摘要
４年田间试验结果表明：油莱对硼锌的吸收以开花、成熟期最高．分别占全生育期的５２．０％和４０．４％，锰的吸收各期基本均衡，苗期＋薹喷施较拌种显著增产．喷０．１％～０．２５％硼砂溶液，均显著增产，苗期和苗期＋薹期＋初花期喷施效果最好，硼锌配合的产量最高，但与单独施用无显著差异。
The field experiment in four years showed that the greatest amounts of B and Zn absorbed were in flowering and reipening periods with 52.0% and 40.4% of total uptake in whole growth respectively, while the absorbed amount of Mn was even in whole growth period ,Spraying B at seening and bolting stages markedly increased yield, and the suitable cocentration of B was 0.1%～0.25%. it seemed that the best stages .With the use of B and Zn , the maximum yield was produced, but that was no significant difference to the use either B ofr Zn.
