氨基酸螯合钙铁镁与硼配施对花生生长和产量的影响

Effects of Combined Application of Amino Acid Chelated Calcium,Iron,Magnesium with Boron on Growth and Yield of Peanut

为考察氨基酸螯合钙铁镁配施硼砂对花生生长及产量的影响,在3个试验点开展了田间小区试验。结果表明:施用不同浓度的氨基酸螯合钙铁镁处理均可以增加花生分枝数,促进主根生长,提高花生产量;花生分枝数分别增加0.3~2.2、0.1~0.5、0.5~1.1根/株,产量分别提高17.5~75.0、26.7~62.3、4.5~35.6 kg/亩(1亩=667 m2),且添加1.0%氨基酸螯合钙铁镁配施硼砂的处理均表现为效果最好;施用氨基酸螯合钙铁镁处理主要通过增加单株结荚数来提高花生产量。

In order to investigate the effects of combined application of amino acid chelated calcium,iron and magnesium with borax on the growth and yield of peanut,a field plot experiment is carried out in three experimental points.The results show that the application different concentrations of amino acid chelated calcium,iron and magnesium can increase the number of peanut branches,promote the growth of the main root,and increase the peanut yield.The number of peanut branches increases by 0.3-2.2,0.1-0.5,0.5-1.1 root/plant,and the yield increases by 17.5-75.0,26.7-62.3,4.5-35.6 kg/mu(1 mu=667 m 2),and the treatment adding 1.0%amino acid chelated calcium,iron and magnesium combined with borax shows the best effect;the treatment of applying amino acid chelated calcium,iron and magnesium increases the peanut yield mainly by increasing the number of pods per plant.
