摘要
【目的】为明确抚育间伐和施肥综合改培技术措施对江西大岗山地区樟树成龄低质人工林生长、蓄积和经济效益的影响。【方法】课题组在安福县明月山林场泰山分场设置试验林,对樟树人工林实施综合改培措施与未采取经营措施的进行对照,分析效果效应。【结果】综合改培措施实施1年后,樟树径向生长量比对照提高了33.33%,单位面积蓄积生长量比对照提高了31.71%。年均净效益增长为12782元/(hm^(2)·a),比对照提高了2644元/(hm^(2)·a),投入产出比1∶4.81。【结论】樟树低质人工林采用综合改培措施,效果明显,并可获得较高的经济效益,适合生产上推广。
[Objective]To clarify the effects of intermittent cutting and comprehensive fertilization improved measure on mature and low quality camphor tree plantation’s growth,volume of timber and economic benefits in Dagang Mountain,Jiangxi Province.[Method]The research team set up experimental forests in the Taishan branch of Mingyue Mountain in Anfu County,and compared the effect of camphor tree plantations with comprehensive fertilization improved measure to those without management measures.[Results]A year’s implementation of the comprehensive cultivation measures,the radial growth of the camphor tree increased by 33.33%,and the accumulative growth of the single plant increased by 31.71%than that of the control.Average annual economic benefit was 12782 yuan/(hm^(2)·a)respectively,increased 2644 yuan/(hm^(2)·a)than that of the control,and the inputoutput ratio was 1:4.81.[Conclusion]The camphor tree plantation with comprehensive fertilization improved measure has obvious effects and higher economic benefits,which is suitable for production and promotion.
