毛竹笋材两用林生态高效经营利用的研究及示范推广

针对毛竹产业发展的技术需求，在国家中央财政、省林业厅等项目支持下，开展毛竹笋材两用林生态高效经营利用的应用基础理论研究、技术研究集成与推广应用。主要内容为：①毛竹营养与竹林施肥理论研究 ②人工经营对毛竹林土壤质量与植物物种多样性变化的影响 ③人工经营毛竹林生态高效土壤养分管理模式研究 ④毛竹钩梢技术对雨雪冰冻灾害的防治的研究 &#61550 霍山县毛竹科技示范园区建设及实施效果研究 &#61551 毛竹笋加工利用技术研究。取得的主要成果： 完善了毛竹施肥理论。项目组通过对毛竹氮素吸收形态偏好性研究，首次提出了毛竹属于兼性喜硝植物 不同氮源对毛竹的生长特性也有明显的影响，硝态氮能促进毛竹幼分蘖，而铵态氮能促进主茎的持续生长 推动了毛竹施肥理论研究。 明确了人工经营对竹林生态的影响特征。以不同经营模式的竹林为研究对象，探讨了①人工经营对毛竹林土壤物理与化学性质的影响 ②人工经营对土壤碳氮循环的影响 ③毛竹经营对植物多样性的影响。研究结果表明人工经营导致的土壤扰动会导致土壤容重下降，碳氮循环加速 人工经营导致竹林产出增加，施肥不足会造成土壤养分下降。为开展毛竹笋竹两用林生态高效经营提供了理论依据，在实践中提出了减少土壤干扰及混交经营的技术措施。 提出了人工经营毛竹林养分动态管理模式。通过对当前人工经营毛竹林的土壤养分特征进行探讨，发现当前不合理的人工经营措施已造成毛竹林土壤养分衰退，生态功能退化，威胁到毛竹产业的可持续发展。本项目基于竹林经营方式的特殊性，结合竹林培育的发展趋势，提出了生态优先、模式多样、动态变化的人工经营竹林养分管理模式。发现该模式显著提升了竹林土壤养分状况，维护了竹林生产力，对竹林培育的可持续发展具有重要作用。 集成毛竹笋材两用林高效培育技术体系并以示范园区为载体进行技术推广。项目组自2009年起，在霍山县诸佛庵镇开展了安徽霍山毛竹现代科技园区建设。针对毛竹笋材两用林生态高效经营技术进行了集成。构建了&#61546 竹林结构动态调整技术 竹林土壤管理技术 竹林水分管理 竹笋采收技术 毛竹砍伐技术 毛竹钩梢技术 竹笋无公害生产技术等生态高效培育技术体系。 开发了竹笋加工技术。引进并改造了清水笋和脱水笋加工技术，现已达到年加工鲜笋3000吨的生产规模。

To address the technical demands of the moso bamboo industry, supported by projects funded by the central national finance and provincial forestry departments, this study conducted applied basic theoretical research, technical integration, promotion and application of ecologically efficient management and utilization of moso bamboo shoot and timber dual-purpose forests. The main contents include:
1. Theoretical research on moso bamboo nutrition and bamboo forest fertilization
2. Impacts of artificial management on changes in soil quality and plant species diversity of moso bamboo forests
3. Research on ecologically efficient soil nutrient management models for artificially managed moso bamboo forests
4. Research on the effect of moso bamboo shoot-tipping technology in preventing rain, snow and freezing disasters
5. Research on the construction and implementation effects of the Huoshan County moso bamboo science and technology demonstration park
6. Research on processing and utilization technology of moso bamboo shoots

The main achievements are as follows:
1. Improved the moso bamboo fertilization theory. Through research on the preference of moso bamboo for different nitrogen uptake forms, the research team first proposed that moso bamboo is a facultative nitrate-loving plant. Different nitrogen sources have significant effects on the growth characteristics of moso bamboo: nitrate nitrogen promotes the tillering of young moso bamboo, while ammonium nitrogen promotes the continuous growth of main stems. This finding advanced the theoretical research on moso bamboo fertilization.
2. Clarified the impact characteristics of artificial management on bamboo forest ecology. Taking bamboo forests with different management models as research objects, the study explored: (1) The impact of artificial management on the physical and chemical properties of moso bamboo forest soil; (2) The impact of artificial management on soil carbon and nitrogen cycles; (3) The impact of moso bamboo management on plant diversity. The research results show that soil disturbance caused by artificial management leads to a decrease in soil bulk density and accelerated carbon and nitrogen cycles; artificial management increases bamboo forest output, while insufficient fertilization causes a decline in soil nutrients. This study provides a theoretical basis for carrying out ecologically efficient management of moso bamboo shoot and timber dual-purpose forests, and proposed technical measures of reducing soil disturbance and mixed management in practice.
3. Proposed a dynamic nutrient management model for artificially managed moso bamboo forests. By discussing the soil nutrient characteristics of current artificially managed moso bamboo forests, it was found that current unreasonable artificial management measures have caused soil nutrient decline and ecological function degradation of moso bamboo forests, threatening the sustainable development of the moso bamboo industry. Based on the particularity of bamboo forest management methods and combined with the development trend of bamboo forest cultivation, this project proposed an artificial bamboo forest nutrient management model with ecological priority, diverse models and dynamic changes. It was found that this model significantly improves the soil nutrient status of bamboo forests, maintains bamboo forest productivity, and plays an important role in the sustainable development of bamboo forest cultivation.
4. Integrated the efficient cultivation technology system for moso bamboo shoot and timber dual-purpose forests and carried out technology promotion with the demonstration park as the carrier. Since 2009, the research team has carried out the construction of the Anhui Huoshan Moso Bamboo Modern Science and Technology Park in Zhufuan Town, Huoshan County. Integrated the ecologically efficient management technologies for moso bamboo shoot and timber dual-purpose forests, and constructed an ecologically efficient cultivation technology system including: dynamic adjustment technology of bamboo forest structure, bamboo forest soil management technology, bamboo forest water management, bamboo shoot harvesting technology, moso bamboo felling technology, moso bamboo shoot-tipping technology, and pollution-free bamboo shoot production technology.
5. Developed bamboo shoot processing technology. Introduced and transformed the processing technologies of clear-water bamboo shoots and dehydrated bamboo shoots, and now has reached a production scale of processing 3,000 tons of fresh bamboo shoots per year.
