在我国南方冬季无霜地区,芦笋没有明显和充分的休眠期,全年幼茎不断的生长和发育,又加之采收期长(第一次采收于3月下旬至7月上旬,第二次采收于8月中旬至10月下旬),造成地下茎中贮藏的养分消耗多而积蓄差,在这样的地区,如仍按照温带地区的常规采收方法,势必达不到优质高产的目的.为解决这一问题,我们于1987年开始进行了“留茎”采收.
In southern frost-free areas in southern China, asparagus has no obvious and sufficient dormant period. The annual growth of young stems and development, combined with the long harvest period (the first harvest in late March to early July, the second The secondary harvesting is from mid-August to late October), resulting in more nutrients stored in the underground stems and poor storage. In such areas, the conventional harvesting methods in temperate regions are bound to fail to achieve high-quality and high-yielding purposes. To solve this problem, we began in 1987, “stay stem” harvesting.
