First, the production of quality indicators 1, yield indicators The output of aromatic tobacco is about 80 kg per mu. 2. Appearance quality of quality indicators: The color of the top leaves and the top two shed leaves is orange, dark yellow, red and yellow, and the lustre is bright. The identities are thick, the oil is rich, and the organization is meticulous or slightly detailed; the lumbar leaves are yellow, golden, and deep in color. Yellow, shiny and bright, identity medium to thick, full of rich oil, the organization a little more detail; the second shed leaves, dark yellow, is yellow, gloss is still clear, thin identity, the organization is loose. Chemical composition: total sugar 15% to 17%, nicotine 0.8% to 1.5%, total nitrogen 1.8% to 2.3%, protein 8% to 11%, chlorine content below 1%. Shimu Ke value 1.5 ~ 2.5, pH value of about 5. Intrinsic quality: Significantly aromatic smoke characteristics, aroma volume is sufficient, aroma quality is good, irritation is slight, momentum is moderate, aftertaste is comfortable, flammability is strong, grey white. Second, the individual morphology indicators Plant type: cylindrical or tower-like; plant height: 115 ~ 125 cm; stem circumference: 3 ~ 3.25 cm; single leaves: 28 ~ 32; Leaf length 8 ~ 12 cm, leaf-shaped ellipse, waist and upper two shed length 14 to 18 cm, leaf-shaped ellipse, the next shed and foot length 18-20 cm: single leaf weight: 0.4-0.7 grams. Third, the population index field tobacco plants in the same orderly growth, plant height, the same site leaf size, leaf color and leaf thickness are basically the same, no pests and diseases. Leaf area coefficient 3-3.5. IV. Cultivation Techniques 1. Selection of Fine Varieties: Baxthi Basma and Komotini have been approved for promotion in our province. All of them were imported from Turkey and Greece after 1989. They were selected after many years of test and appraisal, production demonstration, and industrial verification. They have excellent quality, drought resistance, and disease resistance (resistance to witches' broom, virus resistance) And bacterial diseases, susceptible to powdery mildew) characteristics suitable for planting in Yunnan tobacco, can be selected according to local conditions. Seeds: Uniform use of high-quality coated seeds supplied by tobacco companies. 2. Seedling raising: Due to the large planting density of oriental tobacco and the high cost of floating seedlings, conventional breeding techniques are still used. The selection of seedbeds generally requires leeward sunny, flat terrain, proximity to water sources, convenient irrigation and drainage, sandy loam soil and paddy field soil, close to tobacco fields or convenient transport of tobacco seedlings, and no tobacco or vegetable plots were planted within three years. The area ratio of seedbed seedbeds to Daejeon is 1:1.5 to 20, and the planting area per acre of Daejeo needs about 30 to 40 square meters of seedbed area. After the nursery bed is selected, the seedling bed will be ploughed and sun-dried. The dry land is made of high-stemmed low-lying sorghum, which is 1 meter wide. The length of the sorghum is determined by the topography and generally does not exceed 10 meters; the rice field nursery is made into a high sorghum low ditch or double cocoon, with a width of 1 meter and a ditch depth of 20 meters. Rice, width 30 cm, length determined with the terrain, the surface is flat, and the nutrition land is laid. The preparation of nutritious soil is mixed with decomposed fine feces in a ratio of 1:3. Each 50 gram of compound fertilizer or potassium nitrate, insecticide, and bactericide is sprayed on the nutrient soil, and the stacking is 3 to 5 tiles. In the seedbed, the thickness of 3 to 5 cm. Seedbed and nutrient soils can be used for disinfection of seed beds in Simei. Seeding sowing time: According to the transplanting period, sowing 60 to 70 days before transplanting. Seeding rate: 0.5 to 1 gram of naked seeds per 10 square meters of net area, or 5 to 6 packets (0.01 kg/pack) of coated seeds, and about 6,000 seeds. Seeding method: Each gram of seeds and fine soil or river sand or rotted Organic Fertilizer sieved 1 to 2 centimeters, spread vertically and horizontally so that the seeds are evenly distributed in the pupa.
