小麦晚霜冻害形成机制与预警防御系统研究

Formation Mechanism of Wheat Late-frost Damage and Early-warning and Resistance System

依据建国后河南省历次小麦晚霜冻害成因机制,构建了小麦晚霜冻害预警防御系统,提出预防小麦晚霜冻害,可采取镇压法、连片覆盖或熏烟法、及时浇水、割棵、喷施叶面肥及选用抗冻品种等措施,为小麦安全生产、防灾减灾提供了理论依据。

Based on the formation mechanism of wheat late-frost damages in Henan Province since the foundation of the People＇s Republic of China, early warning and resistance system for the wheat late-frost damage was established. The control measures include large-scale coverage, fumigation, timely irrigation, plant-cutting, spraying leaf fertilizer, and application of frost-resisting varieties to provide theoretic basis for the safe pro- duction of wheat, control and reduce damages.
