为探讨中微量元素肥料施用的优越性,在大田条件下,以‘合丰55号’大豆为材料,设不施肥、常规施肥、中微肥处理,研究中微肥对大豆生长发育及产量的影响。结果表明:中微肥施用能够提高大豆不同生育期的株高、干物质积累量和叶绿素含量(SPAD)。与不施肥和常规施肥为对照,施用中微肥大豆增产为14.5%和4.7%。差异达到显著和极显著水平。因此,中微量元素肥料的施用对大豆生产起到积极的促进作用。
In order to discuss the superiority of application of trace element fertilizers, under the condition of field, using ’Hefeng No.55’ as the material, we set up non-fertilization, conventional fertilization and medium-and-micro-fertilizer treatments, and studied the effects of medium and trace fertilizers on the growth and yield of soybean influences. The results showed that application of medium and micro-fertilizer could increase plant height, dry matter accumulation and chlorophyll content (SPAD) of soybean at different growth stages. Compared with non-fertilization and conventional fertilization, the application of micro-fertilizer soybean yield was 14.5% and 4.7%. Differences reached significant and highly significant levels. Therefore, the application of trace elements and fertilizers on the production of soybeans played a positive role in promoting.
