Abstract:

To investigate the effects of wheat and pea intercropping on population photosynthetic characteristics and productivity, a field experiment with two treatments [two strip cropping treatments of four rows of wheat + two rows of peas (W4P2), two rows of wheat + two rows of peas (W2P2), and single-crop wheat (CKW) and single-crop pea (CKP) as the controls] was conducted in Guanzhong region of Shaanxi Province from 2019 to 2021. The leaf photosynthetic rate (Pn), canopy apparent photosynthesis (CAP), dry matter accumulation and population productivity of wheat and pea were analyzed. The results showed that, compared with the monoculture, the W2P2 and W4P2 intercropping treatments significantly increased the SPAD and Pn of wheat leaves, but decreased the SPAD and Pn of pea leaves to different degrees. Intercropping wheat with peas significantly increased the preflowering population photosynthetic rate. The CAP of W4P2 increased by 6.2%-8.0% compared to its control population photosynthetic CAPCK42 (2/3CAPCKW+1/3CAPCKP), while the CAP of W2P2 increased 6.2%-8.5% compared to its control population photosynthetic CAPCK22 (1/2CAPCKW+1/2CAPCKP). Compared with CKW, the W4P2 and W2P2 intercropping treatments significantly enhanced the dry matter accumulation capacity per unit area of wheat, significantly increased the number of effective spikes and spikes at maturity stage, and increased the seed yield by 7.8%-9.4% and 18.9%-19.0%, respectively. Compared with CKP, the two intercropping treatments had a weakening trend in the dry matter accumulation and yield composition indexes of peas, and reduced the seed yield by 9.9%-12.2% and 6.8%-9.0%, respectively. The competitiveness evaluation revealed that the land equivalent ratios of W4P2 and W2P2 intercropping treatments were higher than 1 (W4P2: 1.02; W2P2: 1.06), indicating that wheat and pea intercropping increased the crop population yield advantage and the encroachment of the dominant crop wheat compared to pea was higher in the W2P2 intercropping model (0.27) than in W4P2 (0.20). In conclusion, in the wheat and pea intercropping system, compared to the broad-banded type (W4P2), the narrow-banded type (W2P2) was able to increase the population photosynthetic rate by increasing the photosynthetic capacity of the dominant crop wheat, thus promoting the use of light resources by the population and further exploiting the composite population production advantage.
