摘要:: 以葡萄和镉超富集植物龙葵为试材，采用盆栽试验，在镉污染条件下研究了葡萄混种不同密度龙葵（株行距分别为40 cm×80 cm、40 cm×40 cm、20 cm×40 cm和20 cm×20 cm）对二者碳氮代谢的影响，以期为葡萄生产提供参考依据。结果表明：40 cm×40 cm、20 cm×40 cm和20 cm×20 cm处理降低了葡萄淀粉含量，分别较单种降低了27.03%、31.22%和28.30%；20 cm×40 cm和20 cm×20 cm处理降低了葡萄可溶性糖含量，分别较单种降低了9.27%和11.71%。不同混种密度对葡萄蔗糖合成酶和蔗糖磷酸合成酶活性表现出提高、降低或无显著影响的作用。随混种密度的增大，葡萄全氮含量和谷氨酰胺合成酶活性呈降低的趋势，但混种对葡萄可溶性蛋白质含量和硝酸还原酶活性没有显著影响。就龙葵而言，混种在一定程度上提高了龙葵淀粉含量、可溶性糖含量、蔗糖合成酶活性和蔗糖磷酸合成酶活性，且龙葵全氮含量、谷氨酰胺合成酶活性和硝酸还原酶活性随混种密度的增大呈增加的趋势。因此，镉污染土壤条件下葡萄混种龙葵能够调控二者的碳氮重新分配，有助于提高二者的抗性。

Abstract:: Taking grape and cadmium (Cd) hyperaccumulator Solanum nigrum as the test materials,pot experiment was used,the effects of intercropping grape with S.nigrum at different densities (with row spacing×plant spacing of 40 cm×80 cm，40 cm×40 cm，20 cm×40 cm，and 20 cm×20 cm) on their carbon and nitrogen metabolism under Cd-contaminated conditions were studied，in order to provide references for grape production.The results showed that the treatments with 40 cm×40 cm，20 cm×40 cm，and 20 cm×20 cm decreased the starch content in grape by 27.03%，31.22%，and 28.30%，respectively，compared with monoculture of grape.The treatments with 20 cm×40 cm and 20 cm×20 cm decreased the soluble sugar content in grape by 9.27% and 11.71%，respectively，compared with monoculture of grape.Different intercropping densities had effects of increasing，decreasing，or no significant effect on the activities of sucrose synthase (SS) and sucrose phosphate synthase (SPS) in grape.With the increase of intercropping density，the total nitrogen content and glutamine synthetase (GS) activity of grape showed a decreasing trend，but intercropping had no significant effect on the soluble protein content and nitrate reductase (NR) activity of grape.For S.nigrum，intercropping increased its starch content，soluble sugar content，SS activity，and SPS activity to a certain extent.Moreover，the total nitrogen content，GS activity，and NR activity of S.nigrum showed an increasing trend with the increase of intercropping density.Therefore，intercropping grape with S.nigrum under Cd-contaminated soil can regulate the redistribution of carbon and nitrogen，which helps to improve their resistance.
