Effects of Different Nutritive Soil Formulas on Growth, Yield and Quality in Flue-Cured Tobacco
The mushroom soil, humic acid and biological carbon were used as raw materials in this study to explore the effects of different nutritive soil formulas on growth, yield and quality of tobacco leaf.The results showed that the nutritive soils could promote the growth of plant, the development of root system, and the appearance quality and economic benefit of tobacco leaf.And the optimum was the normal nutritive soil+ humic acid 10g+ biological carbon 50g, in which the dry weight of the lower, middle and upper leaves increased by 1.04 g,1.59 g and 1.15 g, and the yield, output value, average price and first-class tobacco proportion rose by 9.04％, 463.47 RMB yuan/667m2, 1.4RMB yuan/kg and 8.8 percentage points, respectively, as compared with the CK.
