摘要
以小麦生物学特性和土壤植物营养学为依据,在小麦生育模拟基础上,建立了小麦生育优化动态模式和最佳经济效益施肥模型。输入简单易测的生物、土壤、气象因子,可以模拟出小麦生育的最佳叶面积动态、最佳茎蘖动态和最佳经济效益施肥量。并结合小麦实际资料,提出获取高产的措施与对策。为大田生产管理提供了可靠的理论依据。
Based on simulation of wheat growth phase, a computer simulation model for wheat growth optimization and fertilizer application with optimum economic performance was set up. After input simple factors of biology, soil and meteorology, the optimum leaf area, stem and tiller, ammount of economical manure can be simulated, and measurements for high yield were proposed.
