Flue-cured tobacco nutrition bag seedling is an advanced nursery technology.The advantage is that the root system of tobacco seedling development, strong seedling, high survival rate after planting, Huanmiao fast, enhanced disease resistance, quality of production. Nutritional bag nursery in two Stage, the first stage is by conventional law nursery, nurture a certain number of mother bed seedlings. When the mother bed about 1 month seedlings grow 4-5 true leaves were selected disease-free seedlings planted in the vegetative bag , Enter the second phase.Nutrient bags in the proportion of nutrition soil preparation is: 50-60% maturity of pig manure, mountain soil 40-50%, 1-1.5% compound fertilizer.Dung and soil to be dried mashed, mixed Uniform and then heat fumigation method or disinfection with 30-40% formalin.Manufacture nutrition bags in tobacco seedlings before planting, with newspaper or film paste made of high 10 cm, stem circumference
