Shouwu, also known as fleece-flower root, Chishaowu, is the root of the Polygonum multiflorum that is a perennial herb. Medicinal parts are its roots and canes (called vines at night). Root block has liver and kidney, benefits essence, UFA and other effects. Students pass through the stool and resolve sores. Stems of vines have nourishing the nerves, antiperspirants, rheumatism, and topical antipruritic effects. In recent years, the market demand for Shouwu has increased year by year, but the resources of wild Shouwu are becoming scarce. Therefore, the prospect of the home grown Shouwu market is broad, and the main points of its high-yield cultivation techniques are described below. Adapting to climate and soil 1. Land selection: Shouwu prefers a warm and humid climate. In a warm climate, with plenty of sunshine, the land is moist and fertile, and a well-drained semi-mud semi-sand is most suitable for planting. The sticky, coarse sand, hard and thin lands should not be planted. 2. Soil preparation: In the selected land, deep plowing 50cm, drying land, applying plant ash, soil miscellaneous fertilizer as base fertilizer. Then from the cocoon, cockroach height 27cm, width 67 ~ 83cm, generally planted double rows, row spacing 2727cm, or planted using five sides, spacing 27cm. 3. Characteristics of Shouwu: When the first species is planted, it is afraid of heat, fear of exposure, and shade. The early growth is slower and the later growth is faster. It is best to interplant with melons, vegetables, and beans. You can use shades of melons, vegetables, and beans to cover the shade. After the melons, vegetables, and beans are harvested, some short-term raw vegetables or medicinal herbs can be grown, and then Shouwu has arrived. Growing vigorously on bamboo fence. Cultivation methods 1. Planting season: It is most suitable to be planted in the new calendar year from the beginning of March to May. The climate in this time is neither too cold nor too hot. There is plenty of rain and the survival rate after planting is high. It can also be planted from June to July, but the climate is hot and the sun is fierce. If there is no proper shade after planting, the survival rate is extremely low. 2. Selection of seedlings: cane seedlings and cane straight and head method. All localities can be selected according to local conditions and planting habits, but the selection is the key link in the level of yield. It is best to choose the purple and purple vines as the best species, and the old and tender vines should not be planted. (1) Small cane seedling raising method: After selecting a good vine, select a well-drained place for the seedbed, and raise seedlings between the cold and convulsions. Before growing seedlings, three sections of buds are cut into sections of about 13-20 cm in length, inserted at 3.5 to 7 cm from the planter to the seedbed, and buried in two sections. The soil is exposed on the ground and covered with straw, and the water is poured once every two days. Keep the seedbed moist but not too wet. Wet vines perish and die. Ten to fifteen days can grow new root buds, rooting can be transplanted in about a month. (2) Cane straight-in method: Select a good type of rattan and cut the width of the plant surface and insert the cane directly at an angle of 45 degrees. After the planting, insert and then slightly compact the plant. Cover the plant with a thin layer of straw and keep the water moist. In general, 50cm seedlings are planted in one row, 84cm seedlings are planted in 2 rows, and the plant spacing is 37cm. There are about 3000 plants per acre. (3) Seat method: When digging the head of Shouwu, the big roots will be harvested, small roots will not be dug, and even the heads will be buried together. Old vines will be cut, water will be covered with grass, and management will be strengthened. The harvest will be harvested in the following year. In addition, when adopting the straight-inserting method, due to the fact that the selected vines are too tender during seed selection, a large number of deaths often occur, resulting in serious seedling deficiency, and methods of digging buds (roots to be taken) may be used to supplement seedlings and have a high survival rate. If the root block is very fine or it can be digged, strengthening the cultivation for the second year of excavation, the yield is higher, and the quality of the medicinal material is also better. The cultivation of Shouwu must be strictly controlled seasons, practice has proved that planting before and after Ching Ming is more appropriate. Can not exceed the "three days", such as more than "three volts days" planting Shouwu, the survival rate is rather poor. Field Management 1. Framed vines: Planting sheds or canopies that can be stretched out to the surface of the water by the waterside, and planting sheds or fence-type vines on a flat land, until seedling length 33.7 Cm will artificially lead the vines to the shed. Before the shed, we must cut off the excess side seedlings in time to maintain a new strong seedlings 1 to 2 sheds. Other tender foot shoots that have just been released are covered with mud. When artificially introducing vines to the shed (shelf), pay attention to the rotation of the rattan shed on the right and do not rotate the shed on the left. 2. Fertilization: Early light fertilization or no fertilization, because early in the inter-species short-term melon, vegetables, beans, before July, generally do not apply fertilizer to inhibit the vine, prevent excessive fertilization, so that Miao Teng grow. In the medium term (July-August), if the seedlings are too weak, 15% manure may be used to extinguish the seedlings, but if the seedlings are green and vigorous, they should not be fertilized. In the later period (September-October), Shouwu begins to flower, and its roots begin to grow. Phosphorus and potassium fertilizers should be reused. Plow a trench on both sides of the surface, about 15 gram per acre (pig manure), 30 kilograms of raw bran or about 30 tons of soil miscellaneous fertilizer, and bury the fertilizer after application. A manure or chemical fertilizer is applied every 15 to 20 days, so that the Miao Teng is prosperous and the roots grow rapidly. 3. After harvesting the short-term crops, it is necessary to strengthen management, such as lack of seedlings, to make up the seedlings in a timely manner, and then to promptly remove the weeds. After removing the vines from the shed (shelf), timely remove the foothold leaves and foot vines (ie lateral buds) and labor. Flowering, so that air and light, in order to facilitate the concentration of nutrients, promote the rapid growth of Shouwu potato. Prevention and control of pests and diseases Shouwu less pests and diseases, the main insect pests are scarabs and aphids, beetles can eat the young leaves of Shouwu, if found to be available dimethoate or trichlorfon, one or two mixed water 150 kg spray, continuous 2 or 3 times, The effect is good. Harvesting and processing Shouwu planted from March to June of that year can be harvested from February to May of the following year. If the annual income is delayed, the output can be doubled. There are two kinds of processing methods. Dig out the roots, wash the sediment, cut into thick slices of one centimeter and dry them until they are dry. In addition, the freshly harvested Shouwu will be washed with sediment and piled on the ground for 1 to 2 days. Then separate large, medium, and small slices, put them in the pot, and take them out until they are dry or dry with fire. It is cooked Shouwu. Shouwu rattan that is Chinese herbal medicine at night to cross the rattan, in the harvest of Shouwu, the removal of the top of the head, picking off the leaves, bundle the sun to dry enough to be sold. Shouwu Lutou, go shougen, wash impurities with clean water, dry feet broken pieces, for the system of Shouwu wine a good raw material.
