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。民勤小枣和临泽小枣对离子毒害的表现较渗透胁迫明显
Two-year-old Minqin jujube and Linze jujube seedlings were planted in open-air pots. One year old branches were hydroponically cultured to study its salt tolerance. Salt stress symptoms of Minqin jujube and Linze jujube are leaf tarnishing → punctate chlorosis → water stains → wilting → drying or shedding under chloride-sulfate mixed salt stress. Hydroponics branches in salt solution ≤ 9.55dS / m (about 3.18%) less salt damage. When soil salinity was (14.55 ± 1.01) dS / m (about 4.63%) and (16.33 ± 1.55) dS / m (about 5.2%), the symptoms of salt damage were more serious in Linze jujube and Minqin jujube. Minqin jujube and Linze jujube poisoning performance than the osmotic stress significantly
