叶面喷施硼钼锌对大豆产量和品质的影响

研究了叶面喷施硼钼锌对大豆产量和品质的影响.结果表明:B Mo Zn配合喷施产量最高,较对照增产19.6%;2种微量元素配合喷施时,以B Mo配合最佳,其产量与B Mo Zn配合差异不显著,B Zn或Mo Zn配合仅比对照略有增产.B Mo Zn配合的每荚粒数居各处理首位,每株荚数居第2,B Mo配合的每株荚数和百粒重处于各处理首位.试验还表明,凡有配施B的处理,即B Mo、B Zn和B Mo Zn,有利于提高大豆的含油量;凡配施Zn的处理,即Mo Zn、B Zn和B Mo Zn,有利于提高大豆的蛋白质含量.对于只考虑提高其产量及含油量,以B Mo配合较好;而优质大豆的豆粕所含的蛋白质可以直接作为动物饲料,因此在提高其产量和含油量,还要兼顾其蛋白质含量,则以B Mo Zn配合效果最好.

Effects of Foliar Spraying B、Zn、Mo on the Yield and Quality in Soybean

The effect of foliar spraying B,Mo,Zn on the soybean Shangdou 1099 yield and quality was tested.Results indicated that the yield under the B Mo Zn combination treatment was the highest,which increased 19.6% comparing to the control.The B Mo combination treatment was the optimum combinacion when two micro-elements was used,and had no significant difference with that of the B Mo Zn treatment.The grains number per pod and pods number per plant of the B Mo Zn combination came to the 1st and the 2nd place.The pods num berper plant and hundred grain weight of the B Mo combination were the highest in all of the treatments.The treatment combinated with B could increase the oil content of peanut.The treatment combinated with Zn could increase the protein content of peanut.The treatment combinated with B Mo Zn could not only increase the yield and oil content,but also the protein content of peanut.
