河北省东部低平原区旱碱麦品种综合评价

Comprehensive Evaluation of Drought Resistant and Salt Alkali Tolerant Wheat Varieties in the Eastern Low Plain Area of Hebei Province

随着新育成品种的不断推出,在河北省东部低平原区种植的小麦品种也随之增多。为了筛选适合该区域种植的抗旱、耐盐、丰产小麦品种,在盐分含量3.26 g/kg的盐碱地上,选用在一定范围内得到了推广应用的8个优质旱碱麦品种进行品种比较试验,通过比较小麦株高、穗长、小穗数、不孕小穗数、不孕小穗率、产量构成因子、产量和子粒蛋白质含量,对各品种进行综合评价。结果表明:捷麦19和小偃156产量较高、生态适应性强,为适合河北省东部低平原区种植的旱碱麦优选品种,其中捷麦19株高最大,小偃156蛋白质含量最高。在降水量多的地区或年份,可以追求旱碱麦的产量和品质,推荐种植小偃156;反之,则需要种植抗旱性强、产量稳定的捷麦19。

With the continuous introduction of newly bred varieties,the number of wheat varieties planted in the eastern low plains of Hebei Province has also increased.In order to select drought resistant,salt tolerant,and high-yield wheat varieties suitable for planting in this region,8 high-quality drought alkali wheat varieties that have been promoted and applied within a certain range were selected for variety comparison experiments on saline alkali soil with a salt content of 3.26 g/kg.By comparing the plant height,spike length,spikelet number,sterile spikelet number,sterile spikelet rate,yield composition factors,yield,and grain protein content,a comprehensive evaluation was conducted on each variety.The results showed that Jiemai 19 and Xiaoyan 156 had higher yields and strong ecological adaptability,which are the optimal varieties for planting dry alkali wheat in the low plain areas of eastern Hebei Province.Among them,Jiemai 19 had the highest plant height and Xiaoyan 156 had the highest protein content.In the areas or years with high precipitation,the yield and quality of dry alkali wheat can be needed,and it is recommended to plant Xiaoyan 156.On the contrary,it is necessary to plant Jiemai 19 with strong drought resistance and stable yield.
