针叶树(主要是油松、落叶松、樟子松)是我区造林的主要树种。培育优质、高产的针叶树苗,对于改变我区造林树种的组成,提高造林质量,加快绿化步伐,具有重大意义。培育针叶树苗,除了选择良种、细致整地、精心播种外,加强苗期的科学管理是关键。针叶树的苗期管理,主要是根据苗木的生物学特性、生长规律和苗圃的气候、土壤等条件,进行合理灌溉、及时松土除草、合理追肥、适时间苗以及加强病虫害防治等工作。下面根据我区培育针叶树苗木的经验,对针叶树苗期管理,谈几点意见。
Conifers (mainly Pinus tabulaeformis, larch, Pinus sylvestris) is the main afforestation species in our area. Cultivating high-quality and high-yield coniferous saplings is of great significance for changing the composition of afforestation tree species in our area, improving the afforestation quality and accelerating the pace of afforestation. Cultivation of coniferous saplings, in addition to the selection of seed, meticulous land preparation, careful sowing, strengthening the scientific management of seedling is the key. Conifer seedlings management, mainly according to the biological characteristics of seedlings, growth and nursery climate, soil and other conditions, reasonable irrigation, timely loosening weeding, reasonable top dressing, timely seedling and pest control and other work to strengthen. The following area based on my experience in breeding conifer seedlings, coniferous tree seedling management, talk a few comments.
