摘要
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。
In the content of multiple planting experimental data, a dynamic model for HSTP rice is developed, including leaf area development, photosynthesis,respiration, dry matter accumulation and allocation sub models. Much investigation is made on the relationship between I LA and temperature, simplified calculation for photosynthesis, estimation of net assimilation and variation of dry matter allocation coefficient with phenological stage.In comparison with traditional manual transplanting (MT) rice, the reason why HSTT rice could reach high yield is revealed in combination with meteorological influence.
