摘要
为了探索适宜不同立地条件的栎类树种直播造林技术,笔者以栓皮栎与辽东栎为试验树种,研究了在不同立地条件下,播种季节、播种深度、整地方式、围栏保护对直播造林成活与生长的影响。结果表明,辽东栎直播造林适宜于阴坡上进行秋播,采取水平沟整地方式和围栏保护措施能显著提高直播造林成活率和生长量;栓皮栎直播造林最适宜的立地类型为阴坡上坡位,播种深度以浅播(3 cm~5 cm)为宜;影响辽东栎与栓皮栎直播造林效果的主要限制因子是土壤水分和土壤温度。
In order to explore suitable direct seeding afforestation of the oak tree species for different site conditions,the effects of sowing season,sowing depth,field preparation and fence protection on the survival and growth of direct seeding afforestation under different site conditions were studied.The results showed that direct seeding afforestation of Quercus liaotungensis was suitable for autumn sowing on the shady slope,and the survival rate and growth rate could be improved significantly by adopting horizontal furrow preparation and fence protection measures.The most suitable site type for direct seeding afforestation of Quercus variabilis was the uphill position of shade slope and the seeding depth was suitable for 3 cm~5 cm.Soil moisture condition and soil temperature were the main limiting factors to direct seeding afforestation of Quercus liaotungensis and Quercus variabilis.
