I. Introduction to the model
In order to increase the benefits of tobacco farmers, the adoption of intercropping tobacco cultivation can greatly increase the land utilization rate, increase the income of tobacco farmers, and alleviate the contradiction between vegetable and tobacco competition. The vegetable varieties suitable for cultivation of inter-plant tobacco are preferably cruciferous and liliaceous vegetables. In the early stage of growth, the tobacco leaves are small in individual plants and have limited absorption of water and fertilizer. The area of ​​free land is large, and a quarter of vegetables are planted in the early stage of tobacco growth. In the latter stage of the growth of vegetables, tobacco and vegetables are harvested again. At the same time, peasants have become busy and have increased the utilization rate of the labor force, staggered the seasonal contradictions and reduced the waste of resources.
Second, technical points and parameters:
Intercropping Chinese cabbage: In the area of ​​800 to 1,400 meters above sea level, in late March and late March, the sowing date of Chinese cabbage is delayed with the rise of elevation, and no later than the end of March, nourishing seedlings are transplanted and when the seedlings reach 4 When the leaves and the heart were planted in Daejeon, they were harvested from late May to early June. The leaf nursery was carried out in mid-March. When the tobacco leaves reached the group tree, cabbage was harvested. The symbiotic period of tobacco in the same field was 1 Months or so.
Between the tobacco leaves as radish: In the area of ​​800 to 1,400 meters above sea level, in early April to late radish (small shed) sowing, take the live broadcast. Planting tobacco leaves from mid-May to early June. The symbiotic period of tobacco is about 1 month.
Intercropping of Cabbage among Tobacco Leaves: In suitable tobacco areas, cabbage seedlings were planted in early January, colonized in mid-March (small arch), and tobacco was planted from mid-May to early June, and harvested after 1 month of planting. The symbiosis time for cabbage and tobacco fields is about 1 month.
Lettuce among tobacco leaves: Lettuce includes lettuce and loose leaf lettuce. The nursery was started from early March to late, and planted from early April to late. Planting of tobacco leaves from mid-May to late, and lettuce harvesting from early June to late.
Intercropping tobacco with garlic: Garlic was selected as the main cultivar of Zizi in western Hubei. Garlic is planted from late September to mid-October, reserved for tobacco leaves, planted tobacco leaves in the middle of May the next year, and harvested garlic in early July. (The characteristics of the variegated cultivar in West Hubei require open-field cultivation until mid-July. In order to collect), the symbiosis period of garlic smoke is one and a half months. After the tobacco leaves are harvested, broad beans are grown.
Technical route:
Cabbage (including cabbage, white radish, lettuce, etc.) seedlings (or sowing)? Chinese cabbage colonization (including cabbage, white radish, lettuce)? Tobacco leaf colonization? Chinese cabbage and other vegetables harvested? Sowing (800 to 1200 meters above sea level)
Garlic (onion) sowing, tobacco seedlings, tobacco colonization, garlic harvesting, tobacco harvesting, broad bean seeding
Third, suitable varieties:
The origin of the “Ehyan No. 3†cultivar was originally named 9803. The source of the cultivar was jointly selected by the Hubei Provincial Tobacco Company Jianshi County Company and the China Tobacco Burley Tobacco Experimental Station. The type of plant is barrel-type, plant height 130cm ~ 140cm, plant height 127.1cm, leaves 29, collectable leaves (22 ~ 24). Leaf oval, waist length 72.7cm, waist width 34.92 Cm, stem circumference 11.77cm, pitch 4.57cm; stem and leaf angle is smaller, leaf surface is wrinkled, tip tip is acuminate, leaf is yellow-green, leaf thickness is uniform, main veins are medium and thick, leaves are even and compact, inflorescences are concentrated, Pink color. Daejeon has a fertility period of about 90 days and is a mid-maturing variety. Resistant to water, more drought-resistant, strong adaptability. Strong growth in the field, resistance to black shank disease, root black rot, middle resistance to mosaic disease, weather-resistant spot disease, and disease. After preparation, the original tobacco was nearly red-yellow, with strong elasticity, bright brilliance, loose leaf structure, moderate thickness, and suitable for planting in China. The medium fertility plot uses 12.5kg to 13kg of pure nitrogen per acre, and the nitrogen:phosphorus:potassium ratio is 1:1:1.5. In the middle and late May, transplanting is carried out, the top of the flowering stage is topping, and the leaves of the single leaves (22-24) are used. . More than 1100 plantings per mu (667m2), producing 160kg to 175 tons per mu? About K, you can leave enough smoke to increase production. The proportion of upper-middle smoke is 85-90%.
