Effects of Intercropping Patterns on Dry Matter Accumulation and Transportation of Maize (Zea mays L.) and Soybean [Glycine max (L.) Merrill]

[Objective] The aim was to discuss the group dry matter accumulation and economic benefits under the patterns of intercropping maize with soybean. [Method]Zhengdan-958 and Luhuang-1 were used as the testing breeds to study the intercropping patterns on dry matter accumulation and transportation of maize and soybean in Huang-huai-hai. [Result] The results showed that dry matter accumulation amount per hectare of intercropping was significantly higher than that of the monoculture patterns of maize,especially after silking. The dry matter accumulation amount of monoculture were significantly higher than that of the intercropping patterns of soybean before and after flowering. The dry matter translocation amount of monoculture were significantly or very significantly higher than that of intercropping. The transfer rates were0. 59% and 4. 74% respectively of maize and soybean's intercropping than monoculture. The dry matter accumulation were fitted with Logistic equation,and maximum dry matter accumulation rate reached significant level between monoculture and intercropping of maize. Maximum,appearance and duration of dry matter accumulation rate reached the extremely significant level between monoculture and intercropping of soybean. Land equivalent ratio of intercropping was1. 30. From yield and output value,The yield of intercropping were 10. 97 t / hm2,and0. 64% and 326. 85% higher respectively compared with monoculture of maize and soybean. The intercropping of total output value was25 796. 23 CNY per ha,and 12. 67% and 12. 67% higher than that of maize and soybean's monoculture. [Conclusion]The study lays a basis for improving grain yield and economic benefits.
