摘  要:
大豆花叶病毒(SMV)流行和防治的模拟系统SIMSMV是由大豆生长、病害日侵染率、显症率、种子传毒率、种子褐斑率、产量损失6个子模型和播种种子带毒率允许水平及介体蚜虫防治模型所构成。本模型只需输入几个简单的初始变量即可实现对SMV流行、危害的模拟及制定病害防治决策。经过三年的检验和试用,证明本模型系统结构合理、模拟准确、决策可靠。

摘  要:
SIMSMV was constructed with 6 submodels for SMV epidemics and losses, and with 2 management decision models. The submodels consist of (1) GROWTH, to describe soybean developmental stages, (2) INFECTION, to calculate daily infection rate,(3) INCUBATION, for rate of systemic symptom appearance, (4) SEED TRANSMISSION,for seed transmission rate, (5) SEED-COAT MOTTLING, to indicate percentages of seed-coat mottling, (6) YIELD LOSS, to compute the percentage of yield loss. The management decision systems include (1) the decision making for sowing seeds to permit levels of seed-born rate to control SMV epidemics, (2) the decision making to control vector aphids with chemicals and to time their spraying dates.SIMSMV was validated and tested with various simulation experiments includ. ing epidemiology, damages and making decisions for three years respectively. The results are considered rational, accurate and practical.
