摘要

为阐明三峡库区坡耕地典型香榧套种模式对土壤碳(C)、氮(N)、磷(P)含量及其生态化学计量特征的影响

在重庆市云阳县宝坪镇香榧种植基地内

选取香榧纯林(TG)、香榧-黄精(TGP)、香榧-大豆(TGG)3种套种模式为研究对象

分析不同模式及土层深度下土壤C、N、P含量及其生态化学计量特征。结果表明:不同模式的土壤C含量无显著差异

N、P含量均表现为TGG(0.80

0.53 g/kg)>TGP(0.71

0.40 g/kg)>TG(0.56

0.39 g/kg)

且与TG相比

TGG的N、P含量分别显著提高42.9%

35.9%。土壤C、N主要富集在0—10 cm土层

而P主要集中在10—20 cm土层。3种模式的土壤C∶N、C∶P、N∶P分别为8.39~10.73

31.63~45.22

3.25~5.61

均低于全国平均值(14.4

136.0

9.3)。N∶P<10

表明N为研究区限制性养分。相关性分析结果表明

土壤pH、容重和总孔隙度也是影响土壤C、N、P含量及其生态化学计量的重要指标。香榧套种模式有利于土壤养分的积累

TGG的C、N、P含量高于TGP和TG

有较好的培肥效果。

Abstract

To explore the effects of typical Torreya grandis intercropping systems on soil carbon (C)

nitrogen (N)

and phosphorus (P) content and their stoichiometric characteristics on sloping farmland in the Three Gorges Reservoir Area

three typical intercropping systems

T. grandis (TG)

T. grandis-Polygonatum sibiricum (TGP)

and T. grandis-Glycine max (TGG)

were selected in the T. grandis planting bases located in Baoping Town

Yunyang County

Chongqing. The contents of C

P in soil and their ecological stoichiometric characteristics under different models and soil depths were analyzed. The results showed that there was no significant difference in soil C content among different systems. Both N and P contents followed the order of TGG (0.80

0.53 g/kg)>TGP (0.71

0.40 g/kg)>TG (0.56

0.39 g/kg)

and compared with TG

N and P contents of TGG were significantly higher by 42.9% and 35.9%

respectively. Soil C and N mainly concentrated in the 0-10 cm soil layer

while P mainly concentrated in the 10-20 cm soil layer. Soil C∶N

C∶P and N∶P under the three systems was 8.39~10.73

31.63~45.22 and 3.25~5.61

respectively

which were all lower than the national average values (14.4

136.0

9.3). And the N∶P ratio was less than 10

indicating that N was the limiting nutrient in the study area. The results of the correlation analysis showed that soil pH

bulk density and total porosity were also important indicators affecting soil C

and P contents and their ecological stoichiometry. T. grandis intercropping systems significantly enhanced the accumulation of soil nutrients. The content of C

N and P of TGG was higher than that of TGP and TG

and TGG showed better fertilizer cultivation effect.
