白城地区位于吉林省西部,面积为45,700平方公里。地形和地理位置对全区气候影响十分明显,是典型的大陆性季风、半干旱气候区。春秋干旱多风,夏季高温多雨,冬季寒冷少雪,十年九旱成为发展农业生产的限制性因素,尤其是春旱对农业生产威胁很大。它不仅影响春播保全苗,而且还影响着种子、肥料、耕作栽培等增产措施作用的发挥,致使粮食产量单产不高,总产不稳。因此,研究分析本地区干旱的成因和抗旱耕作保苗技术,建立符合本地区自然特点的科学的土壤耕作制,对白城地区实现农业现代化是十分重要
The Baicheng area is located in the western part of Jilin Province with an area of 45,700 square kilometers. Terrain and geographical location of the impact of the region’s climate is very obvious, is a typical continental monsoon and semi-arid climate zone. Spring and autumn arid and windy, hot and rainy in summer, cold and snowy in winter, ten years nine drought has become a limiting factor in the development of agricultural production, especially in the spring drought on the threat of agricultural production. It not only affects the protection of spring seedlings, but also affects the exertion of stimulation measures such as seeds, fertilizers and cultivation and cultivation, resulting in low yield of grain yield and unstable output. Therefore, it is very important for Baicheng to realize agricultural modernization in Baicheng in order to study and analyze the causes of drought in this area and the seedling-saving techniques of drought-resistant cultivation and establishment of a scientific soil cultivation system in line with the natural characteristics of the region
