| In this study, field experiments were conducted to elucidate the population of weeds, soil nutrient, crop
yield and land equivalent ratio (LER) under sugarcane monoculture, soybean monoculture and sugarcane/soybean
intercropping patterns. Results showed that the amount of weeds was 16.5 to 25.0 plant per m2 under sugarcane/soybean
intercropping pattern while 40.0 to 45.0 plant per m2 under sugarcane monoculture, reduced significantly under sugarcane/
soybean intercropping pattern. Furthermore, the values of the tatol N, tatol P, available K and available P increased by 0.03
g/kg 0.058 g/kg 0.1344 mg/kg and 5.34 mg/kg respectively, shouing that some of the soil nutrients was improved under
intercropping pattern. The sugarcane seedling emergence and cane yield had no significant difference between sugarcane
monoculture and sugarcane/soybean intercropping pattern. Finally, the LER of the intercropping pattern was high as 1.39-
1.63, which meant that intercroping pattern had stronger intercropping advantages. |
