一、什么时候收获

在一般情况下，它会在清明节前后的时候播撒种子，从霜降时期，茎叶全部枯萎时就开始采收，大约在10-11月份。如果采收过早会造成产量比较低的情况，并且含水量还很多容易折断。如果不着急上市，可以适当的延长，在地里面保存度过冬天，最晚可以延迟到第二年的3月份。这是对于露天种植的来说，它的收获期会比较的长，但是大棚里面种植的不同，一般在6月20日左右。

二、有药性吗

它具有一定的药性，根茎的部位可以用来入药，是一种常见的中药，可以延年益寿，促进消化。也可以当做普通食物，已有3000多年的时间渊源，一般人食用的话，对于身体也是具有很多好处的，一般人群都能够食用，被誉为补虚佳品，备受人们的称赞。
