不同种植年限下油茶产地土壤化学计量特征分析

Analysis of Soil Stoichiometric Characteristics of Camellia Oleifera in Different Planting Years

为了研究不同种植年限对福建山区油茶土壤化学计量特征的影响,对不同种植年限下油茶土壤主要化学性质及化学计量特征进行了系统研究。结果表明:不同种植年限下油茶产地土壤养分最优特征表现在2020年,2019年—2020年表现为逐渐增加的趋势。长期栽培油茶的土壤,常有进一步酸化的趋势。不同种植年限下生态化学计量特征变化不大,相差数值基本上比较接近。

In order to study the effects of different planting years on the stoichiometric characteristics of Camellia oleifera soil in Fujian Mountainous Area,the main chemical properties and stoichiometric characteristics of Camellia oleifera soil under different planting years were systematically studied.The results showed that the optimal characteristics of soil nutrients in different planting years of Camellia oleifera were in 2020,and gradually increased from 2019 to 2020.The soil of Camellia oleifera cultivated for a long time tends to be further acidified.Under different planting years,the ecological stoichiometric characteristics changed little,and the difference value was not big,basically close.
