soil. The stems and leaves can be distilled to extract Magnolia oil, which can be used as medicine or edible.

The planting method of peppermint seeds is relatively simple, and the viability of orchid incense is also relatively strong. We only need to plant it according to the growth needs of Magnolia fragrance. More observation of its growth state is generally able to raise a more lovely mint.
