Seed price and planting method of Magnolia lanceolata

Orchid incense, also known as green mint, parsley, parsley, etc., is a perennial erect herb of the mint family Labiatae. In Henan, Hebei, Jiangsu, Zhejiang, Guangdong, Guangxi, Sichuan, Guizhou, Yunnan and other places in China, it is cultivated or wild. Stems and leaves can be distilled and can be used as medicine or edible. Let's take a look at the seed price and planting method of Magnolia.

How much is the seed of Magnolia?

The price of Magnolia seed is about 200 yuan per jin. The twigs and leaves of Magnolia fragrance are often eaten as spices, can also be added to seasonings to increase cooking flavor, individual or mixed with other herbs as refreshing tea. The plant contains aromatic oil, which is used in confectionery, toothpaste and medicine. Leaves, twigs or whole herbs are also used to treat colds and fever, cough, fatigue cough, colds, headache, sore throat, nervous headache, gastrointestinal flatulence, blood stasis pain, eye pain, epistaxis, black therapy, general numbness and infantile sores and furuncle.

The growth habit of Magnolia incense

1. Temperature: when the daily average temperature was higher than 5 ℃ and the soil temperature was more than 2 ℃, the roots, stems, scales and buds began to germinate. The optimum temperature in the growing period was 25: 30 ℃ and could grow normally even when the air temperature was higher than 30: 40 ℃. The underground rhizomes planted before and after the Beginning of Winter could survive the winter safely.

2. Humidity: Magnolia needs more water in the early and middle stages of growth, but it needs sufficient sunshine and dry climate in the bud 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. Illumination: 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 and few branches, thus affecting the yield and quality of essential oil.

4. 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. However, due to the large biomass of the aboveground part, there is a large demand for fertilizer, especially nitrogen fertilizer.

Propagation method of Magnolia incense

1. Sowing and reproduction: because of the great variation of seed reproduction, asexual reproduction is adopted in production.

2. Rhizome propagation: in early spring, the fresh rhizome segments of Magnolia incense were placed in the open planting ditch, compacted with soil and poured through water.

3. Ramet propagation: in early spring, when the new seedling of Magnolia lanceolata grows to about 8 cm, the rhizome is dug up together, and the plant is transplanted.

4. Cuttage propagation: the sturdy aboveground stem was cut into 6 cm long segments from May to June, and cut on the seedbed, rooting and transplanting after survival.

Planting method of Magnolia lanceolata

The main results are as follows: 1. reasonable density: Lanxiang has strong branching ability, many branches and low node positions. the suitable density of the first stubble is about 10 000 plants / mu, the row spacing is about 0.4mm, the plant spacing is about 0.17m, and the suitable density of the second stubble is 4 ~ 45000 plants / mu. Artificial seedling or mechanical thinning must be carried out if it is too dense.

2. Ploughing and weeding: Magnolia incense loosened the soil and weeded for 1 or 2 times before closing. When loosening the soil, it is shallow and loose near the plant, but it can be deeper between the rows, and the soil is hardened and loosened in time after rain. Weeds should be removed manually once before harvest to avoid mixing during harvest and affecting the quality of essential oil.

3. Timely fertilization: in the whole growth period, Lanxiang was topdressing for 1 and 2 times, and 5kg urea was applied per mu when the plant height was 10 cm. The second fertilization can be based on the growth trend. In the first and middle of June, 3 kg phosphate fertilizer and 5 kg urea per mu were applied to promote the increase of oil and yield.

4. timely harvest: the oil content of the stems and leaves of Magnolia incense is the highest in the early flowering season, which is the best harvest time. We should choose the morning of continuous sunny days. The harvest in rainy, windy and weak weather has a great impact on the yield. After harvest, 70% dry on the ground can be distilled and processed.
