| 摘 要： | 通过控释肥养分释放试验和烤烟盆栽试验,研究了控释肥料对植烟土壤供肥特性、烟株伤流液和烤烟根系活力的影响.结果表明:施用控释肥提高了土壤养分含量及其空间有效性;提高了土壤真溶液的钾含量,烟株旺长期土壤真溶液的养分含量最高;大幅度提高了成熟期伤流液中钾的累积量.控释肥能够降低K+与Ca2+、Mg2+拮抗作用,提高钾的有效性... |

| Abstract: | The effects of controlled release fertilizer of soil characteristic,bleeding sap and root activity of tobacco are studied by nutrient release experiment of controlled release fertilizer and pot experiment of tobacco.The results show:with the controlled release fertilizer,the soil nutrient content and nutrient space efficiency are improved;potassium content in soil solution is increased,and nutrient content in soil solution reaches the maximum in growing peak period;nutrient accumulation in bleeding sap is i... |
| Keywords: | controlled release fertilizer nutrient release potassium content bleeding sap root activity |
