Abstract:

【Objective】The aim of this study was to reveal the light environment change law of soybean canopy under different planting densities in maize-soybean strip intercropping, and to clarify the effects of density on leaf photosynthetic characteristics, yield and stem lodging resistance of soybean, so as to provide the theoretical reference for the construction of reasonable population density of intercropped soybean in low radiation area. 【Method】In this study, soybean genotype of Chuandou-16 and maize genotype of Zhenghong-505 were used as experimental materials. The two-factor random expulsion design was adopted, among which maize-soybean strip intercropping and monocropping were the main factors, and three planting densities of soybean (PD1 = 17 plants/m2, PD2 = 20 plants/m2, PD3 = 25 plants/m2) were the secondary factors. Effects of planting density on light environment of canopy, photosynthetic characteristics, growth dynamics, lodging percentage and yield composition of soybean were investigated. 【Result】Two-year data showed that the growth of soybean was affected by the shading of maize and self-shade at the middle and later stages in the maize-soybean strip intercropping system. The photosynthetic active radiation (PAR) in the canopy of the plant population, leaf area index (LAI), leaf photosynthetic capacity, number of branches and yield were significantly decreased, while the degree of being affected by maize varied with soybean planting densities. In the strip intercropping, compared with PD3, the PAR in soybean population canopy of PD1 and PD2 increased by 45.4% and 24.8% respectively, the Pn of leaves increased by 46.1% and 12.3%, respectively, the Ep increased by 53.2% and 27.2%, respectively, the Bn increased by 270.4% and 140.9%, respectively, and the lodging percentage decreased by 50.3% and 19.3%, respectively. Correlation analysis showed that lodging percentage was significantly negatively correlated with the PAR, net photosynthetic rate (Pn), stem bending force (SBF), dry weight of stem / leaf ratio (S﹕L), number of branches per plant (Bn) and number of effective pods per plant (Ep), and positively correlated with plant height (PH), LAI and number of ineffective pods per plant (nEp). 【Conclusion】Therefore, in the maize-soybean strip intercropping, the appropriate planting density (20 plants/m2) was beneficial to create a better light environment of soybean population, reduce the lodging percentage, increase the accumulation of photosynthates, and thus improve the yield of soybean.
