硅、钙对花生新品种郑农花9号的生育及产量的影响

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

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。

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%.Calcium peanut yield components for the greatest impact,first on the longest average length of lateral branches,full fruit number per plant on average 11.15,the average berry weight 273.25 g,one hundred kernel weight 117.25 g.Rice yield and plant full the number were highest,and the average yield calcium was 5 386.01 kg.The three treatment increased significantly.The average yield of silicon calcium and magnesium fertilizer was 5 260.95 kg.The two treatment increased significantly.The average yield 5 190.08 kg efficient silicon fertilizer.A combination of calcium influenced significantly higher and more reliable than calcium-free fertilizers on the yield and composition of fertilizers.
