一、产量效应及生理功能 据已发表的资料,来自亚洲、非洲、南北美洲的所有试验报告,几乎无一例外地证明施钙对提高花生产量和改善花生品质有其重要意义。美国七个花生主产州以石膏为钙源进行施肥所得的结果也全部为正反应。未收录到欧洲国家关于花生施用钙肥增产效益的试验报告。花生施用钙肥的增产幅度虽然地区间、年度间的结果很不一致,但多数肥料配合的复因子试验有规 I. Yield Effects and Physiological Functions According to the published data, all the test reports from Asia, Africa, North and South America have almost no exception to prove that applying calcium is of great significance to improve the yield of peanut and to improve the quality of peanuts. The results of all seven peanut-producing states in the United States using gypsum as a calcium source were also positive. Not included in the European countries on peanut application of calcium fertilizer yield test report. Peanut application of calcium fertilizer yield increase Although the inter-regional and annual results are very inconsistent, but most of the fertilizers with complex factor test regulation
