温度高低,是影响农业丰欠的主要气象因素,对于水稻生产的影响更为显著。水稻生产上的低温冷害问题,近几年来,已引起人们的注意,有关单位相继开展了研究工作,并取得了成果。这方面的研究正在深入发展。为了促进防御冷害研究和为生产提供建议,根据过去所做的调查以及有关气象资料和水稻生产的历史资料,对辽宁省水稻生产发生低温冷害的规律性,冷害年减产的原因和防御措施等问题,加以分析和讨论。
The temperature is the main meteorological factor that affects the agricultural deficit, and the impact on rice production is more significant. In recent years, the issue of low temperature chilling injury in rice production has drawn people’s attention. The relevant units successively conducted research and achieved results. Research in this area is in-depth development. In order to promote the research on the prevention of chilling injury and provide recommendations for production, based on the surveys conducted in the past and the historical data on meteorological data and rice production, the regularity of low temperature chilling injury on rice production in Liaoning Province, the reasons for the reduction in chilling injury year and the countermeasures , To be analyzed and discussed.
