根据实际情况制订科学的蔬菜生产计划,是保证市场供应,防止大量返销,减少国家经济损失的重要前提。而作为该项工作的基础——蔬菜上市量预测预报,对调整、规划蔬菜的合理种植,更显得十分重要。影响蔬菜上市量的因素很多,有农业气象中的最低温度、平均温度、降雨量、雨日、日照时数、辐射量等,还有人均收入、市场价格、瓜果销售量、食品消费量等。以上许多因素均具有不确定性,故用经验方法对蔬菜上市量进行预测就有一定的困难。为此我们以上海郊区黄瓜上市量和种植面积资料为基础,通过计算机寻找具有影响的气象
Making a scientific vegetable production plan according to the actual situation is an important prerequisite for ensuring the supply of the market, preventing a large amount of back sales and reducing the economic losses of the country. As the basis for this work - forecasting the amount of vegetables listed on the adjustment, planning the rational planting of vegetables, it is even more important. The factors affecting the amount of vegetables listed are many factors, such as the lowest temperature in agricultural meteorology, the average temperature, rainfall, rain days, sunshine hours, radiation, etc., as well as per capita income, market prices, fruit sales, food consumption, etc. . Many of the above factors are uncertain, so using empirical methods to predict the amount of vegetables listed has some difficulties. To this end, we based on the Shanghai suburbs cucumber listing volume and planting area data, through the computer to find influential weather
