摘  要:
对因红壤土遭受碱害而导致缺铁失绿的芒果园进行土壤渗施土壤改良剂处理,研究各处理对植株根际土壤pH值、HCO3-浓度、有效铁含量以及叶片叶绿素、活性铁、总铁含量的影响。结果表明:经土壤改良剂处理,可明显降低碱害红壤土0~40cm土层,尤其是0~20cm土层的pH值和HCO3-浓度,大幅度提高0~20cm土层的有效铁含量,20~40cm土层也得到相应的提高;土壤渗施盐碱土壤改良剂4个月后,失绿芒果植株叶片叶绿素、活性铁和总铁含量都显著高于对照和处理前的含量水平,其中叶绿素含量的增加最显著,活性铁含量的增值比总铁的高。

摘  要:
A soil improver treatment to mango garden suffering from alkaline harm for research of different treatments' impacts on soil pH,HCO3 density,effective iron content,leaf chlorophyll content,leaf effective iron content and leaf total iron content.The results show that the improver can reduce obviously the pH and HCO3 density in soil layer of 0~40 cm,increase greatly the effective iron content of 0~20 cm soil layer.Four months after the application of improver, the leaf chlorophyll,effective iron,total iron contents of mango all are higher obviously than the control group and level before treatment,among them,the increase of chlorophyll is most obvious and the increase of effective iron content is higher than that of total iron content.
