树干注射施药技术研究概况

对树干注射施药技术的原理、注药机械、特点、应用、关键技术等作了详细的论述。树干注射施药技术是依靠树体自身的蒸腾拉力或外力向树体内输入营养物质、生长调节剂、农药或其他物质,以达到防治病虫害、强化营养、矫治缺素症、调节植物生长等目的的一种方法。随着对树干注射施药技术原理和应用研究的深入、设备的改进、关键技术的解决,该技术已日趋成熟,并受到了广大果园和林木管理者的重视。

Trunk Injection Techniques with Chemicals

Trunk injection with chemicals is a method of passing inject supply nutrition liquid, plant growth regulators, pesticides and other substances in tree trunk relying on the transpiration pulling force and external force, it can be used to control tree disease and pest insects, strengthen nutrient supply, treat element deficiency, regulate plants growth. The theories,injection apparatus,(characters),applications and key techniques with the techniques of trunk injection of chemicals were introduced in detail. With the function of trunk injection and it's apply to practice study (thoroughgone), the injection apparatus improved, the key to the technique resolved, it has (already) come to mature and was paid more attention by many managers in the orchards and forestry.
