Lettuce cultivation mainly in open cultivation, supplemented by facilities cultivation, can achieve the four seasons production, the annual supply. The delayed cultivation of greenhouses is a kind of cultivation method of autumn seedlings, planting in plastic greenhouses and other protected areas, and listing in winter, which provides high efficiency throughout the winter. First, the selection of varieties Lettuce seedling breeding period is in a high temperature and long-day environment, easy to make flower buds quickly differentiated and immature convulsions. Therefore, middle-late-maturing varieties with strong heat resistance, disease resistance, and unresponsive to long-day sunlight at the seedling stage should be selected, such as Nanjing Purple Peel and Chengdu Erqingpi. Second, the seed treatment of lettuce as hi-cold vegetables, the seeds began to germinate at 4 °C, 15 °C germination fastest, when the temperature exceeds 30 °C, the germination rate slowed or even blocked. When germination, the seeds should be soaked for 5-6 hours and germinated at a temperature of 15°C-18°C. Seeds can also be hung in deep wells 30 to 40 cm from the surface. During the germination period, the seeds were rinsed with water every day, and the seeds were exposed after 3 days. Third, timely sowing after the fall of the greenhouse cultivation of lettuce from sowing to harvest takes about 105 days, that is, from sowing to transplanting to 20 to 25 days is appropriate, transplanting to harvest takes about 80 days. The Shijiazhuang area can be planted from mid-August to early-September and harvested in December for reference elsewhere. Fourth, nurturing strong seedlings should be located in a relatively cool place, select fertilizers to maintain strong water, drainage and irrigation facilities, loose and fertile loam, and 7 to 10 days in advance to increase the amount of decomposed farmyard fertilizer, per acre applied maturity organic fertilizer 4000 ~ 5000 kg or 500 kg compound fertilizer is used as base fertilizer. Before planting, planting a foot of muddy water, each planting an acre of Daejeon seed amount of 20 to 25 grams. After sowing, cover 0.1 cm thick fine soil, then cover the shade net moisturize, if necessary spray water once a day. After the emergence of the shading nets. The seedbed can be covered with bamboo or shade nets, or it can be nursed under scaffolds or mixed with Chinese cabbage to form a cool and moist microclimate. Shading with bamboo curtains, shade nets and scaffolds requires daily uncovering. When the temperature is too high, water can be sprayed onto the bamboo blinds or the shade nets to cool down. Seedlings between the seedlings to 1 ~ 2 times, after the seedlings with 0.1% ~ 0.2% potassium dihydrogen phosphate spray foliar 1 or 2 times to promote strong seedlings. Fifth, greenhouse temperature and humidity management After late October, with the rapid decline in temperature, and the emergence of frost, should be covered shed film. The daytime temperature should not exceed 24°C, and the nighttime should not be less than 10°C. The early temperature should not be too high, otherwise it will lead to plant seedlings and diseases. Ventilation depends on the temperature conditions, to maximize the ventilation at the appropriate temperature for the growth of lettuce to maintain the relative humidity of 50% to 70%. If the humidity in the booth is too high, it should be promptly ventilated and loosely dampened. In sunny days, it is necessary to ventilate earlier and close the shed in the evening to prevent the occurrence of diseases. After the cold weather in the later period, to prevent the plants from freezing, when the temperature falls below 0°C, additional insulation curtains or small arch sheds should be added to the greenhouse to control the temperature of the shed during the day at 15°C to 20°C, and the nighttime temperature should not be lower than 5°C. should. Sixth, pest and disease control Lettuce relatively few pests and diseases. For the prevention and control of downy mildew, 58% of Ledomil 500 times, or 40% of Insamactyl Wettable Powder 200 times, or 72.2% Precloxone 800 times, etc., are used for alternation spraying. Sclerotinia is controlled by 70% thiophanate-methyl WP wettable powder 700 times, 50% fast-inking wettable powder 1500 times liquid or 50% acetaminophen wettable powder 1000 times liquid, etc. The prevention and control of gray mold must strengthen field management and enhance plant disease resistance. In the early stage of disease, 50% of methaminate WP can be sprayed with 500 to 800 times liquid. Lettuce pests mainly refer to tubers and hummocks, which can be controlled by 2000-3000 times of 10% imidacloprid and 3000 times of 2.5% deltamethrin EC. 7. Harvesting can be harvested at any time before the stem is sufficiently enlarged. When the tip of the lettuce is at the tip of the tallest blade, it is appropriate to harvest the stem of the lettuce. Autumn lettuce in order to extend the market period, can be used to pick up the growth point and buds in sunny days by hand, or from the beginning of the rosette period, spraying 350 to 500 mg/kg of CCC for 1 to 2 times every 5 to 7 days, or at the base During the hypertrophy, 500 mg/kg of Qingqingsu was sprayed once or twice every 5 days.
