敦化市隶属吉林省延边朝鲜族自治州,是自治州内最大的农业市。属中温带湿润季风气候中的温凉区,昼夜温差大,有利于作物积累干物质;境内雨热同季,物产丰富,水、光、能资源充沛,独特的长白山冷凉气候十分有利于玉米、大豆的生长发育,生产出的产品适口性好,环境无污染,是吉林省重要的玉米、大豆生产基地之一。多年来,由于气候变化和原始的耕作方式,造成土壤径流损失较大,有效耕层逐年减少,犁底层逐渐加厚,形成地薄不打粮的现象(据测查,现在部分乡镇土
Dunhua City, under the Yanbian Korean Autonomous Prefecture in Jilin Province, is the largest agricultural city in the Autonomous Prefecture. It belongs to the temperate zone with moderate temperature and humid monsoon climate. The temperature difference between day and night is large, which is conducive to the accumulation of dry matter in crops. The rain and heat in the same season are rich in natural resources, abundant in water, light and energy. The unique cold climate in Changbai Mountain is very beneficial to corn. Soybean’s growth and development, to produce products with good palatability, environmental pollution, Jilin Province is an important corn, soybean production base. Over the years, due to climate change and primitive tillage, resulting in large loss of runoff, effective plowing decreased year by year, plow gradually thickening of the ground, the formation of thin ground does not hit the phenomenon of grain (according to the survey, now part of the township soil
