摘要
在云南腾冲通过田间试验研究了在土壤中加入15%火山灰石砾对烟株生长、病害、烤后烟叶产量、化学成分及色素和多酚含量的影响。结果表明,水田试验添加火山灰石砾处理烟株在前期生长较快且差异显著(P<0.05),烤后烟叶产量产值分别达3 247.05 kg/hm2,57 148.08元/hm2,显著(P<0.05)高于对照处理,化学成分更协调,类胡萝卜素含量较高,处理间多酚含量无明显差异;旱地试验添加火山灰石砾处理烟株赤星病和普通花叶病发病程度显著(P<0.05)低于对照,烤后烟叶产值、中上等烟比例及均价分别为48 407.13元/hm2,72.10%和17.3元/kg,显著(P<0.05)高于对照处理,化学成分更协调,处理间色素和多酚含量无明显差异。
Field experiments were conducted to study the effect of by mixing volcanic gravel into soilon growth, tobacco diseases, yield, chemical composition and contents of the pigment and polyphenol of flue-cured tobacco in Tengchong, Yunnan province. The results showed that in paddy fields experi-ment, tobacco of the treatment grew more rapidly at the early growth stage and had significant difference （P 〈0. 05） , the yield was about 3 247.05 kg/hmZand the economic value was about 57 148.08yuan/hm2, they all were significantly higher than CK （ P 〈 0. 05 ） , the chemical composition of fluecured tobacco was more harmonious, the content of the pigment was higher but there was no significantdifference on the content of polyphenol. In the dry land experiment, the incidence and disease index of tobacco brown spot and TMV in the treatment were lower significantly than CK （P 〈 0.05 ）, the eco-nomic value was about 4 8407. 13 yuan/hm^2, the proportion of middle-superior 72. 10% and the average price was about 17.3 yuan/kg, they all were significantly higher than CK（P 〈0. 05 ）, the chemical composition of flue-cured tobacco was more harmonious, there was no significant difference on the content of polyphenol and pigment.
