Qiakou Scientific Research is composed of a team of masters and doctoral students in materials science from Tsinghua University and a team of professional farmers. The company was established in 2018 and is committed to developing non-chemical pesticide materials: carbon crystal plant protection preparations and post-harvest preservation technology for fruits and vegetables to help farmers improve the yield of agricultural products. Reduce agricultural supply chain losses. Our team independently developed carbon crystal ball chelated complex plant essential oil active extract. It is a natural and safe preparation that is used in field plant protection and post-harvest preservation of fruits and vegetables. It has been commercialized and has passed the registration-free plant protection materials by the Prevention and Inspection Bureau of the Council of Agriculture. Review (Plant Protection Registration No. 00600), and complete verification of a variety of high-economic items including mango, strawberry, coffee, etc., mainly targeting stubborn fungal diseases such as anthracnose, gray mold, leaf rust, etc., as well as insect damage that can cause peel damage The fruit powder is uniform and fine. Under the influence of extreme climate, it can effectively increase crop yields by 20-30%, reduce the cost of traditional pesticides and other materials by more than 10%, increase the safety of agricultural products, and strengthen the competitiveness of domestic and foreign sales. It has been commercialized since the end of 2021. The total application area is nearly 100 hectares of orchards, and the output value of processed fruits and vegetables exceeds NT80 million. It was also interviewed and promoted by Sanli TV Station’s Big Future program.
