摘要

为探究不同绿肥品种翻压条件下晋南旱地麦田土壤团聚体稳定性以及有机碳(SOC)和全氮(TN)在不同粒径团聚体的分布特征

深入了解不同种类绿肥的增碳保氮机制。已连续3年(2018—2021年)不同绿肥品种(对照休闲、大豆、绿豆、油葵、玉米)翻压还田后冬小麦收获期0-10

10-20

20-30 cm土壤为研究对象

采用湿筛法进行土壤粒径分级

并分析粗大团聚体(>2 mm)、细大团聚体(0.25~2 mm)、微团聚体(0.053~0.25 mm)和粉黏粒组分(<0.053 mm)中SOC和TN含量

测算团聚体的构成与稳定性(R0.25

>0.25 mm团聚体含量;MWD

平均重量直径;GMD

几何平均直径)

并测定各粒径团聚体SOC和TN及其对土壤总有机碳和总氮的贡献率。结果表明:不同绿肥处理下旱地麦田土壤团聚体质量占比均以细大团聚体0.25~2 mm为主(占22.77%~39.71%)。复播绿肥显著增加0-30 cm土层>2 mm粒径团聚体质量占比

以大豆绿肥增加最明显

0.25~2

0.053~0.25 mm粒径团聚体质量占比降低

对<0.053 mm粉黏粒的影响不明显;大豆绿肥对各土层R0.25、MWD和GMD值提高作用明显。大豆和玉米对0-30 cm各土层土壤总有机碳含量具有显著提高作用

分别提高27.83%和25.71%。大豆绿肥进一步提高土壤各粒径团聚体有机碳含量。复播绿肥降低土壤全氮含量

大豆绿肥处理的降低程度最小

且对<0.053 mm粉黏粒全氮含量具有增加作用。0.25~2

>2 mm大团聚体对0-10 cm土层土壤有机碳和全氮的贡献率最高;复播绿肥提升土壤碳氮比(平均21.39)

较对照休闲(平均13.71)提高7.68

其中玉米提升效果最佳

大豆次之。综合土壤增碳固氮效果

连续3年翻压大豆绿肥可有效提高旱地麦田土壤团聚体稳定性

提升土壤肥力。

Abstract

In order to investigate the stability of soil aggregates and the distribution characteristics of organic carbon (SOC) and total nitrogen (TN) aggregates in different particle sizes under different green manures application in dryland wheat fields in southern of Shanxi Province

and further understand the mechanism of carbon and nitrogen conservation of different green manures. Topsoil samples of 0-10

10-20 and 20-30 cm after three consecutive years (2018—2021) during the winter wheat harvest period were collected under different green manure treatments (control

soybean

mung bean

sunflower

maize). Wet sieve method was used to classify the soil particle size. The contents of SOC and TN in coarse macroaggregates (>2 mm)

fine macroaggregates (0.25~2 mm)

microaggregates (0.053~0.25 mm) and silt+clay (<0.053 mm)

and the stability of aggregates (R0.25

aggregates mass fractions of >0.25 mm; MWD

mean weight diameter; GMD

geometric mean diameter) were measured. The contribution rates of aggregate SOC and TN to soil total organic carbon and total nitrogen of different particle sizes were measured. The results showed that the proportion of soil aggregate mass of fine and large aggregates was mainly 0.25~2 mm (22.77%~39.71%) under different green manure treatments. Aggregates mass fractions of >2 mm in 0-30 cm soil layer was significantly increased under green manure application

especially under soybean green manure

while the mass proportion of 0.25~2 mm and 0.053~0.25 mm particle size decreased

the mass proportion of <0.053 mm showed no obvious. Soybean green manure significantly increased R0.25

MWD and GMD values in all soil layers. Soybean and maize significantly increased the soil total organic carbon content in 0-30 cm soil layers by 27.83% and 25.71%

respectively. Soybean green manure further increased the content of SOC in soil aggregates of different particle sizes. Applying green manure reduced the soil total nitrogen content

soybean green fertilizer treatment had the smallest reduction degree

and had an effect on increasing the total nitrogen content of <0.053 mm silt clay. The contribution rates of soil organic carbon and total nitrogen in 0-10 cm soil layer were the highest in large aggregates of 0.25~2 and >2 mm. Green manure (mean 21.39) application increased the soil C/N ratio by 7.68 compared with the control fallow (mean 13.71)

among which maize had the best lifting effect

followed by soybean. Combined with the effect of soil carbon and preserve nitrogen in dryland wheat fields

soybean green manure for three consecutive years can effectively improve the stability of soil aggregates and soil fertility.
