【摘要】 以水稻的生物学特性为依据，利用田间试验实测资料，经过统计分析，确立了水稻总叶龄与环境变量之间的相关关系，建立了不同品种水稻的总叶龄模拟模式，发现日长是影响水稻总叶龄的主要因素，其次是温度。更多还原

【Abstract】 A leaf age model of rice is statistically established in context of field experimental data according to its biological properties and environmental responses. Results show that day length is the first factor affecting the leaf age and temperature the second.更多还原
