几个乡土树种生物学生态学特性及育苗技术研究

Bioecological Characteristics of Several Local Tree Species and Technology of Seedling Breeding

对臭椿、酸枣、荆条、山桃、毛樱桃、黄刺玫、柄扁桃、细叶小檗等乡土树种的自然分布、立地条件和生物学生态学特性作了研究,并收集播种材料进行育苗试验。研究表明:上述树种的生物学、生态学特性对于其分布区内水土保持、水源涵养及防护林营建的树种选择有积极的意义和可行性;试验树种在保证播种品质的前提下,核果及瘦果类种子低温层积沙藏处理时间的长短是其育苗的关键技术。

Natural distribution, site condition and bioecological characteristics of some local tree species have been studied in this paper. The result shows: bioecological characteristics of these tree species can help to choose tree species for planting protective forest in their distributing area. The length of seeds of drupe and achene stored in lowtemperature sand is the key technology of breeding seedlings.
