"School-enterprise-government" jointly explores precision application technology for volume reduction and efficiency enhancement

Recently, China Agricultural University and Linyi City Plant Protection Station jointly carried out a trial test of reducing dosage and increasing efficiency in Taiping Town, Linyi City, Shandong Province
.
China Agricultural University is responsible for pesticide application technology, Linyi City Plant Protection Station is responsible for crop pests and diseases monitoring and pesticide selection, Shandong Yongjia Power Co.
, Ltd.
is responsible for providing efficient and accurate self-propelled boom sprayer equipment, and "school, enterprise and government" jointly promote The integration of agricultural machinery and agronomy explores the systematic precision application technology plan: that is, choose green and low-toxic chemicals in the best control period, and achieve the ideal control effect by using precision application technology and high-efficiency plant protection machinery
.
? The zero-growth action of pesticide use requires reduction and efficiency enhancement.
It is necessary to reduce the use of pesticides and improve the control effect.
This is inseparable from the use of precision pesticide application technology and high-efficiency plant protection machinery
.
Shandong Yongjia Power Co.
, Ltd.
, as the leader unit of the National Agricultural Self-propelled Plant Protection Machinery Technology Innovation Alliance, takes the initiative to guide farmers to use plant protection machinery and control methods and technologies
.
"As a special agricultural machine, plant protection machinery is not equivalent to ordinary agricultural machinery.
It is not that the greater the horsepower, the better, the wider the spray range, and the more fog, the better
.
A qualified plant protection machine can not only walk, but also The important thing is to be able to accurately administer drugs and have a good control effect
.
" said Qi Peng, director of the company's precision application laboratory
.
? With the continuous improvement of people's awareness of protecting the ecological environment, the research on pesticide application technology and its application equipment is facing two major issues: how to improve the efficiency and effective utilization of pesticides; how to avoid or reduce the impact of pesticides on non-target organisms.
Pollution to the environment
.
At present, China's pesticide application equipment and technology are still relatively backward, and the effective utilization rate of pesticides is only 36.
6%
.
Most of the pesticides are lost to the soil and the environment, which not only wastes the liquid medicine, but also seriously pollutes the environment
.
For this reason, improving the spray performance of the nozzle, especially the spray uniformity, is extremely important for optimizing the application technology of agricultural chemicals, controlling the drift of harmful substances, improving the effective utilization of pesticides, reducing environmental pollution, and effectively using water resources.
Realistic meaning
.
? There are many reasons for poor spray uniformity, such as spray pressure conditions, nozzle spacing, nozzle height, nozzle characteristics, operating environment and working conditions and many other factors are different, and the influencing factors of spray quality are also complicated
.
In the process of pesticide spraying, part of the pesticide droplets will be carried by the airflow to the non-target area and cause drifting
.
With the increase in the amount of pesticides, the problems of animal and plant phytotoxicity and environmental pollution caused by the loss of pesticides have become increasingly prominent
.
Carrying out the test of pesticide droplet loss is of great significance for guiding pesticide application methods, researching and developing high-efficiency pesticide application equipment, improving pesticide utilization efficiency, and reducing the impact of pesticides on non-target organisms and environmental pressure
.
Pesticide loss is a complex problem.
There are many factors that affect the loss of droplets, such as the characteristics of the chemical liquid, the application equipment and the use technology, meteorological factors, and the operating skills of the operator
.
During the experiment, different spraying methods were used to test the uniformity, penetration, coverage and other data of pesticide deposition, and the data of pesticide drift and other data were tested for different spray modes
.
Song Jianli, associate professor of China Agricultural University and secretary-general of the Plant Protection Machinery and Medicine Application Committee, said that this test is closely related to actual combat, the method is scientific and comprehensive, the organization and coordination are efficient, the cooperation is tight, and the advantages of each family are used to achieve a strong alliance.
, Which favorably promoted the zero-growth action of pesticide use
.
The test equipment provided by Shandong Yongjia Power Co.
, Ltd.
has stable performance and can provide guidance for the scientific use of advanced and precise high-efficiency plant protection machinery in the future
.
? This event is organized by the National Agricultural Innovation Alliance self-propelled machinery plant protection science and technology, the development of Chinese pesticide and plant protection professional committee and pesticide application technology applications Association, the China Agricultural University, Linyi City of Plant Protection, Shandong Yongjia Power Co.
, Ltd.
jointly organized
