摘要
根据在黑龙江省３１个县、市进行的多年谷子农业生态联合试验，并运用双重组合试验设计原理进行模型挂接，建立了黑龙江省谷子区域性农业生产数学模型。初步揭示了积温降水，土壤肥力及农家肥、化肥对谷子产量的影响程度及相互间的变化规律，并应用模型对谷子产量形成过程进行了模拟和预测。
Based on the joint experiments of millet agricultural ecology in cities and counties in Heilongjiang province and on the model commection according to the theory of double combination design, a mathematical model of millet regional production in Heilongjiang is established It reveals what extent the accumulated temperature, precipitation, soil fertility, farm manure, and chemical fertilizers can affect millet yield The model also shows the regularity of variation of those factors The model has already been applied to simulate the process of millet production and to predict the millet yield
