摘要 [目的]研究壳寡糖有机水溶肥对烤烟云烟97生长发育和产质量的影响。[方法]采用田间试验,在减少30%复合肥施用量的条件下,对烤烟喷施不同质量浓度壳寡糖有机水溶肥,研究壳寡糖有机水溶肥对烤烟云烟97生长发育和产质量的影响。[结果]喷施壳寡糖有机水溶肥可缩短云烟97生育期,增加茎围、叶片数、叶面积和地上部、地下部干物质积累量,提高烟叶产量、产值和上等烟比例,利于感官质量的提升。[结论]云烟97的生育期和产质量随着壳寡糖有机水溶肥喷施浓度的增加而向好,其中400倍质量浓度的处理效果最好。

Abstract [Objective]To study the effects of NPSAN water soluble organic fertilizer on the growth and development and the yield and quality of fluecured tobacco Yunyan 97.[Method]A field experiment of applying different density of NPSAN water soluble organic fertilizer was conducted under the condition of reducing the application rates of compound fertilizer by 30 percent.[Result]Applying NPSAN water soluble organic fertilizer could shorten the growth period, increase tobacco stem girth, number of blades,leaf area,and the dry matter weight above ground and underground, and increase the yield, output value and proportion of the topclass leaf, which was conductive to the improvement of sensory quality. [Conclusion]The growth period and yield quality of Yunyan 97 improved with the increase of density of NPSAN water soluble organic fertilizer , and the effect of 400 times was the best.

烤烟是云南省重要的经济作物之一,对全省的社会经济发展有重要影响[1],优质、安全、质量稳定的烟叶对卷烟工业的可持续发展至关重要[2-4]。化肥的大量使用,造成土壤板结、盐碱化及农业污染,对生态环境、人类健康等构成了严重威胁[5-6]。目前国内已报道了多种有机肥在烤烟生产中应用的相关研究,并取得了一定的成效,但国内已有的有机水溶肥料种类繁多且质量不一[7-13]。因此,探索更好的生态种植技术以及找到更加生态、高效的优质有机水溶肥料的工作显得十分迫切。笔者选用壳寡糖有机水溶肥料,对烤烟云烟97喷施不同的质量浓度,探索其在烤烟生产上应用的最佳方案与科学参数,以期达到减少化肥使用量、促进烟叶生长发育、提高烟叶产质量、增强烟草抗病力的目的。……
