小麦霜冻害模拟模型研究进展

Advance on Simulation Modeling of Frost and Freezy Injury in Wheat

随着科学技术的不断发展,作物模拟模型作为综合学科的代表已成为农业信息化的核心技术。小麦在粮食生产中的地位突出,国内外关于小麦模型的研究尤为深入,小麦生育期模拟、产量预测和评估等方面的作物模型已广泛应用于生产实践。相比之下,小麦灾害模拟模型的研究较少。我国小麦低温灾害模型的研究起步较晚,虽然近年来在该领域取得了长足进步,但与国外同类研究相比仍显不足。本文综述了我国小麦低温灾害模型的研究进展,对国外可应用于我国小麦低温灾害研究的模型进行适用性分析,并对模型构建中存在的问题、注意事项和发展前景进行了探讨。

With the accelerating development of science and technology,crop simulation models,representative of the synthetic subject,have become the core of agricultural information technology.As wheat plays an extremely important role in grain production,experts at home and abroad have conducted deep research into wheat models.Most of the models have been widely used for yield prediction,drought assessment and growth and development of wheat.Few studies,however,have been made in terms of disaster models.Research on modeling low temperature disaster in wheat started late in China.Although considerable progress has been made in this area in recent year with the help of previous technology base,it is still insufficient compared with similar studies abroad.In this paper,we reviewed the advances in models for low temperature disaster,analyzed the applicability of foreign crop models in China,and discussed the existing problems,considerations and prospect in developing models.
