Non-toxic biological pesticides have been successfully developed
According to a recent news report from South China Agricultural University, at the award ceremony for the “National Award for Invention and Entrepreneurship,†the country’s highest award recently held, Professor Xu Hanhong’s invention of a non-toxic pesticide has won the prestigious award. Biopesticides were extracted from plants and the study of the "plant insecticide azadirachtin" was introduced into China and non-toxic pesticides were produced. “Today's food safety has been highly valued by the whole society. The international testing of green food imports has also become increasingly high standards. Pollution-free biological pesticides are an inevitable trend. We are very fortunate that in this market, we have 80% of the patent rights," said Professor Xu. Talking about the economic benefits of such non-toxic pesticides, Professor Xu said that 40 trees per mu can produce nearly 500 kilograms of "Azadirachtin" during the high yield period, with an average price of 4 yuan per kilogram. After the plant grows up, it can extract eight-thousandths of azadirachtin per 500 kilograms of fruit and therefore has a very high value and is called “green goldâ€. It is precisely because of the difficulties it takes. Therefore, when it is sold as a non-toxic pesticide, the price is about 30 higher than that of ordinary chemical pesticides. The reporter learned that Prof. Xu Hanhong’s research results have led to the promotion of large-scale cultivation of Nepenthes hirsutum and African taro. The introduction of Neem was considered to be another innovation after the rubber revolution in China. Today, Yunnan Province has identified this non-toxic pesticide as a pillar industry in the 21st century in Yunnan province and has grown to nearly 300,000 mu. It is reported that the next step, the production base of non-toxic pesticides will be introduced into Guangdong, currently tentatively scheduled to be in Heping County, Heyuan City, Leizhou Peninsula, Guangdong Province and other places.

Standard projects of layer cages for Layer Chicken Cage(Chicken Layer Cage) and are designed to meet all kinds of requirements for such structures. Mechanization and automation of the processes of feeding, watering, litter removing, egg collection and other technological processes greatly facilitate the work of the poultry house staff,and reduce the number of involved employees. It results in reduction of production costs per production unit.
