摘要
为比较银杏和石楠的竞争能力和适应能力,围绕同一地区同一年份生长的银杏石楠的碳含量、氮含量、热值、灰分值,单位面积构成成本和单位质量构成成本等内容展开了实验。结果表明:同一地区同一年份生长的银杏和石楠,银杏的氮含量高于石楠,石楠的灰分含量、碳含量、单位面积建成成本、单位面积建成成本、单位质量建成成本高于银杏。石楠具有更高的叶片建成成本,所以石楠的碳资源利用率更低,银杏的叶片建成成本更低,故能够将更多的能量投资到竞争策略中,这可能是银杏分布范围更广,更占据优势的原因之一。综合考虑,相比石楠,银杏更适合种植,此外银杏还有很多作用,可以祛痰止咳、降血压、降低血液粘稠度等作用。因此相比石楠,银杏更适合种植,更能充分利用资源,有着保护环境节约资源的重要意义。
This experiment mainly focused on the carbon content,nitrogen content,calorific value,ash content,unit area composition cost and unit mass composition cost of Ginkgo biloba and Photinia serrulata growing in the same year in the same area.The purpose is to compare the competitiveness and adaptability of G.biloba and P.serrulata.The experimental results show that G.biloba growing in the same area in the same year have higher nitrogen content than P.serrulata.The ash content,carbon content,unit area construction cost,unit area construction cost,and unit quality construction cost of P.serrulata are higher than G.biloba.P.serrulata has a higher leaf construction cost,so P.serrulata has a lower carbon resource utilization rate.G.biloba has a lower leaf construction cost,so it may be able to invest more energy in the competition strategy,which may be one of the reasons why G.biloba is more widely distributed and dominant.In general,compared with heather,Ginkgo biloba is more suitable for planting.In addition,Ginkgo biloba has many functions,such as expectorant,cough relieving,blood pressure lowering,blood viscosity lowering,etc.Therefore,compared with Photinia serrulata,Ginkgo biloba is more suitable for planting and can make full use of resources,which is of great significance to protect the environment and save resources.
