Essentials for artificial cultivation of snowdrops
Snow lotus, known in the Tibetan language, is a perennial herb of Asteraceae. It is not only rare flowers, but also a world-famous rare Tibetan medicine. The artificial cultivation of snow lotus market has a good prospect and a considerable profit. Now we introduce the experience of seedling planting and snowdrop cultivation at Snow Lotus Plant in Daewoo City, Jilin Province, to our friends. First, the growth habits: snow lotus growth in the Qinghai-Tibet Plateau, suitable for a variety of complex climatic environment; in the temperature of 1 °C ~ 39 °C plants do not wither, 15 °C ~ 25 °C strong growth, root -32 °C can safely winter. Second, the seed selection: To select the grain full, brown, black, a large and shiny seeds for the seed. Before sowing, the seeds can be sown by soaking for 1 minute in a 1:1500 solution of strong rooting powder. Third, the preparation of nutritious soil: nutritious soil is generally humus soil, fine sand, decomposed organic fertilizer according to the preparation of 6:2:2 mix. After the disinfection, the impurities and lump in the soil are screened. The pH of the nutrient soil is preferably 5.5-7.5. Fourth, sowing: snow lotus seed germination soil temperature must be controlled between 20 °C ~ 26 °C, is conducive to emergence. The saturated soil moisture content is required to be about 60%. The seed is laid flat in the hole. The thickness of the covering soil is the length of the seed or 0.8 cm to 1 cm. It is usually about 8 days. 5. During the nursery process, pay attention to 5 preventions: 1. Prevent seeds from falling seedlings: Snow lotus seed is in a cone shape. Seed tipped downwards when seeding, easy to emerge, but seedlings are not strong, seed tips are not easy to emerge, and seedlings must be raised. . 2 to prevent bad species: early spring air cool, low soil temperature, humidity, no emergence of 10 days, indicating that the seeds have turned black rot, so the plant must pay attention to the key issues of soil temperature and humidity. 3 to prevent seedlings unearthed cap: seedlings unearthed cap with a direct impact on plant development, resulting in cotyledons unearthed when the seed coat shell out, because the soil is too loose, caused by overlying soil. 4. To prevent pouring hard water: During the seedling period, it is best to use snow water, rainwater, river water, and lake water after the early 10 o'clock or after 3 o'clock. If tap water is used, it must be stored in the barrel for a day and night so that the chlorine in the water can evaporate. The water temperature is also close to the soil temperature. 5 to prevent damping-off and damping-off: often due to low temperature and humidity when raising seedlings, snow lotus seedlings 25 days or so 2 to 3 leaves, the most vulnerable to damping-off and damping-off. Preventive measures: nutrient soil must be fully sterilized before planting; apply rotting fertilizer; control the humidity of the soil and found that the diseased plants are immediately cleared, and spray the fungicide “stand down and stand up†to control. VI. Seedling Transplanting: When the seedlings grow to 5cm to 6cm, they can be transplanted into pots and fields. It is best to choose to do it on cloudy days or after rain, which will help the seedlings to survive.
