以河南农业大学桃资源圃的桃品系‘3-18’为试材,对其喷施不同浓度和次数的氯化钙,并测定叶片的生理指标,以探寻能够显著提高叶片生理指标的合理钙肥浓度,以期为优质桃生产提供参考依据。结果表明:喷施氯化钙可以提高其叶片的叶绿素含量,对叶片丙二醛(MDA)含量有显著影响,但不能显著提高其叶片干鲜重。
Taking peach cultivar ’3-18’ of peach garden of Henan Agricultural University as test material, different concentrations and times of calcium chloride were sprayed on it, and the physiological indexes of leaves were measured to find the reasonable calcium which can significantly improve the physiological index of leaves Fertilizer concentration, with a view to provide a reference for the quality of peach production. The results showed that spraying calcium chloride could increase the content of chlorophyll in leaves and significantly affect the content of malondialdehyde (MDA) in leaves, but could not significantly increase the dry weight of leaves.
