摘要:  为探明外源钙对盐碱地花生荚果发育的影响作用,以花育25号品种为试材,采用盆栽法,于盐碱土设置CaO用量分别为0 kg/hm2(Dck)、52.2 kg/hm2(DCa1)、104.55 kg/hm2(DCa2)、156.6 kg/hm2(DCa3)四个水平,并以非盐碱土空白为对照(Lck),研究了施用外源钙肥对盐碱土花生荚果发育动态、籽仁品质及产量的影响。结果表明:盐碱土对花生荚果生长具有抑制作用,DCa1、DCa2、DCa3处理均可促进盐碱土花生荚果与籽仁的生长发育,使籽仁生长时间提前,其中以DCa3处理提高荚果干重、体积和籽仁干重的幅度最大,分别提高24.1%、15.5%和20.36%。施用外源钙降低了盐碱土花生籽仁蛋白质与亚油酸含量,提高了籽仁可溶性糖、脂肪、油酸含量与油酸亚油酸(O/L)比值。此外,外源钙的施用提高盐碱土花生百果重、百仁重与出米率从而提高了产量,以DCa3处理(156.6 kg/hm2)提高产量的幅度最大,达到43%

Abstract:

In order to explore the effect of exogenous calcium on the development of peanut pods in the saline-alkali soil, Huayu 25 was selected as a test material and potted plant method was used to study the pod development, kernel quality and yield of peanuts in the saline-alkali soil after applying exogenous calcium fertilizer. In this experiment, four levels of CaO treatments in saline-alkali soil have been used, which were 0 kg/hm2 (Dck), 52.2 kg/hm2 (DCa1), 104.55 kg/hm2 (DCa2), 156.6 kg/hm2 (DCa3), and a normal soil treatment (Lck) was also included. The results showed that saline-alkali soil could inhibit the growth of peanut pods, and the application of exogenous calcium could promote the growth and development of peanut pods and kernels in saline-alkali soil and advance the development time of kernels. DCa3 treatment was the best way to increase the dry weight and volume of pods by 24.1% and 15.5%, and the dry weight of kernels by 20.36%. The content of protein and linoleic acid in peanut kernel in saline-alkali soil were decreased by applying exogenous calcium; and the ratio of soluble sugar, fat and oleic acid to oleic acid (O/L) in peanut kernel was increased. The application of exogenous calcium increased the weight of a hundred peanuts, the weight of hundred groundnut kernels, and the ratio of peanuts to kernels in the saline-alkali soil, and the effect of 43% increase was the best when the dosage of DCa3 was 156.6 kg/hm2.
