摘要
以高蛋白大豆东农42为材料,采用大田试验研究生物肥的施用对大豆株高、根长及产量的影响。试验结果表明:生物有机肥的施用对大豆植株生长有促进作用。生物肥总体上在各个时期都促进大豆植株生长。但对大豆植株生长的影响在苗期、盛花期、鼓粒期体现不明显,而主要体现在成熟期,在成熟期施用生物肥的大豆株高明显高于对照。
Taking high protein soybean Dongnong 42 as materials, field experiment was conducted to study effect of organic bio-fertilizer on biological characteristics and yield of soybean. The results showed： Using organic biofertilizer could promote plant height of soybean, But the effect wasn＇t obviously in seeding stage and blossom stage, it was especially obviously in mature stage.
