According to the post series statistic data of ailment spikes percentage and the model set up through GM(1, 1) calamities mapping, the authors carried out the study on the State Farm 854 in Heilongjiang Province providing a model of time function on long period forecasting of wheat scab (1973-1982).P~(o)(t)=147.15133e~(0.08294(t-1)-1.06792e~(-0.37533(t-1)-135.08341After careful examining the precision of model reaching its high rate, the past record its precision rate during 1973-1982 was 100%, and the forecasting results we got during 1983-1986 proved to be conformed with facts completly.The forecasting value of 1987-1991 is also given in this report. It will provide the policy-makers with very useful information to help them control the wheat scab.

本文应用灰色系统理论对小麦赤霉病的长期预测方法进行了研究。作者根据黑龙江省八五四农场小麦病穗率的历史统计数据列(1973-1982年),经灾变映射建立GM(1,1)模型,并给出了小麦赤霉病长期预测的时间函数模型: p(t)=147.15133e~(0.08294(t-1))-1.06792e~(-0.37533(t-1))-135.08341经检验,模型的精度高,回测1973-1982年的结果,拟合率达100%;对1983-1986年的预測结果,全部与实况吻合。本文又计算出1987-1991年的预测值,这将为小麦赤霉病的研究与防治,提供有益的信息。

Construction projects must be handle economic appraisal and risk compare of all investment decisions. We can make a reasonable investment decision. With having poor technical, We cannot successfully carry on investment risk analysis precisely so far.

The history and current situation of wheat mildew occurrence and its damage in china were briefly introduced, and the rampant basis of the biology and epidemiology for the mildew was reviewed in this paper. Based on the principle and methods of plant epidemiology as well as a large amount of statistical data cited, the synthetic action of the seven causes are believed to be responsible for the increasingly severe wheat mildew in china. They are as follows: the lack of resistance in the grown varieties at present, overboundance or impropriety in the application of nitrogen fertilizers, changing of cropping system to the rice—wheat one or intercropping of wheat with cotton in larger areas, enormous increasing in the irrigation areas of farm land, higher densities of wheat plants in the fields, weather warming and unwise policy decision due to the limitation of the knowledge on the disease. It was predicted that the disease may be more severe in future,by pointing out that some favourable conditions for it can't be altered in china. Some countermeasure suggestions for controlling the mildew were presented.

本文首先介绍了我国小麦白粉病发生危害的历史和现状;评述了小麦白粉菌猖獗的生物学和流行学基础。然后,根据植物病害流行学原理,列举了大量的历史统计数据,运用了数学模型的分析方法,从理论上分析阐明了全国种植的小麦品种抗性退化或丧失,氮肥重施偏施,耕作制度变化,农田灌溉面积巨增,田间小麦密度加大,大气候变暖以及人们认识上的局限性所致的决策上失误等原因的综合作用,造成了小麦白粉病日趋严重的局面。进而预测未来该病仍呈上升趋势。最后,提出了短期和长期的对策建议。
