水肥调控对水稻茎蘖动态影响模拟研究
Effects and dynamic model of rice tiller based on water and Fertilizer management
为了探讨水稻茎蘖生长动态及其消长规律对水肥因子的响应及其补偿效应,通过田间试验分析,并建立水稻茎蘖动力学模型进行模拟。结果表明:分蘖前期的适度单因子水、双因子水肥亏缺使得分蘖中后期控制灌溉水稻茎蘖增长高于常规灌溉,表现出明显的生长补偿效应;生育期中期适度水、肥亏缺能够维持较高的水稻茎蘖量;生育期后期单因子水亏缺、双因子水肥亏缺有利于提高水稻有效穗率,形成合理的高产群体。控制灌溉有着较常规灌溉更为合理的水稻茎蘖生长动态及其消长规律,呈前期增长快、中期控、后期高的动态变化过程,形成合理群体,为高产打下坚实的基础。
hrough analysis of the field test, and the dynamics simulation model of rice tiller, the article discuss the response between water and fertilizer and the dynamics growth of the rice growth and the compensation effect. in the early tillers, single factor water and more factors water and fertilizer deficit makes the rice tiller of the control irrigation grow faster than the conventional treatments in the later tiller, and shows that growth compensation effect; single water and fertilizer maintain a high number of rice tillers in the moderate growth; in the later Growth Period, single water and multi-factor of water and fertilizer deficit improves rice panicle rate to form a rational and high-yielding groups. The control irrigation have better rice tiller growth dynamics for the high yield than the conventional treatments.
