通过分期播种田间试验资料，建立水稻旱育抛秧生长发育的动态模拟模型，包括叶面积发展、光合作用、呼吸作用、干物质积累与分配等。重点探讨叶面积发展与温度的关系、光合作用简化算法、净光合量的求算、分配系数随发育期的变化等。对抛秧稻和手插稻作对比分析，在一定程度上阐述了抛秧稻的高产机制。各部分工作均紧扣气象因子的影响。 The dynamic simulation model of paddy seedling throwing and seedling growth and development was established by staging the field experiment data, including the development of leaf area, photosynthesis, respiration, accumulation and distribution of dry matter. Focus on the relationship between leaf area development and temperature, photosynthesis simplification algorithm, the calculation of net photosynthesis, partition coefficient with the development of changes. Throwing rice and hand inserted rice for comparative analysis, to a certain extent, elaborated the throwing rice high yield mechanism. All parts of the work closely linked to the impact of meteorological factors.
