摘要
综述了花生的缺钙症状,钙素对花生生长发育、产量组成、品质的影响及其形态解剖、生理生化及分子生物学的机理,归纳了钙肥与其他肥料配施的综合效应,对比分析了花生缺钙的几种判断标准。认为今后花生钙素营养研究似应进一步研究缺钙导致花生空壳的内部机理;改进花生缺钙的诊断方法与判别标准;广泛收集鉴定耐低钙或钙素利用率高的花生种质,并进行有关的品种改良;加强钙肥的精量、快速、高效、缓释等施用技术的研究。
This paper reviewed the symptoms of calcium deficiency, the effects of calcium nutrition on the growth and development, yield components, quality, morphological and anatomical structure and the mechanism of biochemistry and molecular biology of peanut crop. The combined effects of applying calcium and other fertilizers were summarized and several judging criteria of calcium deficiency of peanut were compared. The future research areas of calcium nutrition should focus on the followings： further demonstrated the internal mechanism of calcium deficiency that resulted in unfilled peanuts; improved diagnostic methods and judgment criteria of calcium deficiency; widely collected and screened peanut germplasm with tolerance to low calcium or high utilization of calcium and improved related cuhivars; enhanced the precise, fast, efficient,sustained-releasing applying technology of calcium fertilizers.
