Variety selection The mid-late-maturing late-maturing cabbage lettuce varieties with strong cold resistance were selected for cultivation.
Cultivation date Sunlight greenhouse cultivation can be planted from mid-late November to late January and harvested from mid-January to early March.
Seedlings choose fertile sandy loam soil, made it flat and finished. Then every 10 square meters of high-quality manure applied sieved 100 kilograms, potassium dihydrogen phosphate 0.5 kilograms, fully mixed, after the leveling surface watering, water infiltration after seeding. Dry seeds are generally used for sowing, but they can also be sowed after germination. Dry seeds are sown with 75% chlorothalonil wettable powder at a seed weight of 0.3%, but should not be allowed to stand for too long. Immersion seed germination, first soaked in warm water 20 °C for 6-7 hours, remove and wrap it in a cloth bag, place germination at 20 °C, washed once a day with water, buds after 2-3 days. Select sowing on a sunny day without wind, sowing 3-5 grams seeds per square meter of seedbed. After sowing, a layer of 3-5 mm thick fine soil was applied.
Before the site preparation and fertilization, 5000 mu of composted organic fertilizer and 30-40 kg of compound fertilizer were planted. After the deep plowing, it is made into a flat bark, and the plastic film can be covered with a small puppet.
Planted in a greenhouse, the general spacing is 40 centimeters, and the spacing is 30 centimeters. Before the seedlings are planted, they are watered and chopped, adding more soil. Open ditch or dig planting, seal ditch flat water after planting water.
After planting, the daytime temperature was maintained at 20°C-24°C and nighttime temperature was above 10°C. During the period of easing, cultivating loose soil 1-2 times. Appropriate cooling after easing the seedlings, during the day to 15 °C -20 °C is appropriate, and in the 7-10 days after the slow seedling seedling water, while light application of chemical fertilizer, apply 10 kg per acre. Afterwards, cultivating again and seedlings appropriately. About 15 days later, when the rosette leaves have grown and the heart leaves start to wrap, 15-20 kg of compound fertilizer or ammonium nitrate is applied, and the fertilizer is topdressed once more. The number of times of watering in winter should not be too much to prevent the ground temperature or humidity from being too high. When entering the ball stage, the water supply should be uniform. Do not dry or damp, so as to avoid cracking the ball or opening the ball. Stop watering 3-5 days before harvesting.
