Abstract:

Crop intercropping system in arid areas is an important planting method for optimizing crop population quality and improving crop yield. There are few reports on the mechanism of crop intercropping competitive advantage in terms of yield components. In this study, to explore the mechanism of crop competition for increasing the yield of intercropping systems, three soybean densities and four row proportions (maize and soybean intercropping with 2:0, 0:2, 2:2, and 2:4) were used to investigate the changes of competition index, yield components, and yield of intercropping system. The results showed that the yield of intercropping system with different row proportion and soybean density was increased by 14%-23%. The actual yield loss of maize was greater than 0, the actual yield loss of soybean was less than 0. The ear weight, ear length, ear diameter, grain weight per ear, cob weight, and 1000-grain weight of maize in intercropping systems were significantly higher than those in monoculture. Except pod length and internode length of main stem, the grain weight per plant, pod number per plants, grain number per plant, effective grain number per plants, nodes on main stem, and 100-grain weight of soybean in intercropping systems were lower than that of monoculture. And there was no significant difference between intercropping and monoculture. The competition ratio of maize was greater than one, and the competition ratio of soybean was less than one. The competition ratio of maize and soybean was 2.08, 1.84, 1.68 and 0.49, 0.56, 0.63, respectively, with three soybean densities, indicating that with the increase of soybean density competition ratio of maize increased while competition ratio of soybean decreased in intercrops. The aggressivity of maize was positive value, and that of soybean was less than zero in intercropping system. Maize yield was positively correlated with cob weight, 1000-grain weight, ear weight, grain weight per ear, ear length, and row kernel number negatively correlated with barren tip length. Path analysis revealed that in the direct effect, grain weight per ear contributed the most to maize yield (2.18); in indirect effect, cob weight and 1000-grain weight contributed more to maize yield 1000-grain weight per ear (1.64 and 1.58). In conclusion, maize intercropped with soybean had intercropping advantages that derived from grain weight per ear.

Key words: density, intercropping, path analysis, competition ratio
