硅、钙对花生新品种郑农花9号的生育及产量的影响

以花生品种郑农花9号为材料进行硅、钙基肥试验,基施硅钙镁肥、高效硅肥、钙肥,探讨硅、钙元素对花生生长及产量的影响。结果表明:3种肥料均可使花生茎秆粗壮、生长旺盛、抗逆性增强,病害发生率降低;硅钙镁肥使花生出苗期提前2 d,出苗率、单株结果数优于钙肥和高效硅肥。所有处理荚果产量增产41.7～717.0kg/hm2,增产幅度0.85%～14.7%。钙肥对花生产量构成因素的影响最大,第一对侧枝的平均长度最长,单株饱果数平均11.15个,平均百果重273.25 g、百仁重117.25 g,出米率和单株饱果数都是最高,钙肥的平均单产为5 386.01 kg,其3个处理增产极显著,硅钙镁肥的平均单产为5 260.95 kg,其两个处理增产极显著,高效硅肥的平均单产为5 190.08 kg。含钙的肥料组合较之无钙的肥料对产量及其构成因素的影响显著,更为可靠。

Effects of silicon, calcium on growth and yield of the peanut variety Zhengnonghua 9

Study on silicon,calcium and magnesium fertilizers for growth and yield of peanut variety Zhengnonghua 9 showed that three fertilizer could make the peanut stem stout,vigorous growth,resistance enhanced,the incidence of disease reduce;Silicon calcium and magnesium fertilizer resorted to early seedling stage 2 day,germination rate,the number of results was superior to calcium fertilizers and plant efficiency silicon.All processing pod yield increased 41.7~717.0 kg / hm2.The yield increased 0.85%~14.7%.Calciu...
