据1979年统计资料,我国盐碱地小麦面积达3800万亩,仅鲁西北四区盐碱地小麦面积就达800万亩左右。在这些地区中,由于盐害严重,小麦产量低下。要提高盐碱地区的小麦产量主要有两条途径:一是改良盐碱土,二是选用耐盐的作物品种。实践证明,选用耐盐的作物品种是最经济有效的方法。但有关小麦耐盐育种的报道很少。山东省德州地区农业科学研
According to statistics in 1979, the area of wheat in our country’s saline-alkali land reached 38 million mu, only about 8 million mu of wheat in saline-alkali land in the four northern areas of Shandong Province. In these areas, wheat production is low due to severe salt damage. To improve the yield of wheat in saline-alkali areas there are two main ways: First, to improve saline-alkali soil, the second is the selection of salt-tolerant crop varieties. Practice has proved that the selection of salt-tolerant crop varieties is the most cost-effective method. However, few reports on wheat salt-tolerant breeding.
