花生麸与无机肥配施对烤烟产质量和土壤肥力的影响

摘要

In 2008 , field experiments were conducted to study the effects of different ratias of peanut bran fertilizer on the growth of tobacco plant , absorption of nutrient and soil fertility. The results showed that tobacco plants treated with peanut bran fertilizer showed no significant change on plant beight, stalk diameter and leave number. Tobacco yield, mean price and rate of leaves with high quality significant increased under different ratios of peanut bran fertilizer. The content of K, Lotal augar, protein in central leave and lower leave decreased. The total K.total sugar, reducing sugar, nicotine, protein and othcr main chemical components in all leave tended to coordinate in a range of high-quality content in flue-cured tobacco under treatment with 20 ％ peanut bran fertilizer. Soil alkali-hydrolyzable N, available P, K and organic matte were found to be greater uridcr those treated with peanut bran fertilizer than those in CK. Moreover, with the increasing of radioa of peanut bran fertilizer, the soil fertility increased aignificant. Considering all indicators for the growth of tobacco plant, economical characteristics and yield and quality of flue-cured tobacco. higher yield and quality of tobacco were produced under 20 ％ peanut bran fertilizer. Therefore, it was conaidered as the optimum fertilization pattem.%为了改良植烟土壤,提高烤烟品质和安全性,2008年,采用田间试验的方法,研究花生麸与无机肥配施对烤烟生长、养分吸收及烟田土壤肥力的影响.结果表明:花生麸与无机肥配施的烟株生长无显著变化,但烤烟产量及上等烟比例显著提高;烘烤后中、下部烟叶全钾、总糖含量提高、烟碱降低,以20%花生麸配施烤烟上、中、下部烟叶全钾、总糖、还原糖、烟碱、蛋白质含量等主要化学成分更趋于优质烤烟含量范围;土壤肥力显著提高,且随花生麸配施比例的增加而增加.综合烤烟烟株生长、经济性状及烟叶品质,以配施20%花生麸生产出的烟叶产、质量较为理想,是烟田土壤较优的花生麸配施模式.
