摘要：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.
