小麦生长模拟模型的研究进展

Advance of Research on Wheat Growth Simulation Model

小麦生长模拟包括阶段发育、形态发生、光合与呼吸作用、干物质积累与分配、小麦与水分的关系、小麦的养分效应、小麦气象环境的模拟等几部分内容。综述了当前小麦的生长模拟模型研究状况,其中小麦光合产物分配模拟模型仍基本处于经验性模型,有待进一步研究发展为机理性模型,以提高其解释性水平。这将会促进农田水肥一体化管理技术和农田作物群体动态调控技术的发展,为农田精准灌溉和精准施肥的实践提供理论依据。

The wheat growth simulation include seven aspects, such as growth period, morphological development, photosynthesis and respiration, the partition and accumulation of dry matter, the relation between wheat and water , the nutrient effect of wheat, the meteorological environment of wheat. The research on wheat growth simulation model is reviewed in this paper. The simulation model for wheat photosynthetic products distribution is still basically at the empirical model and should be further researched and developed to he a rational model to raise their explanation level. This will promote the development of the water-fertilizer integrated management technology and crops group dynamic controlled technology and will provide theoretical base for the practice of farmland precision irrigation and fertilization.
