科学采收：不结球生菜可根据市场价格适时采收，结球生菜以叶球紧密后采收为好，过早会影响产量，过迟则叶球内茎伸长，叶球变松品质下降。
Scientific harvesting: non heading lettuce can be harvested at the right time according to the market price. It is better to harvest lettuce after the leaf ball is tight, which will affect the yield too early. If it is too late, the stem in the leaf ball will elongate, and the quality of the leaf ball will decrease.
