In order to enrich the variety of autumn vegetables and meet the needs of pickled processing, Mudanjiang Agricultural Research Institute Horticultural Research Laboratory after years of testing and exploration, summer sowing lettuce has been successful, in 1984 made the commodity lettuce (except leaf removal) per mu 4,288 pounds , The average weight of 9 two plants, the highest single plant weighing 1.8 pounds of good harvest. Compared with the spring lettuce (general mu produce 2,000-3,000 pounds), the output increased 43-114%. Summer sowing lettuce cultivation is the key to success or failure: First, the choice of seed: lettuce summer sowing when the hot weather, should use the tip of the middle and late varieties, can not choose round leaf type
