摘要
东三省是玉米主要产区,土壤肥力退化给玉米种植带来一定的威胁,而土壤微生物活动可以对土壤中的有机质进行分解和转化,提高玉米产量。文章选择东北平原中部公主岭为试验地,分析不同微生物活动对玉米产量的影响,得出添加蚯蚓粪的土地玉米产量比只加入优化施肥玉米产量提高6.8%。
The three eastern provinces are the main corn producing areas. The degradation of soil fertility brings a certain threat to corn planting. Soil microbial activities can decompose and transform the organic matter in the soil, and improve the corn yield. In this paper, Gongzhuling in the middle of the Northeast Plain was selected as the experimental site to analyze the effect of different microbial activities on the yield of corn. It was concluded that the yield of corn in the land with earthworm manure was 6.8% higher than that only with optimized fertilization.
