【摘要】 本试验采用盆栽试验研究光照、水分与硼对生长发育和产量的影响,明确不同气候条件与硼对大豆的作用.结果表明:相同硼供给水平下,大豆株高随光照减弱而增高;施硼缓解涝胁迫;相同硼供给水平下,光照减弱导致大豆干物重降低;成熟期正常水分处理的干重高于淹水处理;施硼能够增加单株荚数、粒数、粒重.更多还原

【Abstract】 Experiments were conducted to investigate effects of different illumination,soil moistures and boron on the growth and yield of soybean by pot cultured.Experimental results showed that under the same B supplying,with the decreasing of the intensity of illumination,the height of the soybean was increased;and exerting B can alleviate the water stress.The decreasing of the intensity of illumination reduced the accumulation of dry matter of the soybean under the same level of B supplying.During the mature period,as for the dry matter,the normal water was higher than the flooding stress treatment;and exerting B can increase the number of pods and seeds and the weight of seeds per plant.更多还原
