BGF有机肥对马铃薯农药减量、土壤理化性状及产量的影响

本研究在内蒙古四子王旗东八号乡开展马铃薯种植试验,试验材料为马铃薯（荷兰7号）,重点监测马铃薯生长期间病虫害发生的相关指标,量化评估BGF有机肥在农药化肥减量方面的效果,适当分析其作用机制。 结果表明：施用 BGF 有机肥的土壤有机碳含量提高了 0.1～0.2 个百分点,氮和钾含量分别提高了 13.6%～15.9%、9.1%～13.6%,钙含量提高了 6.6%～18.3%,同时重金属离子砷和汞含量分别降低了 25.0%～30.9%、12.5%～25.0%,说明 BGF有机肥能提高土壤有机碳含量,促进营养元素的释放,降低金属离子活性。单株薯产量提高了 10.2%～15.6%,亩产量提高了12.6%～20.9%,商品薯率提高4.1%～7.1%,增产效果较为明显;从品质表现来看,干物质含量提高了 7.4%～33.8%,同时T3的淀粉含量提高了 29.6%。综合来看,以施用 200kg/亩 BGF 有机肥效果最佳。

Effects of BGF organic fertilizer on pesticide reduction, soil physical and chemical properties and yield of potato

This study carried out potato planting experiment in East No. 8 township of Siziwangqi, Inner Mongolia, The test material was potato The results showed that the content of soil organic carbon increased by 0.1 ~ 0.2 percentage points, the contents of nitrogen and potassium increased by 13.6% ~ 15.9%, 9.1% ~ 13.6% and the content of calcium increased respectively The content of arsenic and mercury decreased by 25.0% ~ 30.9% and 12.5% ~ 25.0% respectively, indicating that BGF organic fertilizer can improve the content of soil organic carbon, promote the release of nutrient elements and reduce the activity of metal ions. The yield per plant increased by 10.2% ~ 15.6%, the yield per mu increased by 12.6% ~ 20.9%, and the commercial potato rate increased by 4.1% ~ 7.1%; From the quality performance, the dry matter content increased by 7.4% ~ 33.8%, and the starch content of T3 increased by 29.6%. In general, the effect of applying 200kg / mu BGF organic fertilizer is the best.
