Cinnamomum camphora pest control

High-value trees

Cinnamomum camphora is a large evergreen tree that can reach a height of 30 meters and a diameter of up to 3 meters. Mainly distributed in southern China, it is an important economic tree species in the subtropical region, and all plants can extract camphor oil, which can be used as raw materials such as pesticides, soaps, and flavors. At the same time, camphor is also the main raw material for the production of camphor.

Grows in subtropical mountainous areas

Cinnamomum camphora is suitable for sunny slopes, valleys and riverbank flatlands with fertile subtropical soils, and the camphor forests in Shixing County, Shaoguan City, Guangdong Province are distributed in mountainous areas. Due to the steep terrain and high leaf density in mountainous areas, traditional artificial plant protection faces problems such as inconvenient walking, low safety factor, high spraying difficulty and low efficiency.

The effect of flying plant protection is good

In July 2016, Guangdong Qingyuan Jujin Plant Protection Team (hereinafter referred to as Guangdong Qingyuan Plant Protection Team) made flying plant protection for Mr. Chen's 300 acres of camphor, and achieved good results. In August, Mr. Chen introduced the Guangdong Qingyuan Plant Protection Team to another colleague, Mr. Hua, who also struggled with the plant protection of mountain camphor forests.

Wu Yongguang, the captain of the Guangdong Qingyuan plant protection team, co-founded a multi-rotor drone sales and service company with a friend in 2015 and entered the plant protection service industry. At the beginning, Wu Yongguang saved his own plant protection machine, but the stability of DIY products was poor. In 2016, after DJI launched its agricultural plant protection machine, the Guangdong Qingyuan plant protection team immediately purchased two MG-1s, and the team trained five plant protection pilots to work on corn, sugarcane, camphor, rice, mulberry and other crops. "The MG-1 has stable flight, higher reliability and better maneuverability than its own DIY plant protection aircraft," said Wu Yongguang.

In order to operate the camphor forest growing in the steep mountainous terrain, the Guangdong Qingyuan plant protection team tried their best to try to operate the camphor forest at the foot of the mountain, but the mountain altitude was too high, which was not conducive to the observer to observe the flight situation of the MG-1.

Operational efficiency

One MG-1 basically completed the operation of 200 mu in one day, which is more efficient than the traditional manual operation, and avoids the personnel climbing operation and improves the operation safety. According to Mr. Hua, the farmer, the prevention and control effect reached the standard.
