| Abstract: |
| In order to solve the problem of drought stress on yield and quality of flue-cured tobacco, the research used a field test method of dry rained soil reservoir water storage mode to study the effect of flue-cured tobacco agronomic characteristics, physical properties, chemical composition and the yield and output value. The results showed that the comprehensive performance of agronomic characteristics by T treatment (soil water storage model under rainfed condition) was better than CK treatment (control group), and the growth of flue-cured tobacco was uniform and had stout stem. The differences in leaf weight and quality between two treatments were significant and all parts of tobacco leaf weight and quality by the T treatment were higher than CK, and the leaf weight and quality of middle leaf were 22.90 g and 76.67 g·m-2, respectively. Fill value and stem ratio of upper leaves of T were 3.64 cm3·g-1 and 26.29%, respectively, significantly lower than those by the CK treatment. In the upper and middle leaves, the equilibrium moisture content by the T treatment was higher than that of CK, and the difference was significant. The T treatment could improve the chemical components of tobacco. Also, it significantly improved potassium content and potassium chlorine ratio in different parts of tobacco leaf, and the mean values were 2.74% and 6.89, respectively. In addition, compared with CK, it significantly reduced the total nitrogen, nicotine and chlorine contents. In conclusion, soil water storage model under rainfed condition could improve the leaf yield and output value, and the production of tobacco was 2 156.7 kg·hm-2, significantly higher than that from CK. |
