Snow lotus, mainly distributed in China's Tibet, Sichuan, Gansu, Xinjiang and other places, due to different growth areas, but also points Mt. snow lotus, Tibet snow lotus, Xinjiang snow lotus, jellyfish snow lotus, Maotou snow lotus and other varieties. Among them, there are three kinds of characteristics of Xinjiang Daxue snow lotus plant height 15 cm to 20 cm, flower diameter 10 cm to 20 cm. Flowers yellow-green, brown-purple inflorescence, very beautiful, can be the leader of snow lotus, but slightly toxic. In addition, the height of Qinghai-Tibet Woolhead is 15 cm to 25 cm, flower diameter is 4 cm to 10 cm, the whole plant is densely covered with white cotton wool, and the flowers are white. The inflorescence is hidden in white wool and has high medicinal value. toxic side effect. Due to the extensive medicinal properties of Saussurea, the wild Saussurea has been excavated and sparsely cultivated. At present, Saussurea has been listed as a national first-class protected plant. Therefore, the artificial cultivation of Saussurea has become a top priority. The seed germination temperature requirement of the snowdrop seeds is 15°C～20°C, the saturated soil water content is required to be about 60%, and the moist or sandy soft soil is soft and neutral or slightly acidic, and it takes about 100 days from planting to harvest growth. Saussurea can be cultivated in the seasons that generally satisfy this requirement. In practice, the cultivation of snow lotus should pay attention to such a number of issues: First, prevent seeds from falling. Snow lotus seeds are cone-shaped. When seeds are seeded, they are seeded downwards and they are easy to emerge. However, the seedlings are not strong and the seed tips are not easy to emerge. Therefore, it is best to seed the seed when it is seeded, which will help the seedlings grow robustly. Second, to prevent seedlings rotten species. Early spring is cool, the earth temperature is low, if the soil is too wet, the seeds that don't emerge in 10 days will turn black and rot. Electric heating hotbeds or less watering are commonly used to solve the rotten phenomenon. Third, to prevent seedlings unearthed with caps. Seedlings unearthed with caps directly affect the development of the plant, causing the seed coat shells to emerge when the cotyledons emerge. The reason is that the basin soil is too loose, the soil is too dry, and the cover soil is too thin. The soil should be kept moist and the length of the cover soil should be 0.8 cm to 1 cm. Fourth, prevent blight and damping-off. The blight of snowdrops occurs during the period of 2 to 3 leaves of the seedlings, and the pathogen can infect the dead seedlings. Preventive measures: 1, basin soil to be fully sterilized; 2, the application of rotted fertilizer; 3, pot soil is not easy to wet; 4, found that the diseased plants immediately cleared, and spray fungicide. Fifth, watering should be appropriate. Saussurea is best to use the snow, rainwater, river water and pond water before 10 o'clock in the morning and after 3 o'clock in the afternoon. To use tap water, you must first place it in storage for a day and night so that the chlorine in the water can evaporate. When the water temperature is close to the temperature, it is better to use it again. Six, rational fertilization. The three elements nitrogen, phosphorus and potassium should be reasonably used according to the situation. In general, the spring should be based on nitrogen-based fertilizer to promote the growth of foliage; in summer to apply phosphate fertilizer, promote stem and leaf bud enlargement; autumn in the flower bud stage more potash fertilizer to promote flower Yan and full grain. If taking flowers as the main, the proportion of nitrogen, phosphorus, and potassium is 4:3:2; seeding is the main method, and the application ratio is 2:4:3.
