摘要:

为应对全球气候变暖和农业生产方式变化带来的水稻早播风险,本研究以绍兴市柯桥区为例,开展了早稻适宜播种期研究。基于43 a农业气象观测资料和实地调查,设定机插和直播早稻的5个分期播种方案,分析不同播期下各生育阶段的农业气象灾害发生概率。研究结果表明,绍兴市柯桥区机插早稻的适宜播种期为3月下旬—4月上旬初,直播早稻的适宜播种日期为4月上旬—中旬初。该研究为气候变化背景下,指导种植户科学安排机插和直播早稻生产,实现趋利避害提供重要参考。

Abstract:

In the context of global climate warming and evolving agricultural practices, cases of premature sowing and cultivation in rice production have increased. This study focuses on Keqiao District, Shaoxing City, utilizing 43 years of observational data from the Keqiao National First-Class Agrometeorological Observation Station, combined with field surveys of current agricultural sowing practices. Five phased sowing schemes for machine-transplanted and direct-seeded early rice were developed. Analyze the probabilities of agrometeorological disasters occurring at different developmental stages for machine-transplanted and direct-seeded early rice under various sowing dates, and determine the suitable sowing periods for both machine-transplanted and direct-seeded early rice based on the principle of seeking advantages and avoiding disadvantages. The results showed that the suitable sowing period for machine-transplanted early rice in Keqiao, Shaoxing City is from late March to early April, and the suitable sowing date for direct-seeded early rice is from early April to early mid-April. This provides a scientific basis for farmers to reasonably arrange the production and planting of machine-transplanted and direct-seeded early rice, as well as to seek advantages and avoid disadvantages under climate change.
