杨梅不同栽培模式效益评价

Evaluation on Effect of Different Cultivation Patterns of Chinese Bayberry

杨梅在常规栽培模式下,栽植密度为330 ～ 400株/hm2,第4年开始少量投入产出,第8年开始获取纯利润,第13年产值达8.0万元/hm2;投资年平均效益系数为0.26元,年平均投入产出比1∶3.43.杨梅-茶-桃混交林模式,初植密度为杨梅200株/hm2,茶18 000株/hm2,桃600株/ hm2,造林后第3年少量产出,第5年即可获取纯利润,投资回收期比纯林栽培模式缩短3a,第13年产值达10.5万元/hm2;投资年平均效益系数为0.35元,年平均投入产出比1∶4.56.可见,与纯林相比,混交林模式具有投入产出早、投本少、投资回收快、投资效益系数高等特点.混交林尚有较好的社会效益和生态效益.

With the density of 330~400 tree/hm2, Chinese bayberry forest has a few products in the 4th year. From the 8th year, it can gain the net-profit, and the annual output value reaches 80 thousands yuan RMB/ hm2 in the 13th year. The annual rate of input/output is 1:10. In the mixed forest of Chinese bayberry-tea-peach, the density of Chinese bayberry is 200 tree/ hm2, tea 18 000 tree/ hm2, peach 600 tree/ hm2. The mixed forest has a few products in the 3rd year and gains the net-profit in the 5th year. The output value reaches 105 thousands yuan/ hm2 in the 13th year. The rate of input/output tops 1:4.56. As the result, mixed forest has better economic and ecological benefits.
