落叶松是阳性树种,生长很快,对气候、土壤条件要求不严。由于幼苗期不耐高温和强光照射,过去采用遮阴育苗。这虽保证了产苗量,但育苗成本高,苗木细弱、质量差、造林成活率低。为了克服这些矛盾,我们采取了全光育苗办法,几年来,不仅育苗成本低、苗木质量高,而且保证了产苗量。 Larch is a positive species, grow rapidly, the weather, soil conditions, lax requirements. As the seedling is not high temperature and strong light exposure, the use of shade nursery. Although this ensures that the amount of seedlings, but the high cost of nursery stock, thin seedlings, poor quality, afforestation survival rate is low. In order to overcome these contradictions, we have adopted the all-photo nursery method. In recent years, not only the cost of nursery is low, the quality of nursery stock is high, but also the quantity of seedling produced is guaranteed.
