White Peony Cultivation Management Technology

The white peony is a perennial herb belonging to the family Ranunculaceae. It is not only a famous ornamental flower, but also a dry root medicine. Native to northern China. Root medicinal. Bitter, sour, cold taste, there is nourishing Rougan, urgency and analgesic function, is one of the necessary raw materials for a variety of proprietary Chinese medicines. First, the morphological characteristics of herbs for the herb. White flowers have single large petals that overlap to form Jinxiu's flower clusters. Root coarse fat, cylindrical or slightly spindle-shaped. Upright stems, alternate leaves, fruiting period from June to August. Second, the biological characteristics of drugs suitable for moderate climate, long-term frost-free areas grow well. But it is both heat-resistant and cold-resistant. Herbal medicine is resistant to drought, fear of moisture, and avoid water accumulation. Rain can cause root rot. Hi sunny. For the cultivation of mountains, sunny slopes should be chosen. There should be no trees and high slopes around, so as not to affect the yield. The soil is sandy loam, sandy loam soil, alluvial loam soil. For fear of continuous cropping, the land where the herbs were planted was replanted at intervals of 2-3 years. Former crops include corn, wheat, beans, and sweet potatoes. Third, cultivation techniques (a) breeding methods 1. Steamed bread breeding At the time of harvest, first cut the roots of peony root from the taro habitat and cut them into processed herbs. The heads of the steamed buns were selected to be thick, full of buds, and free from pests and diseases. According to the size of the buns and the number of shoots, they were naturally cut into 2-4 pieces with a knife, each of which had stout buds. 3 for seedling use. Generally grown peony herb, 1 mu of ground medicine can be planted 2-4 acres. 2. Dividing into roots When harvesting peony, the larger peony root is cut from the place where the taro was placed, leaving the crude root of the penstock, and then cutting it into 2-4 strains according to the natural distribution of its buds and roots. Each plant leaves 1-2 buds and 1-2 roots. The root strips are 18-22 cm long, and long roots and lateral roots are cut off for seedlings. Breeding hoe and hoe root cannot be seeded immediately and must be stored. The method is: Choose a cool, dry and ventilated place or room, spread on the ground moist sand or fine soil 8-10 cm thick, piled on the head or roots. The roots are stored and the buds are facing upwards. The stacking is carried out in the order of 15-20 centimeters thick. After they are set, they are covered with moist sand or mud 12 centimeters thick and surrounded by bricks or other objects. Every 15-20 days should be checked once because sand or mud easily leaks into the pores of the seedlings, leaving the roots uncovered and prone to dry rotting. It should add 10 cm of moist sand or mud to the heap. When it was discovered during storage, it must be turned in time. (b) Planting 1. Planting time should generally be in October, but early planting is preferred. In early September, the temperature can be planted, which is conducive to early rooting and growth; and no later than the first half of November. The next species was too late. The roots and taro that had been stored had been given new roots. When planted, they were easily broken. At the same time, the temperature dropped and the roots were unfavorable, affecting the growth of the second year. 2. Methods Regardless of whether it is flat or sorghum, it is planted at 40-50 cm spacing and 3-40 cm plant spacing. With taro species, open shallow flat points, 2 per hole type of taro, and placed in the hole, 4 cm apart, cut face down, cover the earth 8-10 cm, made a bread-like or ridge-like. Roots and seedlings, open the hole with a hammer or two teeth, the hole is opened into a slope of 35-45 degrees, about 20 meters deep, 2 roots per hole, head south, root north, planted on the slope, buds With the glutinous rice and the glutinous rice, two roots are planted into an external “eight” shape. Roots are planted straight. Roots are fixed with a small amount of soil, and then human manure, cake fat, and superphosphate are applied to the roots and tails. Or ridge shape can be. And cover it with fertilizer, proper soil. (III) Field Management 1. In the first two years after planting, weeds and weeds were planted. Because of the wide spacing of the plants, there were not many seedlings in each hole, which made it easy to breed weeds and hinder the growth of seedlings. After seeding, it is best to spread grass fertilizer on the surface to increase fertility and inhibit the growth of weeds. After planting red teeth the following year, weeding should be carried out immediately. But at this time, the roots are slender and not deeply rooted. Avoid weeding in the loose soil next to the plants, so as not to damage the roots, affect the growth, or even die. In the following April-June, each cultivator weeds 1 time. In the July-August hot season, weeding can be avoided. In winter, dry leaves should be removed and weeding and weeding should be completed. Every time you loosen the soil, you should only lightly smash the roots. After cultivating and weeding 3-4 times a year. 2. Drainage Drugs Xi Gan Xi Gan are afraid of water and generally only irrigated during severe drought. However, in the rainy season, pay attention to drainage, otherwise it is easy to cause rot. 3. Top dressing The first year of dressing does not require top dressing. After that, it should be topdressed once a year. Each time when the seedlings are unearthed, 1,000 kg will be applied per 667 square meters every 2 times before the branches and leaves wither. Spring fertilization is mainly based on quick-release manure 500 kg/667 m2. In March of the fourth year, 1,000 kilograms of human waste, 10 kilograms of ammonium sulfate and 25 kilograms of superphosphate were applied per 667 square meters. In April, phosphate fertilizer was applied again according to the above fertilizer amount. 4. When the buds are budding in mid-late April, the buds will be removed on sunny days in order to facilitate the concentration of nutrients and promote root growth. To harvest the plants, some poor buds should be properly removed, and the rest should be left in order to prepare them. Fourth, the prevention and treatment of leaf mold 1. Disease leaf and green stem disease. Incomplete removal of diseased branches, soil conservation of fertilizer and poor water retention, poor water and fertilizer management, and weak plant growth are more serious. 2. Prevention and treatment techniques Dispose of the diseased plants. In the autumn, the diseased branches are completely cut off, and the fallen leaves are cleaned and burned. Strengthen field management, increase organic fertilizers, promote robust growth of plants, and enhance disease resistance. Chemical control, after the peony germination, sprayed 50% carbendazim 800-1000 times solution from late March to early flowering. Spray once every 10 days or so and spray 3 times. Or spray 50% thiophanate 1000 times, 65% dexamethasone 500 times. 5. Harvest 3-4 years after harvesting and processing. Before the beginning of autumn, dig out the whole root, remove the root, shake off the dirt, scrape the skin off with bamboo, pour into the boiling water pot, and cook until there is no hardship. Remove and dry. After cooking, if the food cannot be dried in time, it should be placed in a ventilated place and should not be stacked. The sun exposure has not dried yet. It can be used for 1-2 hours per day on rainy days. If the peony root is found to be mouldy, it should be quickly washed in clean water, dried with warm fire or sun in the sun. General 4-year-old oyster medicine produces 400-500 kg per 667 square meters, and 3-year-old produces 300-400 kg per 667 square meters. Commercial peony medicines are body weight, thick, firm, non-producing, round, uniform, and powdery. good.
