人工林生态系统的林术营养规律研究应从遗传、生境和栽培管理三个方面入手。以往对杉木人工林生态系统林木营养的研究较少,随着经营集约度的提高,采用施肥等措施改善杉木林分的营养状况将成为杉木经营的方向。因此对杉术人工林的营养特性应有较深刻的了解。另一方面,杉木的遗传因素相对稳定,限于现有的生产水平,只能选择良好的营养生境栽培杉木人工林,而辅之人工栽培管理措施。所以应在了解各种生态因子对杉木营养的影响基础上发挥杉木不同种源、类型和无性系的营养遗传潜力。
Plantation ecosystem ecosystem law of forestry should be from the genetic, habitat and cultivation and management of three aspects. In the past, there were few studies on plantation nutrition of Cunninghamia lanceolata plantation ecosystem. With the improvement of operation intensiveness, the application of fertilizers and other measures to improve the nutritional status of Chinese fir plantation would be the direction of Chinese fir plantation. Therefore, the nutritional characteristics of Cunninghamia lanceolata plantation should have a more profound understanding. On the other hand, Cunninghamia lanceolata genetic factors are relatively stable, limited to the existing level of production, can only choose a good vegetative habitat Cunninghamia lanceolata plantation, supplemented by artificial cultivation management measures. Therefore, we should understand the impact of various ecological factors on Chinese fir nutrition and exert the nutritional genetic potential of different provenances, types and clones of Chinese fir.
