培育胶合板材二种密度分布对间作年限和收益大小的影响

通过不同栽植密度分布2×8(m)和2×2×14(m),连续进行间作(年限)和收益大小的研究.结果表明,2×2×14(m)是窄冠幅杨树品种培育胶合板材的理想密度分布,农作物可间作6年,牧草互间作5年.总间作收益达52 742.4元/hm2.林地农林产品总收入和利润均可达到和超过单纯农业的收入且生态效益显著.

Study on Intercropping Years and Benefit under Two types of Density Distribution in Cultrual Veneer Log

By the experiment in had a study of ontinuous intercropping years and income in two types planting density (2×8)m and (2×2×14)m.The result from the woodland of the type (2×2×14)m cedonstrated that ideal density in narrow crown of ploar strain for cultural veneerlog crop can out vate for 6 years and grazing for 5 years.Total intercropping income is to 52 742.4 yuan hectatr.Total profit and income of rarm and forest products is more than only farmland.In the woodland,it was gotten the aim of fund from crop and then ivested.he fund in forest growth and the woodland was increased its benefit.At the same time.it made a great deal of ecological benefit.
