植烟土壤保育及改良技术的研究进展

Advances in Conservation and Improvement Technology of Tobacco-growing Soils

土壤条件是优质烟系统工程的基础,是影响烟叶质量的首要环境因素,植烟土壤保育与改良技术正从现代烟草农业土壤利用的普通问题发展为瓶颈问题。为及时解决植烟土壤有机质含量下降、土壤板结、生物活性降低、土壤酸化和土壤养分供应失衡等问题,有效推进特色优质烟叶生产和现代烟草农业发展。从烤烟种植制度、现代平衡施肥技术、土壤改良技术和重金属污染修复技术等方面进行综述,指出了植烟土壤保育和改良的发展方向。

Soil conditions,the basis of high-quality tobacco systems engineering,are the major environmental factors influencing tobacco quality.Conservation and improvement of tobacco-growing soils,a common question in soil utilization of modern tobacco agriculture,is now developing as a bottleneck problem.In order to timely solve such problems as soil OM content falling,soil hardening,biological activity decreasing,soil acidifying,and out-of-balance of soil nutrients supply,effectively promote the development of characteristic high-quality tobacco production and modern tobacco agriculture development,the authors reviewed flue-cured tobacco planting system,modern balanced fertilization technology,soil improvement technology and heavy metal pollution repair technology,and proposed the development direction of the tobacco-growing soils conservation and improvement.
