Pot experiments were conducted to investigate the nitrogen (N) uptake of grape seedlings by intercropping and straw applying of Pterocypsela laciniata. The results showed that five treatments: the monoculture of grape, grape intercropping with P. laciniata , the root straw of P. laciniata applied, the stem straw of P. laciniata applied and the leaf straw of P. laciniata applied. All treatments significantly increased the content of total N in grape roots, leaves and shoots of grape seedlings. The straw applying significantly increased the content of total N in grape stems, and the stem straw of P. laciniata had the greatest effect on promoting N uptake of grape. When the stem straw of P. laciniata was applied, the soil alkali solution N content was increased by 9.93%. Therefore, applying stem straw of P. laciniata can not only promote N uptake by grape but also increase soil alkali solution N content.
