增施中微量元素肥料对大豆生长发育及产量的影响

Effect of Increasing Application of Secondary and Micro-element Fertilizers on Soybean's Growth and Yield

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。

For the purpose of superiority of secondary and micro-element fertilizers. Under field conditions, with ＇Hefeng No.55＇ （Glycine max） soybeans as materials and set no fertilization, conventional fertilization, micronutrient fertilizer treatments, researched on secondary and micro-element fertilizers on soybean growth and yield influence. The results showed that the secondary and micro-element fertilizers application can improve the different development stages of the soybean plant height, dry matter accumulation and chlorophyll content （SPAD）. Compared with no fertilizer and conventional fertilization, secondary and micro-element fertilizers increase yield by 14.5% and by 4.7%. Their difference was up to significant level and very significant level. Therefore, secondary and micro-element fertilizers application on soybean production played a positive role in promoting.
