摘　　要：为探明覆盖醋渣对海滨滩涂新开垦盐渍土麦田小麦生长的影响,在盐渍土麦田小麦播种以后撒施覆盖45 t/hm^(2)醋渣,分析了覆盖醋渣处理对小麦拔节期叶片叶绿素相对含量、株高和地上部干重的影响。结果表明,与未覆盖醋渣的对照相比,覆盖醋渣处理的拔节期叶片叶绿素相对含量、株高和地上部干重等均显著提高。因此,播种后麦田覆盖醋渣可促进盐渍土麦田小麦拔节期的生长发育。In order to find the effects of vinegar residue mulching on the growth of wheat in the newly reclaimed saline soil fields of coastal beach,vinegar residue(45 t/hm^(2))was used to cover wheat fields after wheat sowing.The effects of vinegar residue mulching on the relative content of chlorophyll(SPAD)of wheat leaves,plant height and aboveground dry weight at jointing stage were analyzed.Results showed that the relative content of chlorophyll(SPAD)of wheat leaves,plant height and aboveground dry weight mulched with vinegar residue were significantly higher than those of the control.Therefore,vinegar residue mulching in wheat field after sowing could promote the growth and development of wheat at jointing stage in saline soil.
