地膜复盖育苗是一种先进的保护性栽培技术,已在我国农业生产上推广运用。特别在干旱寒冷的北方,地膜复盖在蔬莱生产上的运用更为广泛,取得了明显的经济效益。但地膜复盖技术在林业育苗生产上运用,至今还少见系统报道。本项研究通过对意大利杨树的4个品种(Ⅰ—63/50、Ⅰ—69/55、Ⅰ—72/58、Ⅰ—214)地膜复盖育苗和常规大田育苗对比试验,探索地膜复盖在林业育苗生产上的运用途径及可能产生的经济效益,为在林业生产上推广运用提供依据。
Mulch is a kind of advanced protective cultivation technology, which has been popularized and applied in China’s agricultural production. Especially in arid and cold northern areas, the application of plastic film mulching in the production of vegetables is more extensive and obvious economic benefits have been achieved. However, the use of plastic film mulching technology in forestry nursery production is still rare in the system. In this study, we compared the plastic film mulching and conventional field nursery experiments of four poplar varieties (Ⅰ-63/50, Ⅰ-69/55, Ⅰ-72/58 and Ⅰ-214) The application of forestry seedling production methods and the possible economic benefits provide the basis for the promotion and application of forestry production.
