Basic principles and applications of trunk injection technique
Trunk injection technique has the advantages of accurate application,high utilization efficiency,low contact risk and less environmental pollution.When spraying and root irrigation of chemicals are difficult to play a role or cause pollution to environment,trunk injection is a more suitable method,and its development and application have attracted wide attention at home and abroad.The tree physiological principles of trunk injection technique and factors affecting trunk injection were summarized,the equipments and characteristics of non-pressure injection,pressure injection with drilling and micro-pressure injection both domestically and internationally were systematically introduced.Furthermore,the application of trunk injection in the prevention and control of diseases and pests such as pine wilt disease was also introduced,aiming to provide a reference for the development and optimization of trunk injection technique.
