盐土地区小麦品种利用问题探讨

STUDIES ON UTILIZATION OF WHEAT CULTIVARS IN SALINE-ALKALISOIL

１９８９～１９９３年度在山东滨州等盐碱度不同的盐土地上对１９个小麦材料的适应性和产量表现进行了试验研究。结果表明，在盐碱度相对稳定的盐碱地上，耐盐品种比普通品种平均增产１２．８％～４５．８％。这样的盐碱地以耐盐品种为主。在非盐碱地上，普通丰产品种比耐盐品种平均增产３４．１％，这种地不宜种植耐盐品种。在花碱地上，二系种比纯系品种平均增产９．１％，且比耐盐品种产量潜力大，花碱地应利用二系种稳定提高产量。

The experiments were conducted at Binzhou、Boxing and Zhanhua, Shandong Province during 1989￣ 1993. Included in the experiments were 3 salt-enduring,4 non-salt-enduring wheat cultivars, and 12 biblends formed from the three salt-enduring and four non-salt -enduring cultivars. The results showed that: 1) yielding ability of salt-enduring cultivars was higher than that of non-enduring ones, and the average yield incerased significantly by 12.8%￣ 45.8% on the soil with a stable saline-alkali content, so, this type of cultivars is suitable to grow in such soil. 2) the average yield of non-saltenduring cultivars was 34. 1% more than that of the salt-enduring ones, and had higher yielding ability in non-salt-soil, and it is not suitable to grow salt-enduring cultivars in shuch soil.3) the yield of biblends was higher than that of pureline cultivars including the salt-enduring cultivars, so it is better to use wheat biblends cultivars in piebald saline-alkali soil.
