| 摘 要： | 为研究土层置换犁改良土壤后对不同层次土壤酶活性及土壤养分含量的影响，于大豆苗期、盛花期及成熟期对土壤过氧化氢酶、脲酶、蔗糖酶采用常规方法进行测定，并于大豆成熟期对土壤养分含量进行常规方法测定。结果表明，土层置换改变了土壤土体结构的同时对土壤中土壤酶产生了影响，土层置换区的不同层次土壤酶活性与对照区差异显著；土层置换区土壤养分含量随土层深度增加表现不同的变化趋势，与对照区各层次差异显著，土层置换有利于土壤养分含量在不同土层中的均匀分布；对照区随土层深度增加土壤碱解氮、有效磷含量呈下降趋势，土层置换区大豆产量为2245.5 kg/hm2与对照相比增产20.1%。土层置换可全面活化土壤养分，提高土壤酶活性，从而能够增加土壤活土层、提高土壤出水能力，对于提高土壤抗灾能力、提高作物产量具有重要作用。

| Abstract: | The objective of current study was to investigate the effects of soil layer replacement on soil enzyme and soil nutrient content of different layer. The catalase ,urease and invertase of soil at seeding stage, flowering stage and mature stage of soybean were determined, and the soil nutrient content were determined.at mature stage of soybean. The results showed that soil layer replacement changed the structure of soil, and had effect on the soil enzyme. The soil enzyme activity had significant differences between the different soil layer of soil layer replacement area and the control area; The soil nutrient content at soil layer replacement area showd that diferent change trend with the depth of soil incresaed, and there were significant differences compared with the control area. The soil layer replacement make against the soil nutrient content uniform distribution in different soil layers;
The abailable phosphorus and abailable potassium of the control area soil showd that downward trend with the depth of soil incresaed.The soybean yield of soil layer replacement was 2245.5 kg/hm2, it was higher 20.1% than contorl.. |
