In recent years, the plant growth regulator for crop production efficiency, simplify the labor, improve quality, make up for a lack of economic characters, resistance play an important role in such aspects as more and more be taken seriously. On 3th November, sponsored by the China association of pesticide development and application of the fifth development and application of plant growth regulator exchange meeting was held in chongqing, a number of experts in the field to share the research and application progress of plant growth regulator, new results, new demand.
The use of plant growth control technology and the use of the implant is becoming one of the most active fields in modern agricultural production, and its contribution to agricultural progress is improving continuously.The scientific, rational, correct and normative use of the implant has gradually become a clear indicator of the precision and precision of farmers' mastery of planting techniques.In practice, the understanding of the efficacy of regulation has been deepened, and more and more single products or combinations are used, and the resulting crop solutions have benefited the majority of growers.The industry is devoting great enthusiasm to the research and development, production and promotion of phytochemicals.
"The application of phytochemicals is one of the key measures to achieve zero growth of pesticides, quality enhancement and green control targets.To reduce the use of drugs in the context of ensuring production, it is important to use the plant's own resistance to reduce the occurrence of pests and enhance the absorption of nutrients, which can be achieved by the implant.Sichuan Guoguang Agrochemical Co., Ltd., said zhang jiangwen, minister of crop technology.
Production enterprises should focus on the resources integration, independent innovation, technology services, efforts to improve the quality of our products and specification product instructions, to speed up the registration of plant growth regulator on the characteristics of the minor crops, to provide quality and efficient plant dispensing products.The industry authorities should formulate industrial development plans for the whole industry and guide the orderly development of the industry through policy guidance and support.At the same time, we will work together to promote the popularization of science popularization and technical guidance.
"Plant growth will meet many adverse conditions for growth, such as cold spring, drought, etc., which urgently requires efficient and safe plant growth regulators."According to zhao xiaoming, a researcher at the dalian institute of chemical physics, Chinese academy of sciences, the anti-inductive agent of oligosaccharide has become an important direction in the development of the implant.The study and experiment found that oligosaccharide conditioner can improve crop resistance, cold tolerance, promote growth and improve crop quality.He believes that the "fat medicine reduction" action launched in China can play a big role in the treatment of the antiseant of oligosaccharides, which will play an important role in green agriculture.
Tian xiaoli, a professor of agriculture at China agricultural university, takes cotton as an example, and introduces the application of new techniques in intensive planting mode.She suggested that application of regulator seedling early onset, control of plant type, concentration and peach, chemical multi-topping, defoliation ripening, and so on, with good and reasonable fertilization strategy, density of cultivation measures, such as full mechanization of cotton production, cotton in xinjiang, hebei, shandong and other places has realized the machine mining and fully mechanized.The application of plant growth regulator can exert greater potential under intensive planting conditions.
"The integrated use of green plant protection technology based on the use of immunoassay has made up for the lack of a single product and has achieved good results.We are very confident that we will reduce the amount of chemical pesticides by 30 percent."Researcher at the institute of Chinese academy of sciences chengdu biological Tan Gong said that her team will also be immune induced resistant agent, physical and biological fungicide, insecticide and insect pests prevention and control technology, low toxicity, green chemical pesticides used cooperatively, set up the green plant protection technology integration and a variety of crops, decrease pesticide shi synergistic effect is remarkable and the promotion of quality and safety.
According to several experts, because of the high biological activity of the implant, precise control of usage is needed, so it is important to strengthen the correct professional guidance in the use link.
Sichuan Guoguang Agrochemical Co., Ltd. Crop technology minister said Zhang Jiangwen, planting adjust appear in practice use to reach the ideal effect, both crops itself factors, pharmaceutical, environmental and human factors.Take kiwi fruit as an example, different varieties are applicable to different doses, and some varieties such as jin yan, should not use clopidourea, even if the concentration is very low.It is also important to use the time period, such as the application of clopidourea to improve the yield of mango fruit, most of which are not effective at the initial flowering stage, and have remarkable effect at the end of the flowering stage.In addition, some growers to increase the dosage or concentration, use for pesticide registration of product, or use may contain ingredients for "invisible" illegal products, "filled with abundance medicine" is not scientific, normative, not only difficult to achieve the desired effect, even phytotoxicity causes unnecessary production loss will happen.
"Plant growth regulator is unique, safe and efficient, great potential, small products have great value, and there is an irreplaceable important role in modern agriculture, which has become an industry consensus."The new situation and demand requires that plant growth regulators have better products and more precise and standardized technology applications, said duan liusheng, director of the plant growth regulator's professional committee.Professional committee will further strengthen exchanges in the future cooperation, and will be Posting regular field of plant growth regulator, the white paper, at the same time to strengthen science popularization, in order to promote plant adjust better development and application.
