The tiger tail wheel can also be called Timothy, stone ginseng, cat tail shot, rabbittail grass, Tongtiancao and fox tail. It belongs to the perennial subshrub herb of the genus Corydalis, and it is a folk herb in southern Anhui. In the production areas of Fujian, Jiangxi, Hunan, Guangdong, Hainan, Guangxi, Guizhou, Yunnan and Taiwan, the artificially planted tiger tail wheel is not comparable to the wild tiger tail wheel in terms of efficacy and taste. The technology, that is, the imitation of wild forest undergrowth technology of the tiger tail wheel, is as follows. 1 Overview of the test site The test site is located in Hechun Village, Makeng Township, Hua'an County, Fujian Province. The frost-free period is 310 days. The annual average temperature is 19.8 °C, the annual average precipitation is 1 620 mm, the altitude is 500-630 m, the slope is southeast, the lower slope is lower, and the site type is Class I, soil thickness greater than 100 cm, humus thickness 12 cm. The forest is divided into Camellia oleifera forest, planted in 2008, with a canopy closure degree of 0.5, and an interplanting tiger tail wheel in 2014. The method is to use a 50 cm × 25 cm (width × depth) strip leveling method along the horizontal (contour line), the strip spacing is 1.5 m, and the ditch is planted at a depth of 2 to 3 cm. The seeding rate is 300 g/667 m 2 , and the soil is covered by 2 to 3 cm after sowing. 2 Tiger tail wheel seeding technology 2.1 Seed cultivation conditions and storage methods The tiger tail wheel should be selected from seeds that mature in October and have an orange-yellow color. The seeds need to be dried before being planted and stored in a cool and dry place. 2.2 Soaking seeds Soak for 4-6 hours with water of about 45 °C before sowing, and shake the seeds back and forth by hand, and remove the waxy layer of the seed coat. The seeds after soaking should be picked up, wait for sowing after drying, which is beneficial to the tiger tail wheel. The seeds sprout faster. 2.3 Sowing time Sowing in March-April requires a temperature of 20 to 30 °C, which is beneficial to the germination of the tiger tail wheel seeds. 2.4 Seeding method After sowing, artificial sowing, sowing seeds evenly when planting, generally about 300 g per mu of forest land. 2.5 Tending Management 2.5.1 Weeding: In the first year of seeding of the tiger tail wheel, weeding should be done more. After the seedlings of the tiger tail wheel grow, the seedlings can be gradually reduced, and in the second year or three, it can be reduced to no weeding. 2.5.2 Fertilization: Fertilization can not only provide nutrients for the growth of the tiger tail wheel, but also promote the growth of Camellia oleifera. The number of fertilization should be strictly controlled. It should be noted that chemical fertilizer should not be applied, but organic fertilizer can be applied in the first year of planting. 2.5.3 Pest Control: During the seedling stage of the tiger tail wheel, the mites will cause damage to the leaves of the tiger tail wheel, so pay more attention to prevention. 2.6 Harvesting It is mainly to harvest the roots. It is usually harvested in two or three years. It is best to harvest in the autumn. Be careful when harvesting, avoid damage and roots in the roots of the tiger tail wheel, wash away impurities and dry after harvesting. Storage. 3 Benefit Analysis Under the Camellia oleifera forest, the tiger tail wheel changed the planting mode of the tiger tail wheel to organically combine economic forest cultivation and Chinese herbal medicine production, making full use of forest land resources and promoting the economic development of the forest. 3.1 Ecological benefits The technique of cultivating the tiger tail wheel under the Camellia oleifera forest can save the grass step, help maintain the forest habitat, improve the soil nutrient content of the forest land, and increase the yield of the oil tea. 3.2 Economic benefits In the case of Camellia oleifera, the economic benefits will be higher than the traditional single tree planting and field cultivation alone. At the same time, it has the following advantages: the quality and market price of the high tiger tail wheel; eliminating the chemical weeding step can reduce the cost of medicine. With short-term growth, increase the utilization rate and output rate of forest land, increase the income of forest farmers, and at the same time, it can also be harvested multiple times, and one investment will benefit for a long time.
