衡136是河北省农林科学院旱作农业研究所培育的抗旱节水冬小麦新品种。在当前河北省地下水超采严重的背景下,为缓解农业用水矛盾突出问题,以2008~2011年国家黄淮冬麦区旱肥组、河北省黑龙港流域节水组的区域试验和生产试验结果,以及2011~2013年度国家小麦产业技术体系河北麦区节水高效品种筛选试验结果 (衡水)为素材,对衡136的产量、产量构成因素、产量稳定性、抗旱性、水分利用率和抗寒性进行了分析与评价,旨在推广抗旱节水型小麦品种,服务于农业生产。结果表明:在干旱胁迫或限水灌溉条件下,衡136一般产量为6000~7500kg/hm2,春浇1水时最高产量可达到9 000 kg/hm2以上。该品种具有节水抗旱、抗寒、丰产稳产性好、产量三因素协调、适应性广等优点,抗旱指数为1.130,水分利用率在0水、1水和2水灌溉条件下分别较对照品种石4185提高17.3%、14.9%和10.5%,节水性强。
Heng 136 is a drought-tolerant and water-saving winter wheat cultivar cultivated by Institute of Dry Farming, Hebei Academy of Agriculture and Forestry. Under the current serious groundwater over-exploitation in Hebei Province, in order to alleviate the prominent contradiction of agricultural water use, the regional trial and production test results of the national Huanghuai winter wheat-zone dry fertilizer group, Hebei Heilongjiang River Basin water-saving group from 2008 to 2011, and 2011-2013 National Wheat Industry Technology System Hebei Province Water-saving and Efficient Variety Screening Test Result (Hengshui) As material, the yield, yield components, yield stability, drought resistance, water use efficiency and cold resistance of Heng 136 Analysis and evaluation, aimed at promoting drought-resistant and water-saving wheat varieties, serving agricultural production. The results showed that the average yield of Heng 136 was 6000 ~ 7500 kg / hm2 under drought stress or limited water irrigation, and the highest yield could reach more than 9 000 kg / hm2 when spring was added. The variety has the advantages of water saving and drought resistance, cold resistance, high and stable yield, good coordination of three factors of yield, wide adaptability and the drought resistance index of 1.130. The water use efficiency of the varieties is respectively lower than that of the control varieties under 0 water, 1 water and 2 water irrigation conditions Stone 4185 increased by 17.3%, 14.9% and 10.5%, water-saving and strong.
