摘要: 为解决生产中蓝莓的缺铁黄化问题,通过叶面施用硫酸亚铁、柠檬酸与硫酸亚铁混合液、螯合铁(EDTA-Fe)和土壤施用硫酸亚铁处理对两个蓝莓品种(‘蓝丰’‘蓝金’)叶片的叶绿素a、叶绿素b、类胡萝卜素以及叶绿素/类胡萝卜素含量的变化,进行施肥前后比较。结果表明,各处理中,叶绿素b、类胡萝卜素及叶绿素/类胡萝卜素的增长量均表现为叶面施用EDTA-Fe或叶面施用柠檬酸与硫酸亚铁混合液>叶面施用硫酸亚铁>土壤施用硫酸亚铁>CK。叶绿素a无明显规律。施用铁肥对提高蓝莓叶片叶绿素b含量效果最好。叶面施肥效果比土壤施肥效果好,且叶面施用EDTA-Fe使蓝莓叶片内光合色素含量增加最显著。

Abstract: In order to solve the problem of Fe-deficient chlorosis of blueberry in production,the changes of chlorophyll a, chlorophyll b, carotenoid and ratio of chlorophyll to carotenoid of two blueberry varieties(‘Bluecrop’ and ‘Bluegold’)were obtainedafter fertilizing fertilizer, which included spraying on leaves with ferrous sulfate, citric acid and ferrous sulfate, iron chelate(EDTA-Fe)and fertilizing ferrous sulfate in soil. The resultsshowedthe effect of EDTA - Fe or mixture of citric acid and ferrous sulfate by spraying on the leaves>ferrous sulfate by spraying on the leaves>using ferrous sulfate in soil>CK, according to the chlorophyll b, carotene and ratio of chlorophyll and carotene in leaves. Apparent regular wasn’ t found in chlorophyll a. The increment of chlorophyll b in blueberry leaves was the bestby using iron fertilizer. The effect of spraying on leaves was better than fertilizing in soil. At the same time, the increment of photosynthetic pigment in blueberry leaves was the biggest by spraying EDTA-Fe on leaves.
