通过林麦间作系统的光照条件和小麦生物量的平行观测，分析淮北地区三种杨树种植密度林麦系统的光照分布规律，以及相应小麦产量表现。得出４ｍ ×２４ｍ 的密度林麦系统，小麦千粒重和产量较高，是较佳的农林立体栽培方式。
The light distribution of three poplar planting density ramet systems in Huaibei area and the yield performance of the corresponding wheat were analyzed through the light and wheat biomass in the intercropping system. The results showed that the 4m × 24m density Linmei system had higher grain yield per plant and 1000-grain weight, which was the better way of three-dimensional cultivation in agriculture and forestry.
