贮藏玉米中霉菌菌相构成分析及其优势霉菌生长预测模型的构建

影响贮藏玉米品质的主要危害之一是霉变，其中优势霉菌起着决定性作用，其消长影响玉米品质和贮藏时间。现有贮藏方法存在着针对性差、能耗高、药剂残留等缺点。为此，本项目针对危害贮藏玉米品质的微生物因素，采用预测微生物学理论，开展玉米中有害霉菌的生长预测模型与模拟的研究，对实现“生态储粮”，确保玉米贮藏安全，具有重要的理论研究价值。 . 本项目的主要研究内容为：1）研究不同地域玉米中霉菌的多样性，分析贮藏玉米中的菌群构成。2）通过聚类分析确定影响粮库玉米品质的特定优势霉菌组合。3）研究环境生态因子对玉米中单一或优势霉菌消长规律的影响。4）模拟单一或特定优势霉菌在不同主要生态因子条件下的生长，分别构建其对应的预测模型。5）采用数学或图形等方法对构建的模型进行验证和评价。

One of the main factors influenced quality of the storage corn is mildewed. The advantage mold plays a decisive role. The changs of the advantage mold affects the quality of maize. There are disadvantages in these means for the safety of the storage, such as goals not clear, high energy consumption, drug residue and so on. To the microbial factors harmed quality of the storage corn, this project carries out the research about the prediction model of mold in corn by the predictive microbiology theory. It is very important theoretical value to ecologically store grain and ensure the safety of corn storage. . The important contents of the research in this project are as follows: 1) Study the diversity of mold in different regional corn, and analyse the bacterium group. 2) By clustering analysis, determining the dominant combination of mold influenced the quality of the corn in grain depot. 3) Study the change rules of single or advantage mold influenced by ecological factors of environment. 4) Constructing the corresponding forecasting model about the single or the dominant mold. 5) These models is validated and evaluation by mathematical method or graphics.
