生物有机肥对轻度盐碱土理化性质影响的研究

Improving Effect of Microbial Organic Fertilizer on Physical and Chemical Properties of Saline-alkaline Soil

目的:研究施用生物有机肥改善盐碱土。方法:将生物有机肥施入轻度盐碱土中,研究其对土壤理化性质的影响。结果:生物有机肥可以改善轻度盐碱土pH值,有效缓解由于植物生长所造成的土壤养分的消耗。结论:生物有机肥可在轻度盐碱土中广泛使用,在施用时应根据不同地区的土壤气候条件确定最佳施肥量。

Objective： Soil saline- alkaline has become one of the most important problems in the world. How to improve saline - alkaline soil turns to a momentous research aspect.Methods： The experiment was performed by application microbial organic fertilizer to light saline - alkaline soil and analysis of the change of the soil fertility.Results： It indicated that the microbial organic fertilizer could markedly reduce pH value of the light saline- alkaline soil,and alleviate the soil nutrient decrease efficiently caused by plant growth. Conclusion： microbial organic fertilizer can be widely used in Saline - alkaline Soil. When using microbial organic fertilizer, the best quantity of fertilizer should be torched by different kinds of soil and climate conditions.
