Definite group of Longxing trees and comprehensive treatment of the causes of diseases and insect pests of
This species, which led to the outbreak of pests. 1.3 birds, parasitic and predatory insects and a small number. Species richness is not high, some small number of pests and natural enemies, do not form a fixed community, will not achieve sustained control of some pest role for pest and disease outbreaks can not be ignored another reason. Coupled with the irrational use of pesticides, which led to a vicious circle, both spraying pesticides to control pests but also kill the beneficial birds,[link widoczny dla zalogowanych], beneficial insects,[link widoczny dla zalogowanych], such a result and that pests are not going to curb their eco-systems, pest and disease outbreaks and to shorten the cycle harmful levels, Fan Si is also large, forcing the proliferation of pests, pesticide use again, so, again and again, the results of group trees lose vigor, pest and disease is still not effectively controlled. 2003 great place Drosicha Kuwana, a large area is a result of pesticide to kill pests also kill many beneficial insects, even the birds have retreated j homes, suffered great damage to the ecological balance of the system. 1.4 Environmental factors have led to the occurrence of pests and diseases with the development of tourism, the number of visitors increased, Trampling serious ground, soil compaction and high permeability is poor, the roots of old trees, breathing is inhibited. As the main reason is the weakness of ancient man-made pine stampede. Some potential weak orientalis in this environment is also increasingly vulnerable to pests and diseases. Such as the dual of Cooper's article shirt against beetles, it is the fatal weakness against Cooper, as strong prime arborvitae tree vigor is difficult to be invaded. The increase in human activities,[link widoczny dla zalogowanych], must also led to air and water pollution increase, seriously affecting the growth of trees, causing trees growing weak and vulnerable to pest damage. Since the invasion of alien pests and diseases, 1.5 modern urban green development in and around the temple are constantly planting some trees, flowers, landscape of the modern models have penetrated into the ancient building communities. The result of this has also brought some negative impact, that is not the original group of temple trees to be introduced pests and diseases. If Drosicha Kuwana calmly walked garden department because of some ornamental peach trees planted,[link widoczny dla zalogowanych], and gradually spread to the temple, causing the 2003 outbreak Drosicha Kuwana. The stick insect as the occurrence of the lawn, but also because after the laying of turf and introduced. The introduction of tree species in when it should be taken into account the negative impact from the concept of protecting groups of old trees, on the introduction of plant species should also increase awareness of quarantine pests and diseases slow. 2 2.1 enhanced integrated pest management of tree vigor strengthen routine maintenance, strengthening the management of water and fertilizer to improve the nutritional status of the tree, organic manure to increase the proportion of people, thin manure handling facilities. Facilities who can improve the soil structure and organic manure and fertilizer lasting. Of pine were added the amount of trace elements Fe, applied to improve the soil pH, chlorophyll synthesis to provide the necessary trace elements. Note that pruning, pest branches removed in time, to maintain forest health and reduce the overwintering insect population. Cultivation, weed and air and light, and enhance tree vigor, resistance to improve their own trees. 2.2 replanting of a pest plant species rich in small groups and with trees of different species of trees. As has planted tree, in Cypress, mulberry and other trees with stronger resistance to pests and diseases. Bungeana planting replacement of aging while also taking into account the dead pine, choose these species should not affect the overall landscape style of the temple premise, the temple and the surrounding green and the trees with a small group of the same species of trees, to avoid the several single outbreak caused by pests and diseases. 2.3 in the comprehensive management of pests and diseases, we must give priority to protection of birds, ladybugs and other beneficial organisms living environment and reduce the use of chemical pesticides and frequency. On the hazards of Sophora japonica Sophora japonica in recent years geometrid winter and spring, we used the approach of personnel digging pupae, select Sophora japonica hedges and trees near the pool excavation overwintering pupae, the effect is significant, continuous mining, calmly walked horses than 3 years now Won Wai Huai concentrated trail spraying twice annually, the temple of the ancient acacia trees are unnecessarily re-spraying of pesticides. The article on the shirt against the two arborvitae Hope, the whole tree from ten to only the individual potential applicator weak, there is adult emergence larvae L applicator of trees in early spring, both to avoid the birds, the breeding ladybirds , also used the dose reduced by 70%, well protected the environment. Prevention and treatment of arborvitae moth, the use of Ps a 15 �� type of frequency vibration-killing lamp to trap and kill adults, the effect is very good. 2.4 trees to improve the lives of the soil environment. Root absorption area landfill in the trees branches, leaves, may be appropriate to add a small amount of organic fertilizer or trace elements,[link widoczny dla zalogowanych], the tree flowers do not set boundaries of protection areas set aside the boundary to prohibit tourists stampede to maintain the permeability of root system, which will help root respiration, increased tree vigor, resistance to pest invasion. To prevent the invasion of exotic pests and diseases 2.5. The introduction of species to be considered, particular attention to whether the introduction of new pests, strict monitoring, once found, must be promptly removed, create a file, provide the basis for the prevention and management.
