水稻生长发育和产量形成气象影响模拟模式

The Simulation Models of Weather Effect on Growth and Development and Yield Dynamics of Rice Community

根据田间分期播种试验资料,引入当量温度理论,研究水稻生长发育动态过程,建立了水稻叶龄生长、发育期进程、分蘖过程、灌浆过程、产量结构逐日气象影响模式和指标系统;建立了水稻进入低温敏感期逐日出穗数量分布概率模式、日内气温标准分布函数和时积温计算模式、日空壳率计算模式、水稻障碍型冷害平均空壳率模式。综合结构产量系数、障碍型冷害减产率、灌浆完成百分率,建立了水稻气象产量模式。

Based on field experiment of different seeding,introducing the theory of equivalent temperature,studying the progress of growth and development of rice,the simulation models of effect of weather on leaf age growth,phenology,tillering,fill seed,yield Structure forming and indexs were Established.Meanwhile,the models on heading progress statistical distribution in sensitive period under lower temperature,temperature standard distribution and cumulative temperature by hour in a day,unfruitful seed percentage of a day and average induced by low temperature disaster were Established;general considering factors of yield structure,low temperature disaster,final fill seed percentage,the models of effect of weather on yield of rice were Established.
