| 摘 要： | 针对连作产生的障碍,综述了连作与土壤理化性状、土壤微生物和土壤酶活性之间的关系,指出连作会造成土壤养分不平衡、土壤微生物区系发生变化、土壤物理性状和土壤酶活性朝着不利于作物生长的方向改变,是影响作物生长发育、产量和品质的主要原因。为此,提出了改良土壤、消除连作障碍的一些措施。 |

| Abstract: | Aiming at continuous cropping obstacle,the relationships between continuous cropping and soil physical and chemical characteristics,soil microorganism,soil enzymes activity were reviewed.The imbalance of soil nutrient,change of soil microorganism,changes of soil physical characteristics and soil enzymes activity which went against crop growth were the main reasons why continuous cropping influenced crop growth and developing of yield and quality.Thus three methods were put forward for the improvement of the soil and elimination of continuous cropping obstacle. |
| Keywords: | Continuous cropping Soil characteristics Research advance |
