蔺草开花与温光条件关系的数学分析及模拟模型

本文对蔺草开花与温光条件关系作了分析研究.根据浙江宁波市郊区1992-2000年的农业气候资料的分析计算表明,影响蔺草冈山3号草茎开花率（SFR）的主要气象因子为12月下旬、2月中旬的平均气温,2月下旬的日照时数和3月下旬的雨量.依据春化作用的机理和上述影响因子的分析,得SFR的模拟模型为:SFR=其中∑j

Mathematical Analysis and Simulation Model of Relations of Mat Rush Flowering to Light and Temperature Conditions

The relations of flowering to light and temperature conditions in Mat Rush were studied based on agro-climatic data during 1992 to 2000. The results indicated that the main climatic factors which affect stem flowering rate (SFR) of Mat Rush (cv. Gangshan No.3) were the third ten-clay period average temperature (AT) in December and the second ten-day period in February, sunlight hours(SH) of the third ten-day period in February and the rainfall of the third ten-day period in March. According to vernalization mechanism and above analysis, the simulation model for SFR was: SFR = 1.023 + 0.258{} The estimatingresults approximated to the observed value of 1992/1993-1998/1999. and predicted SFR=5.73% in 1999/2000, which was 0.13% differentiation from the observed one (5.6%). The model better illustrate the relationship between flowering and light and temperature conditions. Interaction between vernalization and sunlight hours was indicated as well, especially in the late stage of vernalization.
