摘要
针对蔬菜地连作障碍,在深圳市郊两块黄瓜地进行高温闷地,并结合施有机肥、石灰和菌肥等土壤改良剂,以处理后两块黄瓜地的土壤温度、理化性质和黄瓜产量为指标进行调查分析。结果表明,该措施能够提高土壤温度,显著增加土壤中速效钾、交换性钙和镁元素的含量,改善土壤理化性质,黄瓜产量得到了显著提高。
Soil amendments, including organic fertilizer, lime and bacterial manure, and mulching were applied in two cucumber fields to improve cucumber continuous cropping soil in suburban areas of Shenzhen. After mulching and soil amendments, investigation of the soil temperature, physicochemical characters and edible yield of two cucumber plots were carried out. The results showed that the soil temperature and the contents of available potassium, exchangeable calcium and magnesium increased significantly. As the soil physicochemical characters improved, the cucumber yield increased dramatically through the combination application of mulching and soil amendments.
