Where is the hometown of Douban?

98% of the soil in Pidu District belongs to gray alluvial fluvo-aquic soil, slightly acidic, with pH of 6.5-7.0 and organic matter content of 2.3%-3.0%. Among them, fertile and loose oil sand fields and mud fields account for more than 80%, which are suitable for the growth of crops and cash crops, especially for the growth of red pepper and kidney beans, the main raw materials of Pixian watercress.

It belongs to subtropical monsoon humid climate, with no heat in summer, no cold in winter and abundant rainfall. Located in Dujiangyan gravity irrigation area, the territory is flat and fertile. Eight rivers, such as Baitiao River, flow in parallel, creating a natural endowment that floods and droughts follow people and there is no hunger at times. The unique geographical environment provides superior natural conditions for the unique Pixian watercress production, and Pixian is known as the hometown of watercress in China.

Selection method of watercress

1, you should choose Pixian watercress produced by regular manufacturers in the regular market, and don't buy three no products. Because of the quality system certification, product quality is more guaranteed. We recommend Juancheng brand, Dandan brand and Shufu brand. Each brand has its own series of products, such as red oil watercress (with more red oil), chop-free watercress (chop-free and convenient) and refined watercress (aged for many years). There are also small packages, one package at a time is very convenient, and you can choose according to your own needs.

2, look at the production date and shelf life Many people think that Pixian watercress is fermented food anyway, and the length of time does not matter. In fact, food is easily contaminated during storage and transportation, so be sure to see the shelf life clearly.

3. Choose Pixian watercress, which has bright red oil, brownish red color and mellow smell. Some inferior and fake Pixian watercress, with dim color and many impurities, must be paid attention to.
