Cultivation points of Saussurea involucrata

Snow lotus, tibetan called chaguo suba, is a perennial herb of compositae. It is not only rare flowers and herbs, but also world-famous rare Tibetan medicine. The artificial cultivation snow lotus flower market prospect is good, the profit is considerable, now will Jilin Province Da 'an City muskrat farm snow lotus flower base artificial snow lotus flower planting seedling experience introduction to the general friend.

1. Growth habits: Snow lotus grows on the Qinghai-Tibet Plateau and is suitable for various complex climatic environments; it can not wither at 1℃~39℃, grow vigorously at 15℃~25℃, and its roots can safely overwinter at-32℃.

Second, seed selection: to choose full grain, brown black, a large and shiny seed for the seed. Soak in 1∶1500 times solution of strong rooting powder for 1 minute before sowing.

3. Preparation of nutrient soil: Nutrient soil generally includes humus soil, fine sand and decomposed organic fertilizer, which are mixed evenly according to 6:2:2. After disinfection, screen out impurities and hard lumps in the soil, and the pH value of the nutrient soil is 5.5-7.5.

Sowing: The soil temperature of snow lotus seed germination must be controlled between 20℃ and 26℃, which is conducive to seedling emergence. The saturated water content of soil should be about 60%, the seeds should be placed horizontally in the hole, the thickness of soil cover should be the length of seeds or 0.8cm~1cm, and the seedlings should generally emerge in about 8 days.

5. Pay attention to 5 precautions in the process of seedling raising:

1. Prevention of seed inversion: snow lotus seeds are conical, seeds pointed downward, easy to emerge, but seedlings are not strong, seeds pointed upward are not easy to emerge, must be flat.

2. Prevention of rotten seeds: cold weather in early spring, low soil temperature, humidity for 10 days did not emerge, indicating that the seeds have become black rot, so planting must pay attention to the key issues of soil temperature and humidity.

3. Prevention of seedling emergence with cap: seedling emergence with cap directly affects plant development, resulting in cotyledon emergence when the seed shell will be brought out, the reason is too loose soil, soil cover caused by too dry.

4. Prevent hard water irrigation: It is best to irrigate with snow, rain, river water and lake water before 10 a.m. or after 3 p.m. during seedling period. If poured with tap water, it must be stored in a bucket for a day and night to volatilize chlorine in the water, and the water temperature is close to the soil temperature.

5. Prevention of blight and damping-off disease: seedling often due to low temperature and humidity, snow lotus seedlings 25 days or so 2 ~3 leaves, the most prone to blight and damping-off disease. Prevention measures: nutrient soil must be fully sterilized before planting; apply decomposed fertilizer; control soil humidity, remove diseased plants immediately, and spray fungicide "damping-off and withering" to prevent and control.

6. Seedling transplanting: When the seedlings grow to 5cm~6cm, they can be transplanted to flowerpots and fields. It is best to choose to carry out in cloudy days or after rain, which is conducive to seedling survival.
