摘要
[目的]为环保酵素对土壤钾素的改良提供科学依据。[方法]设4个不同浓度梯度（1∶250、1∶500、1∶750、1∶1000）的环保酵素液处理，施浇于已施加化肥及农药20余年的耕作土壤，通过8周的试验，研究不同浓度环保酵素液对土壤钾素的改良效果。[结果]1∶250、1∶500和1∶750环保酵素处理的土壤速效钾含量均有所增加，且1∶750处理的土壤速效钾增加较为明显，增幅达6．06％。但在整个试验中，全钾含量的增幅不明显，反而有下降趋势。[结论]环保酵素对土壤有改良效果，可提高土壤质量，以持续施浇1∶750环保酵素的改良效果最为明显。
Abstract
Objective] To study the improvement effect of soil potassium while using garbage enzyme.[Method] Within the experimental time of eight weeks, four groups of different concentration gradient(1∶250, 1∶500, 1∶750, 1∶1 000) of garbage enzyme liquid was used to sprinkle the farming soil which has been used fertilizers and pesticides more than 20 years, the improvement effects of different concentration garbage enzyme on soil potassium were studied.[Result] The available potassium content were all increased by using 1∶250, 1∶500, 1∶750 garbage enzyme, especially for 1∶750, reached 6.06%.In the whole experiment, the increase of total potassium was not obvious, but there was a downward trend.[Conclusion] Garbage enzyme can improve soil quality, the improvement effect by watering soil with concentration of 1∶750 garbage enzyme continuously is most obvious.
