【摘要】 以‘沾化冬枣1号’和‘沾化冬枣2号’为试材,利用磁化处理的淡水和地下浅表层微咸水灌溉,通过对枣吊、叶片及果实的生长和养分含量测定分析,探究磁化水灌溉对枣生长及品质的影响。结果表明:(1)磁化水灌溉处理能显著提高叶片叶绿素含量和鲜质量,果实有机酸、维生素C、花青素含量,并且大幅度提高果实的耐贮性。(2)沾化冬枣1号经磁化(进口磁化器A400p)淡水灌溉处理,相比淡水对照枣吊长度与直径提高了11.375%和15.810%,单叶面积提高了12.418%,单果质量、含水量、果实横径和纵径分别提高了23.779%、2.377%、3.650%和5.071%;沾化冬枣2号经磁化(进口磁化器A400p)淡水灌溉处理,枣吊长度与直径提高了23.602%和13.710%,单叶面积与叶片厚度提高了23.622%和13.825%,单果质量和还原糖含量提高了12.526%和12.110%。(3)利用磁化(自主研发磁化器DS-948-1)地下浅表层微咸水灌溉处理沾化冬枣2号,与微咸水对照相比,果实含水量和还原糖含量分别提高了4.386%和9.158%。(4)灌溉水经磁化处理后,冬枣叶片矿质元素N、P、Cu含量提高(P<0.05)。磁化水灌溉处理有效促进了沾化冬枣的枝叶和果实生长发育,提高了果实的品质和耐贮性。更多还原

【Abstract】 Ziziphus jujuba‘Zhandong 1’and‘Zhandong 2’were chosen as the experimental material.The experimental materials were separately irrigated with magnetized fresh water and underground shallow saline water to test the influence of magnetized fresh water on the growth of bearing shoot,the growth and nutrient content of leaves and fruits.The results showed that:(1)Magnetized water irrigation treatment could improve the fresh weight of leaf,leaf area,chlorophyll content,organic acid,vitamin C and anthocyanin content significantly,and prolong the fruits storage period.(2)In the trial plot of Z.jujuba‘Zhandong 1’,treatment with magnetized(A400p) fresh water irrigation could increase the length and diameter of bearing shoot by 11.375% and 15.810%,single leaf area by 12.418%,single fruit weight by 23.779%,water content by 2.377%,fruit transverse diameter and longitudinal diameter by 3.650% and 5.071%.It had a significant difference(P < 0.05)compared with the un-magnetized fresh water irrigation treatment.In the trial plot of Z.jujuba‘Zhandong 2’,treatment with fresh water magnetized by imported magnetizer(A400p)could increase the length and diameter of bearing shoot by 23.602% and 13.710%,single leaf area by 23.622%,thickness by 13.825%,single fruit weight by 12.526% and fruits reducing sugar by 12.110%.It also had a significant difference(P < 0.05)compared with the un-magnetized fresh water irrigation treatment.(3)Treatment with magnetized(DS-948-1)underground shallow saline water irrigation could increase fruits water content by 4.386% and reducing sugar content by 9.158%.It also had a significant difference( P < 0.05) compared with the un-magnetized shallow saline water irrigation treatment.(4)The irrigation water treatment with magnetized could increase the leaf mineral nutrient content of N,P and Cu significantly(P < 0.05).Irrigating with magnetized fresh water had good function to the growth and development of branch leaves and fruits,and improved the quality and storage of fruits.更多还原
