my country ’s key technologies for the prevention and control of wheat screen diseases are both high -yield and safe

On July 13th, the reporter learned from the Puyang City Science and Technology Bureau of Jiangsu Province that the Jiangsu Academy of Agricultural Sciences and Puyang Zhongnan Chemical Co., Ltd. combined with the use of modern biotechnology, and the risk of pollution risks and control of wheat sickle toxin pollution. Technical research and applications have made major breakthroughs, effectively solve the problem of "high yield and poisoning" industry, and developed new pharmaceutical Le Maibao. This year, it is expected to promote the use of more than 10 million mu. In 2020, the results of the research won the first prize of the Jiangsu Provincial Science and Technology Award.

"Two legs" from biochemical breeding and new pharmacy

Gao Derong, director of the Wheat Research Office of the Institute of Agricultural Sciences, the Lower River area of ​​Jiangsu, introduced that wheat giant mold disease is a global disease caused by Henan sickle bacteria. It is also known as the "cancer" of wheat. Fungine toxins also pollute food and feed, which seriously threatens human and animal health. The foundation of wheat sickle is difficult and difficult to control.

"In our country's wheat planting area, chemical methods are generally used to inhibit the retransmission of gyro mold. Sometimes applying three to four chemical pesticides still fails to achieve the expected results. In addition, the use and residues of a large number of chemicals increase costs, which both increase costs. Destroy the ecological environment and bring potential danger to food safety. "Gao Derong said.

In the past year, in order to effectively reduce the harm of the villain sickle toxins, Chinese scientists have adopted molecular labeling supplementary breeding technology to accelerate the selection of new and high -quality high -quality wheat varieties, such as the Institute of Agricultural Sciences, Lower River, Jiangsu. Yangmai 33 and other high -resistant high -resistant products lines; it is difficult to start from concentrating to overcomes the control of the toxin toxin toxin, and accelerate the screening of high -efficiency bacteriostatic and poisoning agents. For example The azoholtoleol suspension, etc., effectively guarantees wheat output and food safety.

Accelerate the transformation and demonstration and application of achievements

"In the past, it was mainly focused on the prevention and control of wheat disease. After prevention and control, 60 % to 70 % of the output could be recovered, but the content of wheat toxin was still exceeded. Our scientific research team focused on the risk formation and control technology of the risk of poisoning of sickles." Jiangsu Shi Jianrong, Institute of Agricultural Product Quality and Safety and Nutrition of the Provincial Academy of Agricultural Sciences.

How to solve this problem?

The scientific research team of the Jiangsu Academy of Agricultural Sciences started from solving toxins, and invented the key technologies of the preparation and high -throughput accurate identification of Sydromesida toxin, developed eight standard substances with independent intellectual property rights, and achieved 33 synchronous testing of toxins. At the same time, the team also developed a suitable on -site non -destructive testing equipment. In 1 minute, it can determine whether the toxins in wheat exceed the standard and meet the production and supervision needs of fast and lossless testing.

"The team detected more than 20,000 wheat samples from 98 % of the nationwide wheat area, and established the national pollution database of wheat sickle bacteria. During 40 years, the evolution of poison -producing sickle bacteria groups found that poisonous sickle bacteria in Jiangsu region takes 3adon chemical type as the dominant population, with deconstructing the function of the toxin toxin toxin toxin, to screen out the efficient bacteriostatic poison and reducing agent, and through the production of production Learning and research cooperation to accelerate the transformation and industrialization of new results of scientific research.

In recent years, through the integration and innovation of various key technologies, the scientific research team has created a full -process control technology system with measures to prevent and control the drug control and reduce virus and reduce the virus -reducing virus -reducing virus -reducing virus and reduce the use of postpartum toxin monitoring and reduction measures. A significant reduction of toxins exceeds the standard wheat.

"For more than 10 years, our company has developed positioning in accordance with the" efficient, low toxic and low residue ', focusing on the production of biological pesticides and non -biological pesticides, and has invested more than 30 million yuan. On the one hand, it actively participated in the research of new pharmaceuticals and accelerated equipment technology transformation. Under the guidance of experts throughout the process, a large number of indoor research and field test demonstrations were carried out simultaneously to prove that the new pharmaceuticals have high control effects on wheat's scruited, rust, and powder disease. The production area, the demonstration area of ​​more than 5 million mu, of which 500,000 acres of wheat in Changzhou achieved full coverage. This year, it has been promoted about 10 million acres.
