Abstract:Objective]The purpose of this project was to determine regeneration age and provide theoretical basis for the poplar regeneration of Hetian farmland shelterbelt based on our investigation of Hetian farmland shelterbelt growing states and cutting situation.Method]According to the growth data of different age Xinjiang poplars in Hetian County and Moyu County,we choose the Logistic method which is a common tree growth mathematical prediction model as the growth model of tree high and tree diameter,and determine the maturity ages of largest volume,technology,protection and economy of shelter forest belt for farmland. Result]According to the comprehensive analysis of the maturity ages of largest volume,technology, protection and economy of shelter forest belt for farmland,we determined that the reasonable poplar regeneration age is 23 to 28 years.Conclusion]We determine the poplar regeneration age of farmland shelterbelt was detennined and theoretical basis for the scientific management and update,and sustainable utilization of fannland shelterbelt was provided.
Keywords:oasis farm shelter belt  poplar  regeneration age  growth model
