小麦是我国三大粮食作物之一,在促进农业生产发展和保证粮食安全中发挥着重要作用。保持小麦持续高产稳产是我国粮食生产的重要工作。在诸多影响小麦产量的因素中,种子是最主要的因素。据有关部门统计,我国2014年农作物种子对农业增产的贡献率已经达到47%。但是,由于受多种因素的制约,在生产实际利用中,并没有真正的发挥小麦种子的综合增产能力。小麦产量的高低决定于种子内在种质优劣,种子的健壮程度,得当的耕作管理技术和有利的自然条 Wheat is one of the three major food crops in our country and plays an important role in promoting the development of agricultural production and ensuring food security. Maintaining the sustained high and stable yield of wheat is an important task for food production in our country. Among the many factors affecting wheat yield, seeds are the most important factor. According to statistics from relevant departments, the contribution rate of China’s crop seeds to agricultural production in 2014 has reached 47%. However, due to the constraints of many factors, the actual utilization of production has not really brought into full play the capacity of wheat seed. The level of wheat yield depends on the quality of the seed’s germplasm, the robustness of the seed, proper farming management techniques, and favorable natural conditions
