摘　　要：为明确湘西烟地绿肥还田条件下氮肥的适宜减施量,以箭舌豌豆和黑麦草为材料,研究了不同绿肥还田与减施氮肥对烟叶SPAD值的影响。结果表明:翻压箭舌豌豆的烟叶SPAD值高于黑麦草还田处理,翻压箭舌豌豆处理烟叶成熟较黑麦草还田处理要迟;翻压箭舌豌豆条件下可减施氮肥9 kg/hm2,翻压黑麦草则不可减施氮肥。In order to get the proper amount of reducing nitrogen after returning green manure in Xiangxi tobacco fields, u- sing common vetch and uegrass as materials, this paper studied the influence of different green manure and different re- ducing amount of the nitrogen on SPAD value of flue - cured tobacco. Results show that： the SPAD value of flue - cured tobacco in the field returningcommon vetch was higher than that of uegrass, and the maturation period of tobacco with common vetch as green manure was later than that of ryegrass. Using common vetch as green manure, the nitrogen quantity can be reduced by 9 kg/hm^2, while with ryegrassas green manure, the nitrogen quantity cannot be reduced.
