Abstract:

To screen out the best proportion of maize and cabbage interplanting and improve the theoretical basis of interplanting cultivation technology popularization and application, based on field test data of maize interplanting cabbage, we compared the yield traits and economic benefits, and evaluated the advantages and disadvantages of five interplanting modes by principal component analysis. The results showed that the comprehensive benefits of different maize/cabbage interplanting modes were mainly determined by maize yield traits, cabbage yield traits and economic benefits of different interplanting modes. The comprehensive comparison results of different interplanting modes were as follows: treatment 3 > treatment 1 > treatment 4 > treatment 2 > treatment 5. Under treatment 3 (maize density 67500 plants/hm², cabbage density 60000 plants/hm²), the yield of maize and cabbage was 12150 and 80242.5 kg/hm², respectively, and the total output value was 83634.0 yuan/hm². The benefit was higher than other treatments, and the field configuration was the most reasonable, which was the best combination mode. The study optimized the planting mode, which could increase the yield and output value per unit area, and raise the income of farmers.

Key words: Interplanting Mode, Agronomic Traits, Yield Benefit, Economic Benefit, Principal Component Analysis
