摘要
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 the peach strain‘3-18＇from Peach Resources Nursery and Laboratory of Henan Agricultural University as material,by spraying CaCl2,which in different concentrations and different times on its foliar.The physiological index was determined,in order to seek the rational applying concentration of Ca2＋and provide theoretical basis for scientific experiment in the future.The results showed that the chlorophyll content was improved.The MDA content was affected significantly.However,the effect on the dry weight and fresh weight wasn＇t obvious.
