摘要:
为改善滨海盐土质量,通过黄麻秸秆还田及施用有机肥对盐土的改良试验,研究不同施用量的秸秆与有机肥配施分别对土壤酶活性、微生物的影响。结果表明:以3 600 kg/hm2秸秆施用量分别与有机肥施用量为2 400、3 600 kg/hm2配施时对土壤生物性质改良效应较为明显,土壤脲酶分别比对照增加53 %和98 %、蔗糖酶增加700 %和825 %、过氧化氢酶增加49 %和65 %、磷酸酶增加99 %和161 %、土壤微生物数量增加了5.8、9.5倍,其中,真菌增幅较大,两种方式下分别增加55.1、90.8倍。说明秸秆与有机肥配施能明显提高滨海盐土酶活性,增加土壤微生物数量,增强土壤生物学活性,从而提高土壤肥力。
Abstract:
To improve the quality of the coastal solonchak, effects of both the jute straw and organic fertilizer on both the enzyme activity and microbial number in the coastal saline soil modified with the different level of both the jute straw and organic fertilizer were investigated. The results indicated that: the soil biological properties were obviously ameliorated when the jute straw was applied at the level of 3 600 kg/hm2 and organic fertilizer at the level of 2 400, 3 600 kg/hm2. Compared with the control, the urease activity was increased by 53 % and 98 %, invertase activity by 700 % and 825 %, hydrogen peroxidase activity by 49 % and 65 %, phosphatase activity by 99 % and 161 %, microbial number was increased by a factor of 6.8 and 10.5, fungi amount by a factor of 56.1 and 91.8, namely, relatively large increase amplitude. It is concluded that the application of jute straw and organic fertilizer obviously increased those enzymes activities and microbial number, enhanced soil biological activity, and improved soil fertility.
