- Abstract
In this study, products and key enzyme activity of carbon-nitrogen metabolism of peanut leaf were investigated under the different intercopping row spacing ( 30, 40, 50 cm) and root system separation treatment. The result indicated that cassava-peanut intercropping made the soluble sugar content, amino acid content, the the sucrose phosphate synthase ( SPS ), sucrose synthase ( SS) activity and nitrate re d uctase ( NR ), glutamine synthase ( GS) activity decrease, the suitable row intercroping treatment could increase the protein content of peanut leaf. The inhibition of row spacing on products of carbon-nitrogen metabolism, NR and GS were the most, and root system separation treatment could relieve the inhibition of carbon-nitrogen metabolism in the row spacing intercropping system, it showed that he products and key enzyme activity of carbon-nitrogen metabolism of root system separation treatment were more than non-separation treatment in 30 cm row spacing treatment. On the contrary, the products of carbon-nitrogen metabolism of root system separation treatment were lower than non-sepa ration treatment in the suitable row spacing, it showed that root interaction between cassava and peanut was different because of different intercropinng row spacing, and the root interaction in the lower intercropinng row spacing was competitive and inhibit, but the root interaction in the suitable intercropping row spacing was complementary and positive.
