摘要
通过田间试验和室内分析相结合的方法,研究了皖中岗地花生配合施用B、Cu、Mo、Zn等不同微量元素肥料的效果及其对花生生长发育与产量形成的影响。结果表明,在N、P、K大量元素一定的供给水平上,合理配施B、Cu、Mo、Zn等,对花生的生长发育和产量形成均有显著效果。四种微量元素与N、P、K配施均能促进花生生长,有利于植株干物质积累,增加根瘤数和结果数,提高花生产量和经济效益。其中以配施硼肥和钼肥或者配施铜肥的增产增收效果最为显著。推荐N150、P90、K120、B9、Cu15、Mo30作为花生高产平衡施肥的配方。
The effect of cooperation fertilizing B, Cu, Mo and Zn microelements were studied and on growth and yield on peanut in Anhui hilly regions. The results showed that when N, P, K were applied at appropriate levels, rational cooperation fertilizing B, Cu, Mo, Zn significantly enhanced peanut growth, development, and realization of production. All of the microelements used in combination with N, P, K accelerated peanut growth, favored dry matter accumulation, increased the number of root nodules and pods per plant, and resulted in high yield and economic benefit, with B and Mo fertilizers on producing the best results and Cu fertilizers ranking second. To achieve high peanut yield, the formulation of N150,P90,K120,B9,Cu15,Mo30was thus recommended for balance fertilization in peanut production.
