摘要
试验研究了雷竹笋用林最佳的首次覆盖林龄、每年开始覆盖的时间及覆盖物清除时间。结果显示:6年生林分在连续5 d最高气温降至低于20℃、地温降至低于10℃时开始覆盖、惊蛰前清除覆盖物,林分年度竹笋产量和持续产量均较好。
The optimum bamboo forest age for the first mulching, and the time for start mulching and removal each year are studied in Phyllostachys violascens forest. The results show that the annual shoot yield and constant shoot yield of the 6-year-old bamboo forest are higher with the start mulching after the maximum temperature dropped below 20 ℃ and the ground temperature dropped below 10 ℃ for 5 consecutive days, and removed the mulching before the Waking of Insects.
