中文摘要 | 为了探明长期施用有机肥对旱地土壤酶活性的影响,为旱地土壤改良技术体系的建立提供依据。在宁南旱区进行3 a有机肥定位施用试验,设置3个有机肥施用量水平:30 000 kg/hm~2 (L)、60 000 kg/hm~2 (M)和90 000 kg/hm~2 (G),以不施有机肥作为对照(CK)。结果表明,长期施用有机肥对0~20 cm土层土壤脲酶、磷酸酶、蔗糖酶影响较为显著,特别是高量有机肥处理,3 a较对照平均提高幅度分别为127.7%、26.1%和19.5%;各有机肥处理0~20 cm土层土壤脲酶、磷酸酶活性大小顺序基本为G≥M>L≥CK,G和M处理效果最显著,3 a较对照分别提高(P<0.05)32.5%~197.2%和16.7%~34.8%;各有机肥处理过氧化氢酶变化规律不明显,基本维持在8.07~9.48 U_4。说明,旱地施有机肥对提高一些土壤酶活性有显著效果。 |
英文摘要 | Effect of long-term organic fertilization on soil enzyme activity in arid area was studied in the paper, so as to provide technical system for soil improvement in semi-arid areas of southern Ningxia.The experiment of long-term located organic fertilization had been done in arid area of Ningnan for 3 years. With unorganic fertilization as CK, 3 different treatments of organic fertilizer application (G:90 000 kg/hm~2, M:60 000 kg/hm~2 and L:30 000 kg/hm~2),the result showed that urease, phosphatase and invertase activities under G treatment more significantly increased than CK in 0-20 cm soil layer, the average increase of three years were 127.7%,26.1% and 19.5%, respectively. The order of urease, phosphatase in 0-20 cm soil layer is: G≥M>L≥CK, and G and M treatments had the most significant effects compared with CK, the increasing range of the two fertilization treatments were 32.5%-197.2% and 16.7%-34.8%,respectively,while there were no obviously changes in catalase activity with different organic fertilization treatments, the contents were mostly between 8.07 and 9.48 U_4. In conclusion, application of organic fertilizer in semi-arid areas plays an active role in improving some enzyme activities significantly. |
