Abstract:

To explore the improvement effect of turn-over green manure on the quality and economic value of flue-cured tobacco in Heilongjiang, this paper selected four types of green manure to turn down to study the effects. The green manure was decomposed on the spot after the harvest of flue-cured tobacco, and the physical and chemical indexes, the internal and external quality improvement of flue-cured tobacco were measured in the second year. The results showed that, at the end of July, interplanting green manure had little effect on the main economic characters and chemical composition of flue-cured tobacco, but the turn-over green manure could improve the chemical composition of flue-cured tobacco, among which the nicotine was decreased by 10.55%, the total nitrogen was decreased by 33.54%, the ratio of total nitrogen to nicotine was decreased by 25.93%, the total sugar was increased by 8.59%, the change of reducing sugar was not obvious, the ratio of total sugar to nicotine was increased by 21.41%, the content of potassium ions and chloride ions were increased by 12.50% and 12.00% respectively. Under the turn-over green manure, the leaf of flue-cured tobacco had good maturity, loose structure, high oil content and medium status. The weight of single leaf was increased by 15.46%, the leaf thickness was decreased by 17.86% and the ratio of tobacco stem to leaf was decreased by 5.93%. The species, content and aftertaste of the aroma were improved when the flue-cured tobacco was burned. The turn-over green manure could improve the chemical composition of flue-cured tobacco, the decomposition and transformation degree of carotenoids was increased by 12.95%, the conversion of aromatic amino acids was increased by 20.76%, the decomposition and transformation of Xibo-Alkanes was increased by 9.59%, the change of nonenzymatic browning was not obvious. The turn-over green manure could increase the production and economic value of flue-cured tobacco, among which the proportion of prime tobacco was increased by 35.59%, the production per hectare was increased by 5.65%, and the economic value per hectare was increased by 14.61%. Interplanting sweet clover and wheat has the best effect.
