小麦的落粒性,往往给生产带来损失,致使易落粒的品种,在生产使用上受到限制。我省许多地区特别是中部及河西地区,因风雹灾危害的原因,抗落粒性也属鉴定小麦品种适应性的主要指标之一。 The falling of wheat often brings losses to the production, resulting in the easy-falling varieties, which are limited in production and use. In many areas in our province, especially in the central part and Hexi area, the anti-dropper property is also one of the main indexes to identify the adaptability of wheat varieties due to the hail damage caused by wind and hail.
