Tianqi, also known as Panax notoginseng, is rooted and rhizomes are used as medicinal herbs. It is a perennial herb of the Araliaceae family. First, the growth environment: Tian Qixi warm, afraid of cold and hot, hi wet, afraid of water. The summer temperature does not exceed 38 degrees. Winter can be planted at minus 10 degrees, and 18 to 25 degrees is suitable for growth. Tianqi grows best in loose and fertile, well-drained sandy soil and oil sand soil: yellow mud, brown color, and low-lying land should not be planted. Avoid continuous cropping. Can not be planted in the former crops for solanaceous plants such as buckwheat and vegetables. . Second, the cultivation techniques: Tian Qi should be from November to February, when the fruit is ripe, full of seeds without pests and diseases. Red edge mining, remove the peel. Clean: With the harvest with the broadcast, if not timely sowing, seeds can be placed in the sieve, put cool and ventilated place to save, such as Sinotrans, can remove the peel, mix in 2 times wet sand, stored in the water tank can be Cars; if self-retaining species can be opened on the whole floor; the length can be determined according to the terrain. Cab width 80 to 85 centimeters, height 20 to 25 centimeters, and the back of the car is tile-shaped. After the car is opened, the spacing is 6.5 centimeters. The spacing between the plants is 5.7 to 6 centimeters. The seeding is based on the seeds. Months after emergence. After the planting in March, the planting method can be used to start the planting. Note: Do not injure the root when taking seedlings. When transplanting, the whole car is horizontally grooved, flat at the bottom, 2 cm deep, and wide enough to put down seven fields. The buds are sloping down the slope, and the backslopes are turned upside down. The line spacing is 13 to 17 cm. Can also be transplanted with two plants, while planting side cover manure, to cover buds and hoe is appropriate, about 3.5 cm thick, and then cover the grass, to not see the soil is appropriate. After June, remove the cover grass, remove debris, and remove the grass. Tian Qi is a shallow-tillage crop and is generally not tilled, but each time it rains or when the humidity is too high, it is necessary to loosen the soil and increase soil permeability. And pay attention to more fertilization, should be appropriate multiple times. For the first time during leaf spreading, 200-250 kg per acre of composting fertilizer is applied once a month and then from May to August, 200 kg of defecate water will be chased monthly. From September to October, a cover bud fertilizer will be applied to protect the buds. Promote long. In addition, there should be no accumulation of water in the park, and the water outside the park should be unobstructed. To reduce the consumption of nutrients and increase the yield of rhizomes, plant species that do not remain in the garden should be picked on a sunny day in July to pick off the moss. It is better to have no rain in the next two days. Third, pest and disease control: 1, blight: from April to May low temperature and rainy and July to August high temperature and drought prone to occur, the beginning of the petiole base stains stripe spots, when severe dark brown shrinkage to seedlings. Control methods: 1 before sowing with acres with 1 kg of chloronitrobenzene to treat the soil; 2 Seeds soaked with 1:1:1 100 times Bordeaux mixture sowing seeds for 10 minutes; 3 at the beginning of the use of pentachloronitrobenzene 200 times Liquid irrigation ward. 2, according to rot: also known as "chicken rotten" is a devastating disease in the late Tian Qi. When the disease occurs, the root rots, with odor, prevention and control methods, no disease-free strips during transplanting, timely drainage in the rainy season, remove the diseased plants in time, and water the wards with Dow Miaoling 1000 times liquid. 4. Harvesting: Harvesting can be carried out in two years after transplanting. The time of excavation should be from October to the time before sprouting. However, the quality of Spring 7 harvested before the field is the best. 5. Processing: Remove the stems and leaves from the harvested fields and wash the soil. Cut off the roots and fibrous roots of the head of the head (sheep intestines). The rest is called the head. Let the head dry for one day. Rub it for the first time. Use light force to avoid breaking the skin. Repeat the sun and rub it. Peel the skin until it is completely dry. It is not only wool goods, but also joins the sacks with rice cargo and makes a round-trip collision so that the appearance is brownish-black and bright. It is a finished product, and the cut heads, roots, and fibrous roots are sprinkled dry, and the goods are cut, ribs, and fields. When it is cloudy, you can dry it separately and sell it together. Can increase economic income.
