硼、钼对不同基因型大豆产量和品质的影响

Effect of boron and molybdenum on yield and quality of different genetic varieties of soybean

施硼、钼能够提高大豆的产量和蛋白质的含量。从硼、钼的作用效果看,施钼处理高于施硼处理,硼、钼同施有互促作用。增产幅度表现为:秣食豆>东农42>东农46。施硼、钼处理降低了两个栽培品种(东农42、东农46)籽粒中脂肪的含量,提高了半野生品种(秣食豆)的脂肪含量。同硼、钼营养水平相比,大豆自身的遗传特性对大豆籽粒的蛋白质和脂肪含量影响具有稳定性。

Appropriate application rate of B and Mo increased the yield and the protein content of soybean. From the results of effect of B and Mo, application of Mo produced a higher yield than that of B, an appropriate application rate of both B and Mo increaseed the yield, and they stimulated each other. The trend was half wild variety〉Dongnong42〉Dongnong46. Application of B and Mo lowered the fat content of grain of the two cultivars （Dongnong42 and Dongnong46）, application of either B or Mo increased the fat content of grain for the half wild variety. In comparison with the mineral nutrition, effects of the genetic characteristics on the protein content and the fat content of grain were also stable.
