间种对不同基因型甘蔗生长产量影响与经济效益分析

结合国家甘蔗技术体系试验示范要求,采用大区互比与室内分析相结合的方法,开展不同基因型甘蔗间种大豆及甘蔗不同行距间套种大豆的研究。结果表明,在试验条件下,每公顷蔗地产出干大豆978.0～2 788.5 kg,平均为1 525.5 kg/hm2,获得产值3 909.09～11 156.88元,平均产值6 128.40元/hm2,利润为1 815.97～6 975.01元,平均为3 356.29元/hm2的经济效益;不同甘蔗基因型间种相同品种的大豆,对大豆的农艺性状、生物产量和豆荚产量都有不同的影响;在甘蔗间套种大豆合理的模式条件下,间种大豆对甘蔗的生长和产量影响较少或者没明显的影响,可以取得一定的增收增效作用,但在间种不合理时也会对甘蔗生长和产量导致负向的影响,间种对不同基因型甘蔗分蘖有较大影响;2种作物的播种期安排是甘蔗间套种取得成功的关键。

Analysis of Interplanting on the Influence of Growth, Yield of Sugarcane with Various Genotypes and Its Economic Returns

With the target and contents of the National Sugarcane Industrialization Technology Research System, interplanting of soil bean with sugarcane genotypes was studied in Jinmanyuan Agricultural Demonstration Station at Tanle Town. The results showed that 978.0~2 788.5 kg/hm2, or mean yield of 1 525.5 kg/hm2, of soybean valued 3 909.09~11 156.88 RMB/hm2 with a 1 815.97~6 975.01 RMB/hm2 net profit of could be produced in this trial. There were different effects on the agronomic properties, biomass and pod output for interplanting of soybean with sugarcane genotypes. Sugarcane growing and output were not affected significantly except for tillering in this style of interplanting of soybean in the sugarcane field, while the economic profit would be increased. There would be negative effects in unreasonable interpanting of soybean style. The key success of the interplanting style would be the reasonable panting time of both crops.
