摘要
选择笋竹两用毛竹林,采用等量施肥技术,开展分期施肥试验,筛选出等量施肥优化模式。结果表明:每度竹施肥2次,其竹笋产量较施肥1次提高6.7%,较施肥3次提高6.8%;其竹材产量较施1次提高18.9%,较施肥3次提高12.6%;每667m2年产值较施1次提高14.8%,较施肥3次提高12.4%。因此,笋竹两用毛竹林合理施肥模式为每度竹施肥2次(春笋小年的6月、8月)。
In order to optimize the mode of equal fertilization technology, timber-shoot Phyllostachys edulis forests were chosen to carry out the split fertilization experiment by applying the equal fertilization technology. The results showed that Ph. edulis forest fertilized 2 times produced the shoot yield 6.7% and 6.8%, respectively, higher than those fertilized 1 time and 3 times, and had the timber yield with the increase of 18.9% and 12.6% compared with the forest fertilized 1 time and 3 times. The output per 667 m2 of the bamboo forest with 2 fertilizations increased by 14.8% and 12.4% compared with those with 1 fertilization and 3 fertilizations. Therefore, the optimal fertilization mode for timber-shoot Ph. edulis forest was to fertilize 2 times at June and August during the off-year for spring shoot.
