RSPM-1是一个用于连作早稻纹枯病预测和药剂控病管理的系统动态模型。该模型由早稻生长、病情进展预测、作物受害损失估计和用药管理决策四个子模型组成。组装成的程序系统,以早稻栽插期、氮肥用量、气象条件、起始病情等为驱动变量,在微机上运转后,打印出各期病情、稻谷减收率、应采取的防治决策和所得纯收益。 RSPM-1 is a systematic dynamic model for continuous cropping rice sheath blight prediction and drug control management. The model consists of four sub-models of early rice growth, disease progression prediction, crop damage estimation and medication management decision-making. Assembled into the program system to early rice planting period, the amount of nitrogen, meteorological conditions, the initial condition as the driving variables in the computer running, print out the disease, the reduction rate of rice, prevention and treatment decisions should be taken and income Net income.
