河套地区的气候特点是,昼夜温差大,日照时间长,降雨量少,有利于甜菜糖分的形成和积累。实践证明,河套地区是发展甜菜生产的良好基地。但是随着种植面积的增加,甜菜含糖量则明显下降,75年和81年尤为实出,比六十年代下降1.7—2.8度,直接影响到制糖工业的发展。 甜菜含糖量的高低,除受品种、栽培技术、病虫害(实际上病虫害与气候关系甚为密切)等的影响外,与气候条件是有一定关系的。由于河套地区北靠阴山,南临黄河,区
Hetao climate is characterized by large temperature difference between day and night, long hours of sunshine, less rainfall, beet sugar is conducive to the formation and accumulation. Practice has proved that Hetao area is a good base for the development of sugar beet production. However, with the increase of planting area, the sugar content of sugar beet decreased obviously, especially in 75 years and 81 years, which was 1.7-2.8 degrees lower than that in 1960s, which directly affected the development of sugar industry. Beet sugar level, in addition to the species, cultivation techniques, pests and diseases (in fact pests and diseases and the climate is very close) and other effects, and climatic conditions have a certain relationship. As the Hetao area Yinshan north, south of the Yellow River, the district
