Abstract:
Weather and soil conditions affect the operation quality and production efficiency of maize soil preparation, sowing and harvesting, as well as maize growth, yields and costs. The agricultural meteorological factors in the Northeast of China are soil moisture, soil thawing depth, temperature, precipitation and wind. According to the effect of weather and soil conditions on maize soil preparation, sowing and harvesting, this paper developed the meteorological suitability functions of the farm work by using fuzzy membership function, and defined the agricultural meteorological index, then the comprehensive meteorological suitability evaluation model was constructed by using the weighted sum method. The result of examination showed that the model and index are workable and can be used in the meteorological suitability evaluations on the farm work. On the basis of temperature and precipitation forecasts and other meteorological elements, the model can also be used in the forecast of meteorological suitability of the farm work.
