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。
A field experiment was conducted in Tengchong, Yunnan Province to study the effects of adding 15% volcanic ash rock gravel on the growth, disease, yield, chemical composition and pigment and polyphenol content of tobacco after roasting. The results showed that the addition of volcanic ash gravel in paddy soils had a rapid growth and significant difference (P <0.05), and the output value of cured tobacco reached 3 247.05 kg / hm2 and 57 148.08 Yuan / hm2, respectively, significantly (P <0.05 ) Were higher than the control, the chemical composition was more coordinated, the carotenoid content was higher, and there was no significant difference in the content of polyphenols between the treatments. The incidence of brown spot disease and common mosaic disease was significantly increased by adding volcanic ash gravel in the dry land experiment (P <0.05 ) Were lower than the control, the output value of roasted tobacco, the proportion and the average price of middle and upper tobacco were 48.07.13 yuan / hm 2, 722.10% and 17.3 yuan / kg respectively, significantly higher than that of the control (control) There was no significant difference in the contents of pigments and polyphenols between treatments.
