| To explore the effects of maize sowing density under the maize-Aconiti Lateralis Radix Praeparata intercropping pattern on the yields of maize and Aconiti Lateralis Radix Praeparata and the growth environment of Aconiti Lateralis Radix Praeparata, five treatments with maize densities of 500 plants/667 m2, 1 000 plants/667 m2, 1 500 plants/667 m2, 2 000 plants/667 m2, and 2 500 plants/667 m2 were established, with monocropped Aconiti Lateralis Radix Praeparata as the control. A randomized block design was adopted, and the light, temperature, and humidity conditions, yield, and economic benefits of Aconiti Lateralis Radix Praeparata were measured. The results showed that under Treatment 2 (1 000 plants/667 m2), the yield of Aconiti Lateralis Radix Praeparata reached 775.39 kg/667 m2, the maize yield reached 208.44 kg/667 m2, and the economic benefit was 8 254.16 yuan/667 m2, which was 7.34% higher than that of monocropped Aconiti Lateralis Radix Praeparata. Under Treatments 4 and 5, maize yield increased, whereas the yield of Aconiti Lateralis Radix Praeparata decreased, and the economic benefits also decreased.Comprehensive analysis showed that different maize planting densities could effectively regulate light distribution within the canopy of Aconiti Lateralis Radix Praeparata and soil temperature and humidity, thereby significantly affecting the growth of Aconiti Lateralis Radix Praeparata. Optimizing the density configuration can significantly improve the comprehensive benefits of the intercropping system. |
