生物有机肥对中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

将不同用量生物有机肥施入中度盐碱土中,研究其对土壤理化性质的影响。结果表明,生物有机肥可以改善中度盐碱土的pH值,有效缓解由于植物生长所造成的土壤养分的消耗。生物有机肥可在中度盐碱土中广泛使用,但在施用时应根据不同地区的土壤气候条件确定最佳的施肥量。

Microbial organic fertilizer was applied to saline-alkaline soil and the change of the soil fertility was analysized. The results indicated that the microbial organic fertilizer could markedly reduce pH value of the saline-alkaline soil,and alleviate the soil nutrient decrease efficiently caused by plant growth. Microbial organic fertilizer could be widely used in saline-alkaline soil. When using microbial organic fertilizer,the best quantity of fertilizer should be selected by different kinds of soil and climate conditions.
