1. He has made important achievements in the research of chemical weed control
In view of the phytotoxicity caused by unreasonable mixing (mixing) of herbicides to crops, especially hidden phytotoxicity, Conducted "Research on the Joint Effects and Mechanisms of Mixed Pre-emergent Paddy Field Herbicides on Rice Safety", proposed "Types and Evaluation System of the Joint Effects of Mixed Pre-emergent Paddy Field Herbicides on Rice Safety", and revealed the formation mechanism. At the same time, it also A batch of combinations with detoxifying effects were developed. This achievement laid a theoretical foundation for the scientific research and application of herbicide mixing (mixing). It is of great significance and practical value. Experts in the same field unanimously believe that this achievement has reached the international advanced level. , and won the second prize of Hunan Province Science and Technology Progress Award in 2002 (ranked 1st).
2. Outstanding achievements in the research and application of scientific mixing of chemical pesticides
He presided over the development of 6 new mixed pesticide products: 35 propyl benzyl wettable powder, 23 isopropyl ·Benzyl wettable powder, 15 acetobenzyl wettable powder, 25 toxin·azophos emulsifiable concentrate, 40 dichlorobenzyl wettable powder and 30 toxin·inhibitor emulsifiable concentrate have all been approved and registered by the Ministry of Agriculture and are available in Hunan, Hubei, Jiangxi, etc. The province has promoted more than 50 million acres in total, which has produced good social and economic benefits; octadecyl trimethyl ammonium chioride (1831 for short) has been used in the control of citrus sagittal scales and Brassicaceae. We have conducted research on various crop diseases and insect pests such as diamondback moth and rice blast, and have developed stable and feasible control technologies. Its preparations have been registered as pesticides by the Ministry of Agriculture (Registration Certificate No.: LS20051418); Duowei scientifically combined with organophosphorus chlorpyrifos and successfully developed 35 poison emulsifiable concentrate. This product has been widely promoted and applied in cotton areas.
3. Important discoveries have been made in the research of botanical pesticides
“Resource screening and mechanism research of plant safeners for amide paddy field herbicides” was awarded the National Natural Science and Technology Award in 2002 With funding from the foundation, three plant materials with strong detoxifying effects on acetochlor and metolachlor were screened out, and three national invention patents have been obtained. "Optimization of the Action Mechanism and Structure of Active Ingredients of Rhizoma Rhizoma Inducing Rice Resistance to Rice Blast" was funded by the National Natural Science Foundation of China in 2007. The active ingredients and action mechanism of plant-derived inducers are being studied to determine the chemical structure and physical and chemical parameters of the active ingredients. and analysis methods, and form a refined processing technology for plant-derived inducers to be industrialized as soon as possible.
4. Accumulation of major work in the prevention and control of hemp diseases and insect pests
Since 2004, we have cooperated with the Ramie Research Institute of Hunan Agricultural University to carry out "ramie low-branch cutting high-efficiency breeding and supporting cultivation technology" Research", mainly responsible for research on weed occurrence patterns and control techniques in newly planted ramie fields. The results are planned to be appraised in 2009, and he is the fourth person to complete the project.
The application technology of ramie field herbicides was studied from 2002 to 2004, and the high-efficiency herbicides "Gaicaoneng", "Jinghecaoke" and "Fengcaoke" suitable for ramie field application have been screened out. Shangai Caoling" and supporting application technologies have effectively solved the problem of weed damage in ramie field production.
From 2003 to 2007, he conducted the "Research and Demonstration of Key Technologies for Winter Flax Industrialization in the Southern Red Soil Area" in Qiyang County, Hunan Province, mainly responsible for the occurrence patterns of weeds in flax fields and the research and development of new herbicides, as well as the research and development of new herbicides for flax. The research, development and promotion of chemical lodging and anti-lodging agents (maleicides) passed the achievement appraisal organized by the Hunan Provincial Department of Science and Technology in 2005 and reached the leading level at home and abroad. Since 2007, in Anxiang County, Xinshao County and other places in Hunan Province, we have cooperated with the Ramie Research Institute of Hunan Agricultural University and Hunan Anchengyuan Flax Industry Co., Ltd. to carry out "research and development on topping, bud suppression and lodging technology in the late growth period of flax". Demonstration" (applying for national invention patent, I am the third inventor), responsible for the screening and application technology research of flax sprout inhibitors.
In conjunction with ongoing research projects, the company went deep into ramie producing areas to provide technical guidance on pest and disease control: guiding farmers in Dongting Lake ramie producing areas to scientifically prevent and control the occurrence of termites, reducing the harm caused by termites; guiding farmers in ramie producing areas to scientifically use pesticides to control ramie roots. Important pests and diseases such as rot worm, ramie exigua, ramie yellow butterfly, ramie beetle, scarab beetle, etc. have achieved good social and economic benefits.
