摘要
泡桐进入农田,使风沙区农田生态环境得到改善,从而提高农田生态系统的自我调节能力,增强对自然灾害特别是干热风的抗御能力,促使小麦稳产高产,对此已有广泛的报道;然而泡桐对麦田土壤水分和盐分以及对小麦生长发育的影响动态,尚未见系统报道,这正是泡桐改善农田生态环境,保障小麦高产稳产的有力论据。
Data were obtained for wheat growth and development and soil water and salt contents in paulownia-wheat intercropping field. It was indicated that paulownia could reduce the moisture losses from the topsoil of sheltered fields,ameliorate farmland site-conditions and increase wheat production by 6.15—9.25%. The intercropping of paulownia and wheat is profitable to the windy-sandy areas and well-irrigation areas of China.
