水分、光照与硼互作对大豆生长发育及产量的影响

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.

Effects of soil moisture、illumination and boron on the growth and yield of soybean

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.
