With the country’s emphasis on Chinese medicine, hospitals above the county level have resumed traditional Chinese medicine, and Chinese medicine has also entered the ranks of medical insurance and new rural cooperatives to protect sales. This has promoted the use of Chinese herbal medicines, and has also stimulated the enthusiasm of farmers to grow Chinese herbal medicines. Since most farmers do not have the experience of planting Chinese herbal medicines, for this purpose, this newspaper will start the "Agricultural Technology Popularization Seminar-Treating Chinese Medicinal Materials" from this issue. It will provide you with a series of practical new technologies and new experiences in the cultivation of Chinese medicinal herbs. I hope our work can help you to grow Chinese herbal medicines in the future.

Polygonatum is a perennial herb of Liliaceae. Root rhizome medicine, alias: tail ginseng, bell grass, mountain glutinous rice, with kidney nourishing lung, Sheng Jin Yang Wei, lowering blood pressure, strong heart anti-aging, tonic effect. It can treat diabetes tuberculosis, cough, etc. It is a combination of medicine and food. At present, it is loved by people both at home and abroad as a nutritional supplement. Mainly produced in China's northeast, north, Inner Mongolia and other places.

Growth habit

The adaptability of Polygonatum is very strong, like cool and moist, shade environment, cold and avoid direct light and windy, more wild in the wild wetlands, under forests and bushes, with deep soil, well-drained and fertile sand The soil or red loam grows well. Raw and cooked wasteland can be planted on the slopes. Avoid continuous works.

Cultivation Techniques

Soil preparation and soil preparation: choose leeward sunny, loose fertile soil and deep sandy loam. The land where the land is thin at the end of the year and the terrain is low and easy to collect water should not be planted. Combine the land and apply 3,000 kg of farmyard fertilizer per acre, deepen 30 centimeters, make a 1.2 meter wide, 20 centimeters high, and unlimited lengths.

Sowing: At present, it is often used to reproduce with the segment because the growth cycle of the segment is short and the yield is high. Choose no heavy insects, no black spots, no damage, full top buds, and a lot of big roots for planting. Cut the roots with spores into 5 cm sections, and divide the rows by 30 cm. , and then 10 cm away from the planting position of the bud head in one direction, put the seed after the cover of 5 to 6 cm deep, due to the growth of eucalyptus need a certain cover negative. In the first and second years after planting, corn, sorghum, soybeans and other crops can be grown on the side of the plant.

Weeding: after the emergence of the whole period of growth, we must ensure that there is no weed in the field. Weeding can only be carried out when the weeding is done, so as not to cause root rot. Chemical weeding can also be done.

Fertilizing, earth-cultivation: Yuzhu fertilization is best to use the farmyard manure after the autumn stems and leaves will be covered with 5 to 6 centimeters as the best, or in the rain when the urea, phosphate fertilizer spread into the bed or watering. Two years after the growth of Polygonatum odoratum, roots and stems were divided into many subterranean areas, and the roots were disorderly and crisscrossed. Some of them also exposed the ground to cultivate soil in time.

Pest Control

Brown spot disease: brown lesions on affected leaves and brown-yellow mildew on later stages. It mainly occurs in July and August when it is a severe period because the plants grow too densely and the humidity in the field is too large. Control methods: The diseased plants were destroyed in a centralized manner, and were sprayed with zeocin, thiophanate-methyl, tebuterol, etc. in the ninth grade for 5 days and used once every three times.

Rust: The leaves are round or irregular lesions, 1 to 10 mm in diameter, and yellow bad-like granules on the back. In May, it was severe from June to July, and there were more incidences of the rainy season. The method of prevention and treatment can use Baume 0.1~0.2 degrees lime sulfur or dinitrate 300 times, once every 5~7 days, and use 2~3 times.

Insect pests: mainly fleas, with 90% trichlorfon 1000 times Irrigation root.

Harvest processing

In the third year after planting, when the ground part is withered, cut off the stems on the ground, dig up the roots, shake the soil, and dry it for 2~3 days. When it is soft and not easy to break, remove the roots and put it on the wooden board repeatedly to rub it in the sun. Then knead, so repeated 3 or 4 times until no heart is hard, golden color, translucent, feel the time until the juice sticks. Can also be used after steaming and then rubbing. To dry, no impurities, insects, golden color, no mildew, root stout, neat and tidy.
