摘要:

以花生品种606为试材,在旱棚池栽人工控水条件下,研究了钙肥不同用量对花针期和结荚期干旱胁迫下花生的营养生长、生理特性、产量及品质的影响.结果表明:干旱胁迫下施钙,可以促进花生的营养生长,提高叶片的叶绿素含量、净光合速率和根系活力,提高干旱后复水过程中花生的恢复能力,缓解干旱对花生的不利影响;增加了花生荚果和籽仁的产量,尤其是增加了单株结果数和出仁率.施钙提高了籽仁中的脂肪和蛋白质含量,改善了干旱胁迫下花生的籽仁品质.在本试验条件下,施钙量为300 kg·hm-2时效果最佳.
 

Abstract:

An experiment was carried out to study the effects of different rates of calcium application on peanut growth, physiological characteristics, yield and quality under drought stress at pegging stage and pod setting stage in pool cultivation with rainproof, using variety 606 as experimental material. The results showed that applying Ca fertilizer under drought stress could promote peanut growth, increase the chlorophyll content, leaf photosynthetic rate and the root vitality, increase the recovery ability of peanut during rewatering after drought stress, alleviate the impact of drought stress on peanut. Applying Ca fertilizer under drought stress increased pod and kernel yields because of the increase of kernel rate and pod number per plant. It also increased the fat and protein contents of peanut kernel, and improved peanut kernel quality under drought stress. It was suggested that 300 kg·hm-2 Ca application is the best choice to alleviate the impact of drought stress on peanut.
