摘要

为探讨不同覆盖物对城郊农业区葡萄园土壤呼吸及水热环境影响,设置对照 CK (露地),种植酢浆草、白三叶
草,覆盖黑膜、白膜 5 个处理,监测生长—生产期土壤呼吸、水热环境,然后分析了其响应关系。结果表明:( 1 ) 4 种不
同覆盖处理下相比露地( CK )显著提高了葡萄园土壤呼吸速率(
p <0. 05 ),呼吸速率总体表现为:白三叶 > 黑膜 > 白
膜 > 酢浆草。各处理土壤呼吸速率变化峰值均出现在8月份;( 2 ) 4种不同覆盖处理下葡萄园土壤水分在不同时期呈
现出较为明显的剖面垂直分异特征,各处理相比露地( CK )表现出明显的土壤水分保持能力,林下覆膜(黑膜、白膜)相
比林下生草(酢浆草、白三叶)表层持水保水能力表现突出,林下覆膜处理(黑膜、白膜)平均温度均高于 CK (露地),而
林下生草覆盖处理(酢浆草、白三叶)平均温度均低于 CK ,林下覆膜处理增温效果整体强于林下生草覆盖处理。黑膜
的增温效果相对较强,在维持土壤温度稳定也要优于其他处理,而露地维持温度稳定相对最差;( 3 )林下覆膜模式土
壤呼吸与土壤水分呈现显著二次函数关系(
p <0. 05 ),而林下生草模式土壤呼吸与土壤水分呈现指数函数关系( p <
0. 05 ),各处理土壤温度( 5cm )与土壤呼吸速率呈现指数函数关系,且各处理温度敏感系数表现为:黑膜 >CK (露
地) > 白膜 > 白三叶 > 酢浆草。从节碳减排、涵养水源角度出发,酢浆草与黑膜是较为适宜的覆盖模式;但如果进一步
考虑减少环境污染、提高植物生产碳源,保持城郊农业高效可持续发展,酢浆草与白三叶草覆盖模式,更适宜于新型
城郊农业生产。

其他摘要

 To explore the effects of different mulches on the soil respiration and hydrothermal environment of
orchards in urban vineyards , five filed treatments including CK ( open field ), planting Oxalis corniculata L.
and Trifolium 
repens L.
, covering
with black film and white film were designed , soil respiration and hydro -
thermal environment during growth - production period were monitored , and the response relationship
between them were analyzed.The results showed that :( 1 ) compared with bare ground surface ( CK ), the
soil respiration rate of vineyards under four different mulches significantly increased ( p <0.05 ), and the
respiration rate of vineyards was as follows : Trifolium repens L.>black film>white film> Oxalis cornicu -lata L.
; the peak soil respiration rate in each treatment occurred in August ;(
2 ) the soil moisture of the vine -
yards under 4different mulches and CK showed obvious vertical cross - section characteristics at different peri -
ods ; the soil under 4different mulches had significant water conservation capacity , film mulch ( black film ,
white film ) showed stronger water retention capacity than grass mulch ( Oxalis corniculata L.
, Trifolium
repens L.
); the average temperature of mulching
treatment ( black film , white film ) was higher than that of
CK ( open field ), while the average temperature of grass planting treatment ( Oxalis corniculata L.
, Trifolium
repens L.
) was lower than that of CK , effect of rasing
soil temperature in mulching treatment was stronger
than grass planting treatment ; black film treatment had a relatively
strong effect of rasing
soil temperature ,
and it was better than other treatments in maintaining soil temperature stability ;(
3 ) soil respiration and soil
moisture showed a significant quadratic function relationship in vineyards under film mulch ( p <0.
05 ), while
soil respiration and soil moisture showed an exponential function relationship in vineyards under grass mulch

p <0. 05 ); the soil temperature ( 5cm ) of all treatment had an exponential function relationship with the
soil respiration , and the temperature sensitivity coefficient ( Q 10 ) of each treatment was showed as follows :
black film>CK ( open field ) >white film> Trifolium repens L.> Oxalis corniculata L..From the perspec -
tive of carbon reduction and water conservation , Oxalis corniculata L.mulch and black film mulch are more
suitable mulch ; however , if further consideration is given to reducing environmental pollution and maintai -
ning
sustainable development of suburban agriculture , Oxalis corniculata L.mulch is much more suitable for
new urban agricultural production rather than other three types of mulch patterns.
