摘要
在花生苗期、花针期和荚果期分别进行叶面施肥,结果发现在花针期喷施过磷酸钙和硼酸可以明显提高植株的光合指标,从而提高花生的光合效率。同时,对花针期花生体内的植物激素含量变化研究发现,在该时期叶面喷施过磷酸钙和硼酸可以在很大程度上提高植株的玉米素和生长素含量,从而促进该时期花生的生长发育。
Foliage spraying was used at seedling,blossom and pod stage of peanut respectively,the results showed that the photosynthetic indexes were obviously increased by spraying of calcium superphosphate and boric acid at blossom,which improved the photosynthetic efficiency and yield of peanut.At the same time,the change of content of plant hormones at blossom stage was studied,the results showed that the contents of Zeatin and IAA were evidently increased by spraying of calcium superphosphate and boric acid,which promoted the growth of peanut at blossom.
