黄河三角洲地区的利津、垦利、沾化等县及东营市,属黄河冲积平原,地势平坦,土质疏松,土层深厚,冬小麦是该地区主要粮食作物。但是长期以来,小麦产量低而不稳,亩产百斤左右,比所在地区(惠民地区)小麦平均单产低100多斤。造成小麦产量低而不稳的原因很多,但是从位于三角洲内的黄河农场看,即使在小麦品种和栽培技术变化不大的情况下,产量波动仍较大,这表明气象条件对该地小麦产量的影响是很大的。本文试图通过对该地历年小麦产量和气候资料的统计分析,从气象角度探讨该地区
The Yellow River Delta Lijin, Kenli, Zhanhua counties and Dongying City, belongs to the Yellow River alluvial plain, flat, loose soil, deep soil, winter wheat is the region’s main food crops. However, for a long time, the yield of wheat has been low and unstable, with a per-mu yield of about 100 kilos lower than the average yield of wheat in the area (Huimin). There are many reasons for the low and unstable wheat yield, but from the Yellow River Delta in the delta, there is still a large fluctuation in output even with little changes in wheat varieties and cultivation techniques, indicating that the meteorological conditions have a negative effect on the yield of wheat The impact is great. This article attempts to use the statistical analysis of wheat yield and climate data over the years to discuss the area from the meteorological point of view
