通过调查浙江省常山等四县及湖北松滋县不同立地条件、不同经营水平和种植密度的14块油茶丰产林分,用统计分析法分析了叶面积指数与产量、密度、群体内光强分布、土壤养分状况的关系,得出了叶面积指数与净光合经济生产率的关系式为LnY=3.041LAI-4.487(P>0.05);叶面积指数与群体内相对光强之间的关系为InI_/I_0%=2.858-0.415/LAI(P>0.01)。提出了低丘红壤类型的油茶林最适密度为70—90株/亩。初步确定油茶林的最适叶面积指数是4.00—5.22。
Through the investigation of 14 high-yield stands of Camellia oleifera with different site conditions, different management levels and planting densities in four counties, such as Changshan in Zhejiang Province and Songzi County in Hubei Province, the leaf area index, yield, density and light intensity distribution in the population were analyzed by statistical analysis The relationship between leaf area index and net photosynthesis economic productivity was LnY = 3.041LAI-4.487 (P> 0.05). The relationship between leaf area index and relative light intensity in the population was InI_ / I_0% = 2.858-0.415 / LAI (P> 0.01). The optimal density of Camellia oleifera forest with the red soil type of low hill is 70-90 plants / mu. The optimal leaf area index of Camellia oleifera forest is 4.00-5.22.
