- 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.
