Research On Ecology Management Of Carya Cathayensis In Lin'an County

Hickory(Carya cathayensis)is one of Lin'an famous nuts,it's farmer's main economic income in major production area such as Daoshi.With the economic benefits improved,in pursuit of maximum benefit and the convenience of piking,they abuse of chemical fertilizers,pesticide,herbicides and remove all shrubs and weeds away.Which lead to be pure forests and ecological environment is deteriorating.Such as soil erosion,water storage ability,not resistant to drought,plant diseases and insect pests.These have seriously restricted the pecan industry in sustainable development so ecological environment is urgent.Luckily,under the promotion of technical personnel.In view of the existing problems in the traditional management model,proposed by the scientific and technical personnel pecan of sustainable ecological management model.This paper had mainly field investigation and questionnaire survey whit Daoshi,through the research to know that the operate model of hickory is mainly composed of the ecological model and the traditional model,but traditional model leads to ecological environment of pecan forest worse and worse,and the frequent occurrence of plant diseases and insect pests,pecan quality also falling.The economic effect of ecological management model is not significant in the short term,but with promoting tthis model,the author found that compareing with the traditional management model,the ecological management model will increase the pecan forest biodiversity;and higher quality of the nuts.Implementation of ecological management is advantageous to sustainable development of pecans in Daoshi township.But based on the low degree of education of foresters and the pursuit of maximum interests that tend to choosing the traditional management model,and ecological management model is complementary.In the process of rapid development of pecan industry in lin'an,Woodland finely seriously,has to pose a great threat to sustained and healthy development of the pecan industry in lin'an.Base on the above conclusion,and puts forward relevant policy Suggestions.Mainly includes the following Suggestions:(1)the government should strengthen the propaganda education,improve the cognitive level of ecology management model of pecans forest;(2)researching and developing management and technology is not enough,forestry scientific research personnel should speed up technology research and developed ecological management model;(3)do not pay enough attention to security,the government should give certain funding and support of foresters.
