摘要
针对云南省松茸产量连年锐减的严重现实 ,通过对松茸产区及市场的深入了解 ,结合在林间试验地的研究和观测调查 ,提出一系列促进松茸可持续发展的途径。禁止采收和收购占松茸总量约36 .4 %的未成熟幼茸 ,可使云南松茸在现有基础上增产 1.96倍 ;在保持现有松茸生态环境条件下 ,采用科学的采收方法 ,实施一系列有关的科学技术措施 ,在 2 7hm2 范围内松茸产量连年成倍增加 ;在 1hm2试验林范围内 ,松茸个数增加 4 5.2 8% ,产量增加 4 8% ,而有关鸟害等损失则降低 ,森林生态环境得到改善 ,土壤营养条件也不同程度得到改善。因此 ,恢复和保护松茸生态环境并配合适当的技术措施与科学的采集方法 ,更适合当前云南松茸的发展以及经济效益的进一步提高。
There was a dramatic decrease of the yield of Tricholoma matsutake in Yunnan Province in recent years.An investigation on the production area and market was made and some research works were conducted in the experiment plots.Some proposals about promoting the sustainable development of T.matsutake were suggested.By prohibiting the collection of un matured T.matsutake which takes 36.4% of the total T.matsutake production yield,the yield could increased by 1.96 times.By adopting scientific harvesting method and other countermeasures,preserving the suitable ecological environment,the yield of T.matsutake could double in successive years in an area of 72 hectares.In an experiment plots with an area of 1 hectares,the amount of T.matsutake increased by 45.28% and the yield increased by 48%.The ecological environment improved significantly.
