我国北方地区传统的采笋习惯为一年一季采笋,即春天采白笋或绿笋。在长期的生产实践中发现,芦笋生长到9月中旬以后再发出的嫩茎大部分都不能长成有效植株,一般在50～80厘米时就出现萎蔫死亡。主要原因是由于芦笋长到9月份后植株茂盛,通风透光不良,若遇秋旱,则易出现新茎萎蔫。针对这种情况我们设想秋季将这部分绿色嫩茎在 The traditional habit of collecting bamboo shoots in the northern part of our country is collecting bamboo shoots in one year, that is, picking white shoots or green shoots in spring. In the long-term practice of production, most of the young shoots that emerge after the growth of the asparagus until mid-September can not grow into effective plants, and the wilting death usually occurs at the time of 50-80 cm. The main reason is that as long as September asparagus plants lush, poor ventilation and light, in case of autumn drought, it is easy to appear new stem wilt. In view of this situation, we assume that this part of the green stem will be in the fall
