江苏农垦小麦超高产栽培实践

Practice on Super-high Yield Cultivation of Wheat in Jiangsu Agricultural Reclamation

针对江苏地区稻麦两熟条件下,影响小麦高产茬口衔接紧张、农机农艺配套等主要因素,江苏农垦多年来持续开展了小麦超高产技术研究和示范,高产攻关田实现了单位面积产量从600 kg/667 m2到800 kg/667 m2的新跨越。本文集中考察了小麦争早、高质量农机作业、稳产高产等关键指标,详细总结了种子处理、土壤深松耕翻、不同土质适应化播种作业、沟壁播种扩边增效、全程数智化管理、抗逆保绿防早衰等小麦超高产栽培的主要技术措施,为规模化、集约化生产条件下小麦稳产、高产、高效提供技术支持。

In response to the main factors affecting wheat high yield,such as tight crop connection and agricultural machinery and agronomic matching,under the rice-wheat double cropping system in Jiangsu Province,Jiangsu Agricultural Reclamation has continuously carried out research and demonstration on super-high yield wheat cultivation techniques,and the super-high yield demonstration fields have achieved a new leap from 600 kg/667 m2 to 800 kg/667 m2.This paper focused on the key indicators of early wheat planting,high-quality agricultural machinery operations,stable and high yield,and summarized in detail the main technical measures for super-high yield wheat cultivation including seed treatment,deep soil loosening and tillage,adaptive sowing operations for different soil types,ditch wall sowing to expand edges and increase efficiency,full-process digital and intelligent management,stress resistance,green protection,and prevention of premature senescence.It provides technical support for stable yield,high yield and high efficiency of wheat under large-scale and intensive production conditions.
