Background
Ancient trees are known as activated fossils by people, and are increasingly valued by people in terms of unique scientific research, scientific popularization, history, humanity and travel value, but because the old trees are older, the activity is reduced, the resistance to weather erosion is weaker, and the extreme weather in recent years is more and more, important tests are generated on the survival of the old trees, so that in order to protect the old trees, the service lives of the old trees are prolonged, and the ecological indexes of the old trees are necessarily monitored.
The existing ancient tree ecological index monitoring technology can basically meet the current requirements, but has certain defects, and the existing ancient tree ecological index monitoring technology has the specific expression that: (1) The prior art lacks certain attention to the reinforcement method selection when the ancient tree meets strong wind, the ancient tree is big because the crown, when the strong wind is encountered, the problem that topples over easily takes place, consequently need consolidate, and the ancient tree is because the age is great, the ability of absorbing water also becomes weaker, the trunk that leads to the ancient tree sometimes can appear the condition that the wettability is insufficient, bark on the trunk is comparatively fragile, if use unreasonable reinforcement mode, then cause the harm to the trunk easily, lead to the ancient tree to receive artificial invasion, thereby reduce ancient tree life-span, cause the loss to the historical heritage in city.
(2) The prior art lacks certain concern to the ancient tree whether need irrigate or drain waterlogging, the ancient tree is because the influence of environment, the problem of lack of water appears easily, on the one hand, prior art just irrigates the operation when discovery lack of water, neglect the influence of weather, the condition that appears rainfall after leading to taking place the ancient tree irrigation easily, if the precipitation is great, lead to the soil humidity of ancient tree too high, the root system hypoxia problem of ancient tree appears easily, thereby improve the dead problem incidence of ancient tree, on the other hand can appear because of the rainfall, and the condition of not irrigating the ancient tree, if the precipitation is less, then the ancient tree still is in the state of lack of water, thereby influence the stable development of ancient tree.
(3) The prior art lacks certain attention to the strengthening sequence, the irrigation sequence and the drainage sequence of the ancient trees, the ancient trees in the cities are more and more scattered, management is not facilitated, when the ancient trees are required to be strengthened, irrigated and drained, the old trees are difficult to get timely and effectively salvaged due to insufficient hands, and the old trees with larger part of ages are difficult to get timely caused by insufficient hands, so that the health of the ancient trees is endangered, and the operation and maintenance difficulty of management staff is increased.
