密集烤房不同装烟方式烘烤效果研究

    Research on productivity of the sugarcane/ soybean intercropping pattern

    • 摘要: 为了探寻适合广东烟叶烘烤生产的装烟方式,对梳式烟夹、散叶插签堆放及常规竹竿等3 种装烟方式进行对比试验。结果表明,与常规竹竿相比,梳式烟夹和散叶插签堆放设备投入成本较高,但这两种装烟方式的装烟量和装烟密度比常规竹竿大幅增加,装烟和卸烟工作效率明显提高,用工成本显著降低;在烘烤过程的能耗方面,梳式烟夹和散叶插签堆放较常规竹竿有不同程度的降低,进一步节省烘烤成本;从烤后烟叶经济性状来看,梳式烟夹的表现最好,常规竹竿和散叶插签堆放次之,因此认为梳式烟夹可进一步试验和推广。

       

      Abstract: 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.
