银杏是世界上最古老的珍稀树种之一,又是多目标名贵经济树种。上世纪60年代,德国医药科学家发现银杏叶片中含有治疗心脑血管动脉硬化、高血压、糖尿病等疾病的多种药效成分,再一次激发了人们种植和发展银杏这一古老树种的热情。我国银杏树拥有量占世界总量的70%以上,居世界第一位,遍布全国27个省、市、自治区,每年以2000~2500万株的速度递增。银杏属落叶树,我国每年自然产银杏叶约30万t,除3万t定向栽培的银杏叶用于药物提取外,大部分随自然落叶流失。利用银杏叶栽培食用菌,既可减少我国用于食用菌栽培的林木消耗量,又可达到这一宝贵资源的充分合理地应 Ginkgo biloba is one of the oldest and rare species in the world, and it is also a multi-target and precious economic species. In the 1960s, German medical scientists found that Ginkgo biloba contains various medicinal ingredients for curing cardiovascular and cerebrovascular arteriosclerosis, hypertension, diabetes and other diseases, and once again stimulated people’s enthusiasm for planting and developing the ancient species of ginkgo. China’s ginkgo tree possesses more than 70% of the world’s total, ranking the first in the world and spreading throughout 27 provinces, municipalities and autonomous regions nationwide, with an annual increase of 2,000-25 million. Ginkgo deciduous trees, our country each year naturally produce Ginkgo biloba about 300000 t, in addition to 30000 t directional cultivation of Ginkgo biloba for drug extraction, most of the loss with the natural deciduous. The use of ginkgo leaf cultivation of edible mushrooms can reduce the consumption of forest trees for cultivation of edible mushrooms in our country, but also to achieve the full and reasonable
