摘要: 以核桃/小麦/欧李、核桃/小麦、核桃/山药3 种间作模式为研究对象,调查不同间作模式下的田间小气候及一年生核桃幼苗的SPAD、根系发育及幼苗成活率,旨在了解直播建园核桃幼苗生长动态。结果表明:3 种间作模式中,核桃/小麦模式的温度最高(32.91℃),核桃/山药模式的相对湿度最高(69.31%),核桃/小麦/欧李模式的田间光照强度(7068 lx)、根系发育个数(48 个)及幼苗成活率(75.8%)最高。核桃/小麦/欧李模式的核桃幼苗生长状况优于其他2种间作模式,为最优模式。

Abstract: Aiming to figure out the growth status of walnut seedlings under different intercropping patterns in direct-seeding walnut orchard, the interspecific intercropping patterns of walnut-wheat-ouli, walnuts-wheat, walnut-wheat-yam were used to investigate the field microclimate and the SPAD, root development and seedling survival rate of annual walnut seedlings. The results showed that the walnuts-wheat pattern had the highest temperature (32.91℃), the walnut-yam pattern had the highest relative humidity (69.31%) while the field intensity (7068 lx), number of root development (48) and seedling survival rate (75.8%) of the walnut-wheat-ouli pattern were the highest among three intercropping patterns. Walnut-wheat-ouli might be the optimal pattern since its seedling growth was better than the other two intercropping patterns.
