摘要
选用2年生民勤小枣和临泽小枣幼苗露天盆栽,并对1年生枝进行水培,研究其耐盐性。在氯化物-硫酸盐型混合盐的胁迫下,民勤小枣和临泽小枣的盐害症状为叶失去光泽→出现点状失绿→变成水渍状斑点→萎蔫→干枯或脱落。水培枝在≤9.55dS/m(约3.18%)的盐溶液中盐害较轻。土壤含盐量为(14.55±1.01)dS/m(约4.63%)和(16.33±1.55)dS/m(约5.2%)时,临泽小枣和民勤小枣出现较重的盐害症状。
The saline resistance to chloride sulphate salts of young tree of Minqin jujube and Linze jujube is identified by an experiment that young tree were planted in bins and hydropnic twig in saline solution in open. The response on saline injure is leaves losing sheen→appearing light green dot→changing into water stains→wilting→dry or go down.The hydroponic twigs of jujube are severely injured in≥9 55 dS/m salt solution. When salt consists is more (14.55±1.01) dS/m (about 4.63%) and (16.33±1.55) dS/m (about 5.22%),the young tree of Minqin jujube and Linze jujube is severely injured by salt.
