昌图县处于辽宁省北部,有辽北平原之称。地理上位于北纬42°35″—43°29″。作物生育期≥10℃活动积温2990℃,降水量540.2毫米。无霜期154天。自然条件有利发展甜菜生产。但十几年来,一直是单产不平衡,含糖率不稳定。全县亩产最高的达2,000-5,000公斤,含糖高的达16—17％。然而低产区,亩产仅1,000多公斤,含糖不足13％。随着甜菜种植面积的不断扩大,为全面实现高产高糖,我们连续三年进行了多方面调查和试验,就调查和试验结果,初步总结出七项提高产量和含糖的栽培措施。
Changtu County is located in the northern part of Liaoning Province, known as the Northern Liaoning Plain. Geographically located at latitude 42 ° 35 “-43 ° 29”. Crop growth period ≥ 10 ℃ active accumulated temperature 2990 ℃, precipitation 540.2 mm. Frost-free period 154 days. Natural conditions conducive to the development of sugar beet production. However, over the past decade, it has been characterized by an imbalance in yields and an unstable sugar content. The county’s highest yield of 2,000-5,000 kg per mu, high sugar content of 16-17%. However, in low-yielding areas, only over 1,000 kg per mu and less than 13% sugars are produced. With the continuous expansion of beet planting area, we conducted various investigations and experiments for three years in a row to fully realize high-yield and high-sugar production. Based on the survey and test results, seven preliminary cultivation measures were put forward to increase yield and sugar content.
