对福建省永安安砂水库周边一重山的糙花少穗竹林采取等高隔带浅翻处理(DGQ)、错位品字型块状全锄处理(CKC)、等高隔带浅翻(深度3~5 cm)+施肥处理(DGF)、全面劈山处理(QPS)、全面浅翻处理(QCK)抚育技术,研究其对竹林的生长效应以及土壤水分物理性质和土壤涵养水源能力的影响。结果表明:平均胸径从大到小依次为:DGF>DGQ>QCK>CKC>QPS处理;笋产量和竹材产量从高到低均依次为:DGF>DGQ>QCK>CKC>QPS处理,方差分析和多重比较结果表明:DGF、DGQ与QPS处理间,DGF与CKC处理间笋产量差异均达到极显著水平,DGQ与DGF处理间、CKC与QPS、DGF处理间笋产量差异均达到显著水平,其它处理间笋产量差异不显著;DGF、DGQ、QCK与QPS处理间,DGF与CKC处理间竹材产量差异均达到极显著水平,DGQ、QCK与CKC处理间竹材产量差异达到显著水平,其它处理间竹材产量差异不显著。DGQ和CKC处理竹林土壤水分物理性质和土壤涵养水源能力优于全面浅翻(QCK)和全面浅翻+施肥(DGF)处理,方差分析和多重比较结果表明:DGQ与QPS、QCK处理间土壤贮水力差异达到显著水平。说明DGQ、CKC处理平均胸径、笋产量和竹材产量不及全面浅翻+施肥(DGF)处理,但土壤水源涵养能力优于DGF和QCK处理,对于重要生态区位的糙花少穗竹林采取生态型DGQ处理和CKC处理是有效、可行的技术措施。
(CKQ), shallow shelf (depth 3), height of the upper shelf (CKQ), height of the upper shelf (depth 3 ~ 5 cm) + fertilization (DGF), QPS and QCK were studied to study their effects on the growth of bamboo forests and the physical properties of soil moisture and soil water conservation capacity. The results showed that the average DBH diameters were in order of DGF> DGQ> QCK> CKC> QPS. The highest bamboo shoot yield and the highest bamboo yield were DGF> DGQ> QCK> CKC> QPS, The results of multiple comparisons showed that there were significant differences in the shoot production between DGF and QPS, between DGF and CKC, and between DGQ and DGF, between CKC and QPS, and between DGF and CKC. The other treatments There was no significant difference in the yield of bamboo shoot between the two treatments. The difference of bamboo yield between DGF, DGQ, QCK and QPS treatments and between DGF and CKC treatment reached the significant level. The difference of bamboo yield between DGQ, QCK and CKC reached significant level. The difference was not significant. DGQ and CKC were superior to CKK and DGF in physical properties of bamboo forest and soil water conservation ability. The analysis of variance and multiple comparisons showed that soil storage of DGQ, QPS and QCK Hydraulic differences reached a significant level. The results showed that the average DBH, bamboo shoot yield and bamboo yield of DGQ and CKC treatments were less than that of DGF and DGF treatments. However, the soil water conservation capacity was better than that of DGF and QCK treatments. The ecological niche DGQ Treatment and CKC treatment is an effective and feasible technical measure.
