碳汇林套种五指毛桃的林下经济经营模式研究——以广东省九连山林场五指毛桃特色经济林基地为例

Study on Understory Economic Model of Interplanting Ficus hirta in Carbon Sink Forest—Taking Ficus hirta Characteristic Economic Forest in Jiulianshan Forest Farm of Guangdong Province as an Example

文章在广东省九连山林场开展碳汇林套种五指毛桃Ficus hirta的林下经济模式研究,利用双因素方差分析法,从坡位、密度以及坡位和密度的交互作用3个因素来研究其对地径、苗高、冠幅、根长和根重的影响。结果表明:不同坡位对五指毛桃地径、冠幅、根长和根重产生显著影响;不同密度对五指毛桃地径、冠幅、根长和根重产生显著影响;不同坡位与密度的交互作用对五指毛桃的地径、苗高、冠幅、根长和根重均产生极显著影响;五指毛桃地径和苗高长势最佳的是位于中坡的密度为6255和3120株/hm²的植物样本;冠幅长势最佳的是位于上坡和中坡的密度为3120株/hm²的植物样本;地下部分最有优势的是为位于上坡的密度为2760株/hm²的植物样本。

In this paper,Ficus hirta was studied as an understory economic model,which was in Jiulianshan forest farm of Guangdong Province.By using the two-way analysis of variance,through the three effects of slope position,density and the interaction of slope position and density to study its effects on ground diameter,seedling height,crown width,root length and root weight.The results showed that different slope positions had significant effects on ground diameter,crown width,root length and root weight of F.hirta.Different densities had significant effect on the ground diameter,crown width,root length and root weight of F.hirta.The interaction of different slope positions and density had a very significant effect on the ground diameter,seedling height,crown width,root length and root weight of F.hirta.The best ground diameter and seedling height of F.hirta were located on the middle slope with density of 6255 plants/hm2 and 3120 plants/hm2.The best crown width of F.hirta were located on the upper and middle slopes with density of 3120 plants/hm2.The best underground growth of F.hirta were located on the upper slope with density of 2760 plants/hm2.
