College students return to their hometown to start a business and adhere to the ecological planting method.

On a summer night, Luo Yizhong, 28, general manager of the Longzhikang planting Cooperative Dendrobium Plantation in Hengxi Town, Xianju County, and members turned on flashlights to find the natural enemy snail.

In 2011, after graduating from Yizhong University, Luo Yizhong returned to his hometown of Hengxi to work as a farmer. He chose to plant Dendrobium candidum as his entrepreneurial road. He created a set of organic Dendrobium candidum planting method: "No application of chemical fertilizers, no spraying of pesticides, manual weeding, hand catching insects, and five years of picking." Over the past five years, he has adhered to his own planting principle, and the organic Dendrobium candidum has become a fine product on the market. Recently, the "Longzhikang" cooperative received a sampling inspection report from the quality supervision and testing agency of the Ministry of Agriculture, and the test results were "undetected" and far lower than the national heavy metal content standard for pollution-free fruits.
