遵义植烟土壤类型对烟草品质的影响

目的]研究遵义植烟土壤类型与烟草品质的关系,以探讨土壤类型与烟草种植的适配性,为遵义市合理规划植烟区提供资料。方法]对遵义4种植烟土壤的烟草的物理性质、化学成分和感观质量进行分析。结果]从烟叶的物理性质综合分析,4种土壤的差异显著（P〈0.05）,单产水平以水稻土最高;从烟叶常规化学成分分析,4种土壤的差异不明显（P〉0.05）,但从不同土壤烟叶化学成分比例的协调性分析,最好的为黄壤（P〈0.05）;从烟叶感观质量评吸分析,在3种旱作土（黄壤、石灰土、紫色土）上生长的烟叶质量好于水稻土（P〈0.05）。结论]遵义最适宜的植烟土壤主要为黄壤和石灰土,在规划上应选择这2种土壤作为植烟土壤。

Effects of Different Types of Tobacco Cultivated Soil on Tobacco Quality in Zunyi

Objective] The relationship between tobacco quality and types of tobacco cultivated soil in Zunyi was studied to discuss the suitability between agrotype and planting of tobacco,and then provide the relative information for the reasonable design of tobacco-growing region in Zunyi.Method] This study analyzed the physical appearance,chemical composition,and the sensory quality of tobacco of four tobacco cultivated soils in Zunyi.Result] The results showed that four soils appeared significant differences from the comprehensive analysis of physical apearance of tobacco(P<0.05),the yield level of per unit area of paddy soil was the highest in four soils.Four soils did not appear significant differences from the analysis of chemical composition of tobacco(P>0.05),but the compatibility of yellow soil was the best in four soils by analysis of chemical composition in different soils(P<0.05).However,the quality of tobacco three upland soil(yellow soil,rendzina soil,and purple soil) was better than paddy soil from the analysis of the sensory quality of tobacco(P<0.05).Conclusion] The optimum tobacco cultivated soil is yellow soil and rendzina soil,which indicated that the two soils were applied to plant the tobacco in programming.
