连阴雨天气条件下小麦迟播抗灾栽培策略调整及成效

Adjustment of Cultivation Strategy to Reduce the Negative Impact of the Delay of Wheat Planting Due to Continuous Rainy Weather in Gaoyou City and its Effect

2016年江苏高邮市秋收秋种遭遇了历史罕见的连阴雨天气,水稻收获严重偏迟导致小麦大面积延迟播种。为抢秋播进度,全市积极采取改耕翻盖籽为浅旋一次性播种,改人工撒播为机械播种,改适期半精量播种栽培为迟播独秆栽培的"三改"技术措施,力争增加小麦播种面积。应用"两降一增"肥料运筹策略,采取机械适墒镇压、适度化控促壮等抗灾措施,促进苗情迅速转化,小麦生产在灾年仍取得了丰产丰收。

In 2016, Gaoyou City in Jiangsu Province met exceptionally continuous rainy weather, resulting in the delay of wheat sowing in a large area. In order to reduce its negative impact on wheat production, three measures were taken to adjust wheat sowing techniques, which enabled farmers to speed up wheat planting and increasing the wheat planting area in autumn. Adjusted cultivation techniques also included the application of ＂two drops and one increase＂ fertilization strategy, adopting the method of mechanically compacting soil to control soil moisture, and applying suitable chemicals to regulate plant growth and promote seedling development.By using these adjusted cultivation techniques, farmers in Gaoyou City still achieved the goal of a high yield of wheat despite bad weather conditions.
