Mid-rotation diagnosis and management options for correction of water and nutrient deficiencies in plantation-grown eucalypts

这项研究将通过改进目前对营养失调和水供应的诊断技术(叶片和土壤分析)来提高蓝莓种植园的生产力。利用一种新的韧皮部取样和分析技术，我们将开发一种快速、廉价、坚固和可靠的养分(例如N、P)和水分诊断程序，供田间使用。一项重大创新将是将缺水对增长的影响与其他增长影响区分开来。总体而言，该项目将在轮作中期的理论、概念和实践方面取得重大进展，为具有相当大商业前景的人工林进行诊断。

This research will improve productivity of bluegum plantations by improving current diagnostic techniques (foliage and soil analysis) for nutrient disorders and the supply of water. Using a novel phloem sampling and analysis technique, we will develop a nutrient (e.g. N, P) and water diagnosis procedure that is quick, cheap, robust and reliable for field use. A major innovation will be distinguishing the effects of shortages of water on growth from those of other growth influences. Overall, this project will provide a highly significant theoretical, conceptual and practical advance in mid-rotation, diagnostics for plantations with considerable commercial promise.
