生物有机肥对土壤性质及水稻产量的影响

Effects of Bio-organic Fertilizer on Soil Properties and Rice Yield

以嘉博文生物有机肥为材料,在十堰市郧阳区3个不同乡镇进行试验,探究生物有机肥对土壤性质及水稻产量的影响。结果表明,施用生物有机肥可有效提高土壤有机质、全氮、速效钾、缓效钾、有效磷的含量,与施用前相比,分别提升5.16%、5.56%、24.61%、1.07%、16.70%,土壤pH值变化不大且维持在中性左右;水稻产量较常规施肥处理也有一定程度提高。

Taking Jiabowen bio-organic fertilizer as material,experiments were carried out in three different townships in Yunyang District of Shiyan City to explore the effects of bio-organic fertilizer on soil properties and rice yield.The results showed that the application of bio-organic fertilizer could effectively increase the contents of soil organic matter,total nitrogen,available potassium,slow-acting potassium and available phosphorus,which increased by 5.16%,5.56%,24.61%,1.07% and 16.70% respectively,with little change in soil pH value and remained neutral.The rice yield also increased to a certain extent compared with conventional fertilization treatment.
