摘　　要：为探究不同山梨醇螯合钙喷施浓度对花生生长及养分吸收的影响,采用大田试验,以花育22号为试材,在施基肥基础上设置5个钙素喷施浓度处理(以Ca^(2+)计,单位g/L):0 (CK)、1.4 (T1)、1.6 (T2)、1.8 (T3)与2.0 (T4),测定了各处理对花生光合作用、收获期产量、品质、各器官干物质积累量及钾、钙、镁含量的影响。结果表明:(1)与CK处理相比,喷施山梨醇螯合钙提高了叶片SPAD值,促进了花生光合作用,尤其在结荚期;(2)喷施山梨醇螯合钙能提高花生产量及粗脂肪、粗蛋白含量,其中T2处理较CK处理分别提高11.48%、5.74%、7.82%;(3)喷施山梨醇螯合钙能够显著增加籽仁干物质积累量,有效提高花生生殖器官干物质占比,降低营养器官干物质分配比例,以T3处理改善效果较为突出,其次是T2处理;(4)喷施山梨醇螯合钙对花生各器官钾、钙、镁含量的影响不同,但总体上促进了花生对养分的吸收。主成分分析结果表明,喷施山梨醇螯合钙显著影响了花生生长发育。综合来看,喷施Ca^(2+)浓度为1.6~1.8 g/L的山梨醇螯合钙对花生增产提质效果更为突出。In order to explore the effects of different concentration of spraying sorbitol chelated calcium (Ca^(2+)) on the growth and nutrient absorption of peanuts,a field experiment was conducted with Huayu 22 as experimental material.Based on the application of base fertilizer,five Ca^(2+)spray concentrations were set up:0 g/L (CK),1.4 g/L (T1),1.6 g/L (T2),1.8 g/L (T3) and2.0 g/L (T4),and their effects on photosynthesis,yield and quality of peanuts,dry matter accumulation,the contents of potassium(K),calcium (Ca) and magnesium (Mg) in various organs of peanuts were determined.The results show that:1) Compared with CK,spraying sorbitol-chelated calcium can increase leaf SPAD value and promote peanut photosynthesis,especially in the pod setting stage;2) Spraying sorbitol-chelated calcium can improve the yield,crude fat and crude protein contents,which are increased by 11.48%,5.74%and 7.82%respectively under T2 compared with CK;3) Spraying sorbitol-chelated calcium can significantly increase dry matter accumulation in kernels,effectively increase the dry matter ratio in peanut reproductive organs,and reduce the dry matter distribution in vegetative organs.The improvement effects of T3 are more prominent,followed by T2.4) The effects of spraying sorbitol-chelated calcium on the contents of K,Ca and Mg are different in various organs of peanuts,but it generally promotes the absorption of nutrients in peanuts.The results of the principal component analysis show that the application of sorbitol-chelated calcium can significantly affect peanut growth under basic fertilization conditions.Generally speaking,the effect of spraying sorbitol-chelated calcium with Ca^(2+)concentration of 1.6 to 1.8 g/L is more prominent in the yield and quality of peanuts.
