化肥减量配施腐植酸生物肥对土壤性质的影响

目前,植物生存所必备的重要环境因素——土壤,其质量逐年呈现下降趋势。腐植酸类材料技术的应用在改良土壤理化性质和提高肥力上有明显效果。文章以雷波脐橙为研究对象,进行科学腐植酸肥部分替代普通化肥的种植试验。研究表明,相较于单施化肥处理组,添加腐植酸生物肥的处理组中土壤养分含量均有所提升,究其原因主要是化肥配施腐植酸生物肥一方面可提供脐橙生长所需要的速效养分,另一方面可满足土壤中微生物群落的养分需求,土壤中有效养分增多,进一步使土壤肥力提升。

At present,the quality of soil,which is an important environment factor for plants,is declining year by year.The application of humic acid material technology has obvious effect on improving soil physical and chemical properties and improving soil fertility.In this paper,taking Leibo navel orange as the research object,the planting experiment of scientific humic acid fertilizer instead of common chemical fertilizer was carried out.This study shows that,compared with the single application of chemical fertilizer,the content of soil nutrients in the treatment group with humic acid biological fertilizer increased.The main reason is that the combination of chemical fertilizer and humic acid biological fertilizer can provide the available nutrients needed for navel orange growth on the one hand.On the other hand,it can meet the nutrient needs of the microbial community in the soil,increase the available nutrients in the soil,and further improve the soil fertility.
