阜新市地处辽宁西北部,无霜期150d左右,4-9月份降雨量450mm左右,蒸发量1375mm,常年≥10℃积温3300℃左右。属于一季有余两季不足的旱作农业区。文章通过近几年对抗旱耕作的多种栽培试验研究总结,提出了适于阜新市推广的抗旱耕作技术措施,包括品种选择、地膜覆盖、少耕免耕、节水灌溉、利用种衣剂和抗旱剂、改良和培肥土壤,增加土壤的抗旱性等6个方面。
Fuxin City is located in the northwestern Liaoning, frost-free period of 150d or so, from April to September rainfall of about 450mm, evaporation 1375mm, perennial ≥ 10 ℃ accumulated temperature of about 3300 ℃. Belong to more than one season more than two quarters of dry farming areas. Based on the summary of various cultivation experiments on drought-resistant tillage in recent years, the paper put forward some technical measures to promote drought-resistant tillage in Fuxin city, including variety selection, mulching, tillage and no-tillage, water saving irrigation, Drought-resistant agents, soil improvement and fertilization, increased soil drought resistance and other six aspects.
