Take the measures of "three exchanges" to increase the yield of Gastrodia elata

Gastrodia elata is a good traditional Chinese medicine, which has been selling well in the market in recent years. The majority of farmers in Chalu Village, Baoshan Town, Fengcheng City, Liaoning Province regard the development of Gastrodia elata production as an important way to get rich. more than 40 farmers in the village plant Gastrodia elata and have considerable income every year. Li Jingrong, a retired cadre in the village, has planted Gastrodia elata for 14 consecutive years and has accumulated a wealth of experience. He found that the yield of cultivated Gastrodia elata decreased year by year. There are three main reasons: first, it is seriously degraded due to the use of self-propagating and self-breeding strains every year; second, due to the continuous use of self-propagating and self-breeding strains, the bacteria are aging, the hyphae is not prosperous, and the vitality is weakened, so that Gastrodia elata is undernourished; third, long-term use of the same piece of land, it is easy to produce diseases, affecting the growth of Gastrodia elata. In order to solve the above problems, Li Jingrong studied jointly with local experienced flax farmers and decided to adopt the "three exchange" measures:

One is to change. The artificial cultivation species was changed to a new crop of wild flax seeds every 2023 to solve the problem of hemp seed degradation.

The second is to change bacteria. It is to change the self-propagated and self-bred strain to a new wild strain every 2023 to solve the problem of strain degradation.

The third is to change land. It is to use the same piece of land year after year and plant a new piece of land every 2012. Last spring, 20 households in the village planted hemp and adopted the "three exchange" measures, all of which achieved remarkable results.
