辽宁烟区土壤保育与修复技术研究

土壤是影响烟叶质量的首要环境因素。植烟土壤的保育与修复技术是解决烟叶质量发展瓶颈问题的关键。以辽西朝阳为例,通过对种植制度、精准施肥技术、土壤改良技术和土壤修复技术进行分析,找出原因,修复植烟土壤物理结构、平衡土壤养分、改善土壤生态环境、减少病虫危害,保持现有健康土壤不再退化,实现退化土壤逐渐修复,维护烟区烟叶生态安全的红线,达到烟叶质量提升和种烟效益增加的目标任务。

The Conservation and Restoration Technology of Tobacco Planting Soil in Liaoning Tobacco-planting Area

Soil is the primary environmental factor affecting tobacco quality. The conservation and restoration technology of tobacco planting soil is the key to solve the bottleneck of tobacco quality development. By analyzing the planting system,precision fertilization technology,soil improvement technology and soil restoration technology,this paper found out the reasons for repairing the physical structure of soil-growing soil,balancing soil nutrients,improving the soil ecological environment,reducing pests and insects,and keeping the existing healthy soil from being degraded. It will gradually repair degraded soils,maintain the red line of leaf ecological safety in tobacco areas,and achieve the goal of improving tobacco quality and increasing tobacco yield.
