银川灌区盐化土面积较大,据1962年调查统计,约占总耕地面积的67%。盐化度变幅约为0.1～1.0%,盐分组成以氯化物——硫酸盐为主。春麦耐盐性较弱,目前只在非盐化土与轻盐化土上种植,面积仅100万亩左右;同时单位面积产量的提高也受到一定限制。因此,研究鉴定春麦品种的耐盐性,以便配合盐化土改良措施,因地制宜地选用耐盐性强弱不同的优良品种,对发展本区春
Yinchuan irrigation area larger saline soil, according to 1962 survey statistics, accounting for about 67% of the total arable land. Degree of salinity change of about 0.1 to 1.0%, salt composition of chloride - sulfate-based. Spring wheat salt tolerance is weak, currently only non-saline soil and light saline soil planted, an area of only about 1000000 acres; the same time, the yield per unit area is also subject to certain restrictions. Therefore, the study identified the salt tolerance of spring wheat varieties in order to cooperate with the saline soil improvement measures, according to local conditions, the use of different varieties of salt resistance of different strengths and weaknesses in the development of spring
