石膏作为花生钙源的价值曾有过多次报导。在低含钙量的土壤上(每公顷80—200公斤)施用石膏有着最大的产量反应。曾有过报导,施用石膏提高了花生种子品质,花生种子内氮和油份含量变化很小。一些研究者试图用钙处理改善种子含油率,但变化很小。结果他们指出钙肥影响油份含量主要通过改善种子品质。曾有报导施钙后花生种子内含氮量降低或者无变
The value of gypsum as a calcium source for peanuts has been reported many times. Application of gypsum in low-calcium soils (80-200 kg ha -1) has the greatest yield response. It has been reported that the application of gypsum improves the quality of peanut seeds with little change in the content of nitrogen and oil in the peanut seeds. Some researchers tried to use calcium treatment to improve seed oil content, but little change. As a result, they pointed out that the effect of calcium fertilizer on oil content is mainly through improved seed quality. It has been reported that the amount of nitrogen in peanut seeds after application of calcium is reduced or unchanged
