摘要
通过磁性生物肥在玉米上的施用效果试验,可以看出施用磁性生物肥料,玉米植株生长健壮,叶色浓绿,但产量和收益明显低于施用化肥处理。土壤养分和土壤有益微生物数量变化不明显,土壤有机质增加较多,分别较玉米专用肥和空白对照增加15.46%和5.43%。说明生物有机肥对改善土壤环境、维持土壤有机质平衡有一定的积极作用。
The results of experiment of applying magnetic biology in corn indicated that in treatment of applying magnetic biological fertilizer, the corn plant growth was vigorous and healthy, color of leaves thick green, but yield and income was obviously lower than that of applying chemical fertilizer treatment. Soil nutrients and the number of beneficial microbes in soil was not changed obviously, whereas soil organic matter increased 15.46 percent and 5.43 percent compared with those applied special-purpose fertilizer and the control. Results showed that bio-organic fertilizer could improve soil environment and maintain balance of soil organic matter.
