Introduction of Origin Hongya County is located in the southwestern edge of the Sichuan Basin. It is located in the triangle of Chengdu, Leshan and Ya'an. The landform is dominated by mountainous hills and is known as the “Seven Mountains, Two Waters and One Field”. Good natural geographical conditions and a long history of Jardine's planting provide excellent conditions for the production and development of Jardine. In 2008, the planting area of ​​Yalian in Hongya County was 2,100 hectares, with an annual output value of 90 million yuan. It is the largest production and sales base of Yalian in China. Hongya County vigorously promoted pollution-free cultivation techniques in the cultivation of Yalian, and formulated a complete set of “Standards for Pollution-free Agricultural Products” and the “Local Technical Standards for the Production of Pollution-free Agricultural Products”, and established the Yalian Base 2000. Hectare. Endangered status quo due to the high altitude requirements of Yalian (1700 meters or more), strict soil requirements (mountain yellow brown soil rich in humus in alpine mountains), long rotation period (not planted with berberine plants for more than 20 years), long time in the ground (5~6 years), the difficulty in controlling pests and diseases (mainly rot-root disease) and other factors, resulting in low yield of Yalian, difficulty in cultivation, the medicinal farmers moved from Gaoshan District to Pingba, and the alpine region gradually became uninhabited. These factors have caused Yalian to become an endangered and rare species. From the point of view of economic benefits, because of the "mixing conditions", the planting conditions are lower than the requirements of "Yalian", the harvest period is short, the yield is high, and the economic benefit is higher than u0026quot;Yalianu0026quot; Even with quot;. By 1981, the production area u0026 quot; Weilian u0026quot; planting area has exceeded u0026quot;Yalianu0026quot; In 1986, the county u0026quot;Yalianu0026quot; was planted only 357 acres, while the "weilian" was as high as 3,122 acres. Later, the output of "Yalian" was reduced year by year. In 1992, the county planted 2510 acres of berberine, and "Yalian" only accounted for 5 acres, less than two thousandths. In the year, Huanglian purchased 16010 kilograms, u0026quot;Yalianu0026quot; was only 1200 kilograms.
