Abstract:

Effects of adding different organic substances under common measure (CK) on physical properties and amino acid content was studied using flue-cured tobacco leaf in Nanyang of Henan . The result showed that: (1)Compared with the commonly used fertilizing measure ,the treatment added fermented soya-bean milk could obviously increase thickness, equilibrium moisture content, density of leaf fabric ,pulling ,tensile strength of tobacco leaves , and decrease filling value of tobacco leaves, while the treatments added sesame and bean powder appeared to the contrary current , and the treatment added gingili changed indistinctively . (2) The treatments added soybean had much higher total amino acid content ,and the treatments added products of sesame took the second place .Glu, Pro, Asp, Leu, Ala, Gly,Val,Lys, Phe ,and etc was higher which accounted for about 75 percent in every treatment of tobacco leaf, Pro, Asp,Thr, Ala was much higher in the tobacco leaf of treatments of F,E and D compared with other treatments, while Val, Tyr, Phe was higher in the tobacco leaf of treatment E.(3) Different organic substance brought different effect, among them, the two treatments by adding fermented soya-bean milk were the best, the treatment by adding bean powder took second place, and the other two added sesame and gingili were a little in the shade .
