摘要: 以偃师市葡萄保护区种植5、8、13、20 a的葡萄园土壤为研究对象,测定0~100 cm 土层土壤C、N、P含量及微生物量C、N、P(MBC、MBN、MBP)含量,并分析其生态化学计量特征,以期为葡萄园的持续经营管理提供科学依据。结果表明:土壤C、N、P含量随种植年限增加而明显增加,种植20 a土壤分别较种植5 a增加了20.38%、64.91%、105.26%;土壤MBC、MBN、MBP含量同样随种植年限的增加而增加,种植20 a土壤分别较种植5 a增加了205.61%、191.86%、81.56%。土壤C∶N随着土层深度增加总体呈上升趋势,这种趋势随着种植年限的增加逐渐减弱,当种植年限为20 a时C∶N趋于平稳;土壤C∶P(种植13 a除外)和N∶P(种植8 a除外)随着土层深度增加总体呈先上升后下降的趋势。种植年限与土壤C、N、P、MBC、MBN、MBP含量及其生态化学计量比之间总体上呈显著或极显著相关。

Abstract: The soil C,N,P and microbial biomass C,N,P(MBC,MBN,MBP)contents in 0—100 cm soil layer were measured in vineyards planted for 5,8,13 and 20 years in Yanshi City grape reserve,and their ecological stoichiometric characteristics were analyzed,so as to provide scientific basis for the sustainable management of the vineyards. The results showed that the contents of C,N and P in soil increased obviously with the increase of planting years. The contents of C,N and P in soil with grape planted for 20 years increased by 20. 38%,64. 91% and 105. 26% respectively compared with the soil with grape planted for 5 years. The contents of MBC,MBN and MBP in soil also increased with the increase of planting years. The contents of MBC,MBN and MBP in soil with grape planted for 20 years increased by 205. 61%,191. 86% and 81. 56% respectively compared with the soil with grape planted for 5 years. Soil C∶N increased with the increase of soil depth,the increase trend weakened with the increase of planting years,when the grape was planted for 20 years,C∶N tended to be stable. Overall,soil C∶P(except the soil with grape planted for 13 years)and N∶P(except the soil with grape planted for 8 years)increased firstly and then decreased with the increase of soil depth. There were significant or extremely significant correlations between planting years and soil C,N,P,MBC,MBN,MBP contents and their ecological stoichiometry ratios.
