不同栽培方式对大豆产量及构成因子的影响

摘要

In order to improve the soybean yield ,two kinds of cultivation patterns were set up ,and the effects of narrow row close planting cultivation of 45 cm ,conventional ridge cultivation pattern of 65 cm on soybean yield and component factors were studied ,and the economic income of two cultivation patterns were analyzed .The results showed that the pods per plant ,seeds per plant and the seeds per pod of Heihe 36 under conventional ridge cultivation pattern were more than those of Henong 60 under narrow row close planting cultivation .The yield of Henong 60 under narrow row close planting cultivation was 3 615 kg·hm-2 which was higher than Heihe36 under conventional ridge cultivation pattern ,and the yield of Heihe 36 was 2 865 kg·hm-2 .The differ-ence between the two cultivation patterns was greatly significant ,and the yield of narrow row close planting cultivation pattern was higher than conventional ridge cultivation pattern by 750 kg·hm-2 ,the yield grow th rate was 26 .17% and the increase income was 3 000 yuan·hm-2 .%为了提高大豆产量，试验设置2种配套栽培模式处理，研究45 cm窄行密植栽培模式和65 cm垄作栽培模式对大豆产量及其构成因子的影响，并对经济效益进行分析。结果表明：垄作栽培下，黑河36的株荚数、株粒数、荚粒数均高于窄行密植栽培模式下的合农60。合农60窄行密植栽培模式产量为3615 kg · hm-2，黑河36垄作栽培模式产量为2865 kg·hm-2，2种栽培模式下产量差异达到极显著水平。窄行密植栽培模式较垄作栽培模式增产750 kg·hm-2，增产率达到26．18％，增收效益为3000元·hm-2。
