Pingwu Tianma has a long-standing reputation, and there is a saying that "the local product is suitable for medicine." In the Tang Dynasty, Pingwu Tianma was handed over to the country as a tribute. The average content of gastrodin in Pingwu Tianma is over 0.4%, which is twice the 0.2% of the Pharmacopoeia 2010 edition, up to 0.98%.

Before being protected, the county cultivated a total of 165,700 nests of Tianma, with an area of ​​200,000 square meters and an annual output of 80 tons of dry days. After being protected, the county has cultivated 200,000 nests of Tianma, with an area of ​​300,000 square meters, and an annual output of 90 tons of dried Tianma, leading the per capita annual income of 2,000 yuan. Product awards Pingwu Tianma was named Mianyang's first most popular specialty agricultural product at the end of 2012. It was named as “Mianzhou Jiubao” and participated in the 11th and 10th in Hong Kong in 2012 and 2013 respectively. The 2nd International Exhibition on Modern Chinese Medicine and Health Products.

Pingwu Tianma quality technical requirements First, varieties Wutianma, red Tianma, Wuhong Tianma hybrids. Second, the site conditions Within the range of 1000 to 2500 meters above sea level, the soil is yellow brown soil to dark brown soil, organic matter content ≥ 3.5%, pH value 5.5 to 6.5, humus layer ≥ 1cm, environmental Yangshan area. 3. Planting and management 1. Cultivation and retention of hemp species: (1) Sexual breeding: use a single weight of more than 150g native to Pingwu County, short and robust, no pests and diseases, no damage, no decay, and complete buds. No abnormalities of arrowheads for planting hemp. Seeds will be planted, and after planting, artificially the same variety or red-flowered Tianma will be pollinated. After the fruit is ripe, it will be planted on the bed in time. Carefully manage the temperature and humidity, and take the seeds before cultivation in the next year to ensure the growth time of the hemp species. The hybrid Tianma of Wutianma and Wuhong is not less than 16 months, and the red gastrodia is not less than 6 months. (2) Asexual reproduction: In the cultivation conditions, the first to third generations of white peony and rice sesame, which are asexually propagated in the hybrid gastrodia elata, red gastrodia elata and black-red, are used as hemp species. 2. Preparation of honey fungus, germination bacteria and fungi: According to the production routine of fungal strains, the first to third grade cultures are carried out. The third-stage strain is directly used for production. In early March, the fungus or the fungus is cultivated according to the ratio of 30:1 bacteria and strain; before the mid-May, the fungus breeding bed or the fungus is cultivated. From mid-July to the end of August, 50% of the bacteria and strains were cultured to produce honey-stained fungi and fungi. 3. Planting: (1) Planting time: From the beginning of November to the beginning of March of the second year, the most suitable planting time is from the beginning of November to the end of December of that year. (2) Preparation of planting land: The flat land of the mountain forest with a canopy density of 50% to 75% or the slope of 45 degrees should be selected. Under the forest, the planting hole with length ≤ 2m and width 0.4m to 0.6m should be excavated according to the terrain. It is convenient for the use of bacterial strains. Dig the soil at the bottom of the hole to a depth of 15cm, flatten the excavated soil, and then lay a layer of 3cm to 5cm thick natural leaves, thinly layered with fine soil or fine humus, under the forest The total area planted must not exceed 10% of the forest area. (3) The next species: in the planting hole, the honey fungus that has been cultured is placed at intervals of 20 cm, and the fungus is left in the gap of 8 cm to 10 cm wide for 4 weeks. When the hemp is placed, the contact surface with the honey fungus is as large as possible. After planting, fill the gaps in the holes with fine soil or fine humus soil, lay a layer of fallen leaves, cover with humus soil, and finally cover the moisturizer with leaves that naturally fall off. (4) Management: Drainage should be opened according to the terrain to prevent water accumulation in the cave. Pay attention to irrigation and moisturization during drought, prevent rodents and insects, and prevent human and animal trampling. 4. Environmental and safety requirements: The use of pesticides, fertilizers, etc. must comply with relevant national regulations and must not pollute the environment. 4. Harvesting The harvesting time is from the end of October to the beginning of March of the following year. From October to now, 12 is the best harvesting time of the arrow hemp to ensure that its growth time is not less than one year. 5. Processing and washing the arrow hemp into steamed, steamed to the heart, 60 to 80 degrees dry until the surface of the gastrodia wrinkles, then tightly sweating until the gastrodia epidermis becomes soft, dry again, until the surface of the gastrodia is wrinkled again, then sweating, and finally dry To moisture ≤ 13%. Sixth, quality characteristics 1. Sensory characteristics: (1) Fresh gastrodia: oval, imitation hammer, long oval or long strip, ring pattern multiple round, point-like dense, sometimes visible brown fungus. The body is firm and heavy, with a top bud on one end and a round scar on the other end, commonly known as the "belly button." The horse has a strong urine. The chew is crisp and sticky, and the taste is sweet and then sinful, and its taste is difficult to disappear in the mouth for a long time. (2) Dry Tianma: long oval or long strip, flat, shrinking and slightly curved, ring-shaped multiple rounds, dense point, solid body, heavy, difficult to break, visible top buds and round scars. The horse has a strong urine. 2. Physical and chemical indicators: gastrodin content ≥ 0.40%, moisture ≤ 12.8%, total ash ≤ 4%, and extract ≥ 10%. 3. Safety and other quality technical requirements: Product safety and other quality technical requirements must comply with relevant national regulations.
