摘要
该试验于2008-2009年和2009-2010年在孟加拉国巴布纳Ishurdi的孟加拉国甘蔗研究所(BSRI)农场进行，目的是调查主要作物甘蔗的生长和产量，以及作为连作间作的伴生作物马铃薯和绿豆。甘蔗行距(RRS)分别为80 (s1)、100 (s2)和120 cm (s3)，甘蔗间作1行、2行和3行马铃薯，其次间作绿豆，行比相同。甘蔗及其伴生作物马铃薯和绿豆分别按照BSRI和孟加拉国农业研究所(BARI)的栽培方法进行栽培。为了给间作提供更多的光照，对甘蔗行两侧的弯曲叶片进行了中间切叶，并对主粮和间作的生长和产量进行了与不切叶的比较。甘蔗(不切叶= c0)间作3行马铃薯后再间作3行绿豆(s3 c0)，总干物质产量、甘蔗产量和糖产量在120 cm RRS时最高。甘蔗(c0)与一排马铃薯和一排绿豆(s1c0)在80 cm RRS时分蘖和可分茎数和叶面积指数(LAI)最高。截光对第一间作马铃薯生长和产量的影响不显著，而对第二间作有显著影响。绿豆(第2间作)产量和截光比(%)在甘蔗RRS为120 cm + 3r马铃薯的s3c - 1中最低，然后是3r绿豆切叶(LC)。试验结果表明，甘蔗按RRS 120 cm移栽，3行马铃薯后3行绿豆可作为间作种植，既可提高甘蔗产量，又可提高种植强度，可推荐用于孟加拉国第11经济区的恒河高洪泛区土壤的农民实践。农业学家2016;14 (2) 67 - 76
Successive Intercropping of Potato and Mungbean with Sugarcane
The experiment was carried out at the Bangladesh Sugarcane Research Institute (BSRI) farm at Ishurdi, Pabna, Bangladesh during2008-2009 and 2009-2010to investigate the growth and yield of main crop sugarcane, and companion crops potato and mungbean as successive intercrops. Row to row spacing (RRS) of sugarcane were 80 (S 1 ), 100 (S 2 ) and 120 cm (S 3 ) and sugarcane was intercropped with 1, 2 and 3 rows of potato as 1st intercrop and followed by mungbean with same row ratio as 2 nd intercrop. Sugarcane and companion crops potato and mungbean were cultivated following the cultivation methods of BSRI and Bangladesh Agricultural Research Institute (BARI), respectively. To provide more light to intercrops bended leaves of sugarcane on both sides of rows were cut at middle and compared with non-cutting of leaves in respect of growth and yield of main crop and intercrops as well. The total dry matter production, cane yield and sugar yield were the highest at 120 cm RRS of sugarcane (non-leaf cutting=C 0 ) intercropped with 3 rows of potato followed by 3 rows of mungbean (S 3 C 0 ). The number of tiller and millable canes, and leaf area index (LAI) were the highest at 80 cm RRS of sugarcane (C 0 ) with one row of potato and one row of mungbean (S 1 C 0 ). The effect of light interception on growth and yield of first intercrop (potato) was insignificant whereas it was significant for second intercrop. Yield of mungbean (2 nd intercrop) and light interception ratio (%) was the lowest in S 3 C 1 where sugarcane RRS was 120 cm + 3 R potato followed by 3 R mungbean with leaf cutting (LC). The results of the experiment indicated that sugarcane transplanted at RRS of 120 cm with 3 rows of potato followed by 3 rows of mungbean can be grown as intercrops for increased yield of sugarcane as well as for increased cropping intensity and might be recommended for farmers practice in High Ganges River Flood Plain soils under AEZ 11 of Bangladesh.
