Pueraria is a leguminous vine, which is a dual-purpose health food for medicinal use. It has the functions of detoxification, anti-inflammatory, analgesic, and summer cooling. It has preventive and therapeutic effects on hypertension, coronary heart disease, angina pectoris, diabetes, and obesity. It is commonly used as a medicinal herb. one. In the past two years, the products of Pueraria powder, Geliang tea, Gege fans, Ge jelly, Ge cakes and Ge beverages, which were developed using Pueraria as a raw material, have been favored by consumers. The market is very popular, making its social demand increasing. The development of Pueraria will have a broad prospect of production. Peasants' friends can be introduced and cultivated according to local conditions on the premise of finding a market. At present, the methods for cultivating Puerariae are different in different areas, but the cultivation yield is highest in alfalfa cultivation. The technical points are now described as follows: 1. Selection of land. Kugen adaptability, the requirements for the selection of sites is not strict, that is, can also grow in thin sandstone land, but the soil with deep, fertile sandy red soil growth is optimal. Therefore, we should choose a deep soil layer (thickness of 80 cm or more), a slope below 25 degrees, a well-drained hillside, and a dry land. We should not choose low-lying fields to cultivate Pueraria. 2. Site preparation. There are two types of site preparation methods: digging and soil preparation. Digging holes is relatively simple and easy to operate, saving time and labor. Digging holes must be cleared before the mountain field mixed wood, mixed with shrubs, all loose soil 15 cm deep, and then do 1 to 1.5 meters wide horizontal strips, and then dig in the strip 60 cm square cave, the distance between the cave according to planting The density is generally about 1.5 meters. It takes time for the sewer and land preparation, but weeding, ripping, and excavation of puerarin are relatively easy, and can be planted densely with high yield. Before digging trenches, it is also necessary to clear the mountain field for the miscellaneous irrigation, remove all weeds with loose soil, and then dig ditches along the contour line according to the terrain. The specifications are width and depth of 80 cm, the length is natural, and the ditch is 1 Meter. 3. Base fertilizer. After the land is well-prepared, base fertilizer should be applied to grow Pueraria. Cave preparation, 15 kg of manure or livestock excrement per hole or 25 kg of Shitang mud. In the sewer land preparation, put a layer of thin straw at the bottom of each ditch, and sprinkle some lime powder to facilitate the loosening and ventilation of the soil. Apply excrement or livestock manure to the excavated surface and soil. About 5,000 kilograms per 667 square meters of fertilizer To cast evenly so that when the topsoil is backfilled, the base fertilizer is thoroughly mixed with the surface and the soil. 4. Backfill the topsoil. After the base fertilizer is applied, the topsoil shall be backfilled and backfilled. When the backfill is completed, the soil shall be crushed and thoroughly mixed with the bottom fertilizer. The backfill soil shall be slightly arched above the ground. 5. Choose seedlings. The quality of seedlings directly affects the yield and quality of cultivation. When selecting the seedlings, the seedlings should be swelled and full, with seedlings with a small Gege. And the geek should be short and thick, easy to break, or choose two branches, thick branches, full-grown branches, root growth, no damage and pests and diseases Ge. 6. Planting. In order to improve the survival rate of planting, it is necessary to choose cloudy or light rain days to plant the seedlings along with them. At the time of planting, according to the size of Gemiao, digging a planting ditch on a previously-prepared geisha, and then placing Gemiao on the slope, swinging open, smoothing the stalks or fibrous roots, and making them tilt about 30 degrees. Angle, filling, pat compaction, and then cover a little bit of adobe into a head shape, so that the Getou branch slightly buried about 1 cm in the ground. 500 seedlings per 667 square meters is appropriate. 7. Planting time. Depending on the climate and climate, the Jiangnan region is generally better planted from March to early April. 8. Management. 1 pre-management. After 5 to 6 days, GE sprouts will sprout new shoots. When they grow to 3 or 4 rounds of compound leaves, they should carry out shallow hoeing and loose soil. At the same time, they should dilute the diluted human excrement slightly at the base of the GE seedlings. Do not pour in GE leaves. In order to avoid burns Ge Ye, Ge Teng, so repeated every 3 to 5 days, once poured a total of 3 to 4 times, Ge Miao will grow vigorously. 2 Mid-term management. When Ge Teng grows to 3 to 4 meters in length, it uses a decomposed pig or cow dung once, and applies 1 kilogram per plant, or applies a compound fertilizer once to a hole, and 100 grams per plant. It is applied once every 10 days (preferably not applied). fertilizer). Before the fertilization and after the fertilization, it is necessary to loosen the grass once and keep the weeds in the field. By the end of June and the beginning of July, GeTeng will basically cover the ground. Since then, the management has basically been to weed the grass, keep the weeds in Gochi, and prevent livestock damage and hare invasion. 3 late management. After the spring of the second year, we should promptly weed the soil once and apply a farmyard manure or compound fertilizer. By the end of April, GETO will be spread over the ground and the management will be more extensive. 4 pest control. Pueraea is relatively rare pests and diseases, mainly for a few years of continuous cultivation of Geqi there will be a small amount of Ge rust, spraying carbendazim or thiophanate-methyl solution for sterilization control. 9. Harvest. Pueraria is generally excavated in the fall and winter seasons of 2 to 3 years after planting. Select the sunny days to cut the vines first, then carefully dig up the roots and shake the soil. 10. Processing. 1 cut slices. After digging the fresh roots, they are cut into thin slices (0.2 cm thick) with a guillotine, sun dried or dried and bagged for storage. 2 processing Gefen. After Pueraria had been excavated, it was rinsed with fresh water, then crushed, placed in a container, added with appropriate amount of water, stirred thoroughly, and then filtered with a sieve of 80-100 mesh. The filtrate was placed in a sedimentation tank and precipitated and layered. The upper layer was an aqueous solution. The lower layer is Ge starch. After standing still for 24 hours, the upper aqueous solution was discharged, and the lower layer of Pueraria starch was dried or dried.
