Revegetation Study of Adobe Dam, Phoenix, Arizona. Task 6. Evaluation of Three Watering and Mulching Techniques on Transplanted Trees at Adobe Dam

摘要

On the basis of these transplant studies, it is recommended that a minimal irrigation schedule be followed in the future for transplanted specimens. Transplanting early in the year reduces the watering requirements. Furthermore, after a one month adjustment period, trees watered once a month did well. Removal of supplemental water should be gradual, so as not to cause shock to the trees. Stone mulch appears to be both durable and effective as a mulching material, and can be cost effective if readily available on site. Fencing is a requirement for Palo Verde and Mesquite transplants but can be foregone on Cresote. Management following transplanting should include regular site inspections for signs of insect infestation and for watering problems. Inspection personnel should watch for signs that transplants have been watered adequately and that fences are intact and not restricting tree growth.
