摘要

为探究施用金针菇菌渣对川西北高寒沙化土地植被、土壤有机碳和土壤酶活性的影响，通过田间试验和土壤样品采集与化验，研究了不同菌渣量处理下川西北高寒沙地植被、土壤理化性质及酶活性变化特征。研究结果表明，15 kg/m2菌渣混施（F4）、10 kg/m2菌渣混施（F3）、5 kg/m2菌渣混施（F1）处理下地表植被盖度、高度、生物量、土壤含水量、有机碳及酶活性显著高于对照（CK），土壤容重显著低于CK。F4处理下，植被盖度、高度、生物量、土壤含水量、有机碳、纤维素酶、淀粉酶、蔗糖酶和多酚氧化酶活性分别增加了272.20%，144.51%，228.85%，616.46%，93.25%，135.90%，129.22%，154.41%，99.88%，115.03%；土壤容重降低了39.04%。说明菌渣与土壤混施对于川西北高寒沙化草地植被恢复、土壤理化性质改善和土壤酶活性提高具有显著效果，且随着菌渣施用量的增加作用效果增强。F2处理下土壤有机碳、纤维素酶、淀粉酶、蔗糖酶和多酚氧化酶活性与CK相比差异未达显著水平，但显著低于F1、F3、F4处理，表明菌渣地表覆盖方式施用效果不及混合施入土壤方式。相关性分析结果表明，有机碳、地下生物量、纤维素酶、淀粉酶、蔗糖酶和多酚氧化酶活性两两之间极显著相关（P＜0.01）。

Abstract

In order to reveal the effects of edible fungus residue on vegetation

soil organic carbon and enzyme activities of sandy soil

sandy soil was sampled in the northwest Sichuan as research object by five point sampling method. The results showed that the treatment of mixing 5 kg/m2 edible fungus residue in soil (F1)

mixing 10 kg/m2 edible fungus residue in soil (F3) and mixing 15 kg/m2 edible fungus residue in soil (F4) could significantly increase vegetation coverage and height

biomass

soil water content

organic carbon and enzyme activities

and decrease the soil bulk density. Compared with CK

the treatment of F4 increased vegetation coverage and height

biomass

soil water content

organic carbon and enzyme activities by 272.20%

144.51%

228.85%

616.46%

93.25%

135.90%

129.22%

154.41%

99.88%

115.03% and decreased the soil bulk density by 39.04%. It indicated that the mixing of edible fungus residue and soil had a remarkable effect on vegetation

soil physicochemical properties and enzyme activities. The treatment of F2 could increase soil organic carbon

cellulase

amylase

invertase and polyphenol oxidase activity compared with the CK

but it was significantly lower than F1

F3 and F4. This result indicated that the effect of cover the soil was better than that of edible fungus residue mixed application. Correlation analysis showed that the SOC

below biomass and enzymes activities were obviously positive correlation（P<0.01）.
