摘  要：
为了开发利用盐碱地,筛选适宜盐碱地区种植的小麦品种,以耐盐3号、8号小麦新品系为材料,以当地主栽品种宁春18号和764为对照,在甘肃白银引黄灌区不同程度盐碱地上进行了耐盐性试验研究。结果表明:耐盐3号、8号小麦在土壤全盐含量为0.299%～0.786%的盐碱地上种植,耐盐性强,比对照小麦增产明显。当土壤全盐含量0.299%时,小麦的农艺性状受到轻度影响,耐盐小麦比对照小麦略有增产;当土壤全盐含量在0.299%～0.786%时,小麦的生长发育受到明显的抑制,随着盐分浓度的上升,耐盐小麦比对照小麦增产幅度提高,优势明显;当土壤全盐含量在0.786%～0.828%时,小麦生长发育受到严重抑制,随着盐分浓度的继续上升,小麦产量急剧下降,耐盐小麦比对照小麦有优势,但产量太低,不宜种植。

摘  要：
In order to open up and utilize the saline-alkali lands and to select new salt resistant wheat varieties, two varieties Naiyan 3 and Naiyan 8 were planted on different saline-alkali lands in the irrigated areas along Yellow River in Baiyin city in Gansu province, Ninchun 18 and 764 as contrast varieties. The results showed that Naiyan 3 and Naiyan 8 had stronger salt resistance and higher yield than the contrast varieties when they were planted on saline-alkali lands with a salinity of 0.299%~0.786%. When the soil salinity was 0.299%, the agronomic characters of wheat were affected to a light degree, and the yield of salt-resistant varieties was slightly higher than that of the contrasts. When the soil salinity was between 0.299%~0.786%, the growth of wheat was restrained obviously. As the soil salinity increasing, the production increase rate of salt-resistant varieties was higher than that of the contrasts and their superiority was obvious. When the soil salinity was between 0.786%~0.828%, the growth of wheat was restrained seriously. As the soil salinity increasing, the yield of wheat dropped rapidly, and the salt-resistant varieties were superior to the contrasts. But their yield was very low so that they were not suitable for planting.
