盐生植物根际对土壤中微生物数量和酶活性的影响

Effect of the Halophytes Rhizosphere on the Amount of Microorganism and the Enzyme Activity in Soil

选择滨海盐碱地为研究对象,通过实验就盐生植物根际对土壤中微生物的数量和酶活性的影响进行了初步研究.实验结果表明,盐生植物种植后,根际土壤的微生物数量比非根际土壤明显增加,酶活性也有不同程度的提高.植物根系越发达,土壤中微生物的数量越多,土壤酶的活性也越高.为盐渍化土壤的植物修复提供了理论数据,具有一定的现实意义.

Choosing the Binhai saline-alkali soil as the research object, the effect of the halophytes rhizosphere on the amount of microorganism and the activities of enzymes in soil has conducted the preliminary study through the experiment. The experimental results indicated that, the amount of microorganism in the halophytes rhizosphere has an obvious increase than the non-rhizosphere soil after planting the halophytes and the ac tivities of soil enzymes also has an improvement in various degrees. With the development of the the plant root system, the amount of the microorganism in the soil becomes greater, and the activity of soil enzyme becomes higher. The research which offers the theory data for the restoration of saline land through the planting of halo- phytes has the certain practical significance.
