摘要
本文由田间试验资料得知,棉花主茎出叶速率不仅与温度有关,而且与所处不同生育阶段有关。在此基础上,建立了适于计算机应用的棉花叶龄动态模拟模型,经检验具有较高的精度。根据叶龄模型可推算出植株的总叶片数、果枝数、果节数等器官,从而实现对植株的调控。
According to the data of field experiment, it was found that the rate of leaf emergencein cotton main stem was not only correlated to temperature, but also to developmentstage. A dynamic simulation model of cotton leaf age adapting in computer applica-tion lyas built. It can be used to simulate dynamic changing of leaf age with a higherprecision, if daily average temperature and parameters were input, using the leaf agemodel, cotton organs such as total leaf number, fruit branch number, nod numberand so on could be predicated,in this way adjusting and controlling of plant develop-ment could be done.
