摘　　要：本试验采用盆栽试验研究不同水分和硼对大豆农艺性状和产量的影响.研究表明:水分对大豆株高和干物重影响显著;硼对大豆株高和干物重影响不显著;水分与硼互作对大豆株高和干物重影响也不显著.在水分胁迫时,施硼显著影响大豆产量构成因子的形成.干旱胁迫施硼无效;偏涝时,施硼能显著增加大豆单株荚数、单株粒数和单株产量.In order to study the influences of the different soil moistures and the boron on the agricultural characters and yield of soybean,the potted plants conducted the research experiments. Experimental results showed that soil moisture affected on the height and yield of the soybean significantly, but boron and the interaction of soil moistures did not affect the height and yield of the soybean so significantly. Boron benefits in forming factors of yield for soybean under the stress of soil moisture. When drought, tbe application of boron was not effective in forming factors of yield of soybean. Under the condition of soil moistures logging,the application of boron could increase pods,seed numbers arid yield of soybean.
