【摘要】 为了探讨桐粮间作生态模式的生态效应,本研究进行了桐粮间作与单作粮试验对比分析。结果表明,桐粮间作区比单作粮区能充分利用光照、积温、水资源、土壤养分,且对空气温湿度具有调节作用。桐树‖小麦—大豆间作比小麦—大豆单作粮模式光能利用率提高0.49%;空气温度冬季提高0.2～1.6℃、夏季减低0.3～1.1℃;空气相对湿度提高2%～7%,且能充分利用水资源和具有防风固沙作用。更多还原

【Abstract】 In order to study the ecological effects of intercropping paulownia and crops,the comparative experiment were conducted between paulownia & crops intercropping and crops sole cropping.The results showed that intercropping could make full use of light,cumulative temperature,water and soil nutrition,and could adjust air temperature and humidity.Intercropping paulownia and crops could raise light utilization efficiency by 0.49 %,air temperature 0.2-1.6 ℃ in winter,relative humidity 2 %-7 %,lower temperature by 0.3-1.1 ℃ in summer,and could more fully make use of water and function as windbreak and sand dune fixation.更多还原
