摘　　要：元宝枫蛋白桑混交林是榆林市近年来推广的栽培模式。本研究测定了3种混交栽植模式的蛋白桑生长量以及光合有效辐射值,并分析了蛋白桑生长量与光合有效辐射的关联性。结果表明,随着元宝枫栽植行距的加大,蛋白桑获得的光合有效辐射值就随之变大,且蛋白桑的干物质产出量也随之增加,在混交林中,光合有效辐射的分配差异是蛋白桑生长量差异的主要原因,建议采用元宝枫株行距2 m×4 m,行间套种3行蛋白桑,蛋白桑株行距0.3 m×0.8 m的栽植模式。研究结果对于元宝枫、蛋白桑混交模式优化配置具有一定参考价值。The mixed forest of Acer truncatum and Morusalba has been promoted as a cultivation model in Yulin City in recent years.This study measured the growth parameters of Morusalba and photosynthetic active radiation(PAR)values under three mixed planting patterns,analyzing the correlation between Morusalba growth and PAR.Results showed that as the row spacing of Acer truncatum increased,both the PAR obtained by Morusalba and its dry matter production correspondingly increased.The distribution variation of PAR in mixed forests was identified as the primary factor causing growth differences in Morusalba.The recommended planting pattern involves Acer truncatumarranged at 2 m×4 m spacing with three rows of Morusalba(0.3 m×0.8 m spacing)intercropped between the rows.These findings provide valuable references for optimizing the mixed cultivation configuration of Acer truncatum and Morusalba.
