摘要：

通过设置不同的间作行距（30、40、50 cm）和根系分隔处理，研究间作花生对木薯叶片的碳氮代谢产物及相关酶活性的影响。结果表明，40 cm行距间作花生可提高木薯的蔗糖磷酸合成酶（SPS）、蔗糖合成酶（SS）活性及可溶性糖含量；间作花生后，木薯的氨基酸和可溶性蛋白质含量随着行距变窄而降低；相反，硝酸还原酶（NR）活性则显著增强。相同行距处理下，无根隔处理的氨基酸、蛋白质含量及SPS、SS、谷氨酰胺合成酶（GS）活性均高于根隔处理，说明木薯和花生的根系之间存在一定的相互作用。总体而言，适宜的间作行距可以提高碳氮代谢酶活性，从而促进碳水化合物和蛋白质的积累与运转，对提高木薯的产量和品质具有重要意义。

Abstract:

In this study, products and key enzyme activities of carbon-nitrogen metabolism of cassava leaf were investigated under the different interplanting row spacing (30, 40, 50 cm) and root system separation treatment. The results indicated that 40 cm row spacing interplanting peanut might enhance the sucrose phosphate synthase (SPS), sucrose synthase (SS) activity and the soluble sugar content of cassava. After interplanting peanut, amino acid and the soluble protein contents of cassava reduced with decreasing of the row spacing. On the contrary, nitrate reductase (NR) activity significantly increased. In the same row spacing, the amino acid, the protein content and SPS, SS, glutamine synthase (GS) activity of cassava without separating root were higher than separating root treatment, there were interaction in root system between cassava and peanut. In a word, the suitable interplanting row spacing might raise the key enzyme activities of carbon and nitrogen metabolism, and then the promoting accumulation and the translocation of carbohydrate and the protein, so it had important significance for increasing yield and quality of cassava.
