Study on Optimal Sowing Periods for Early Rice Based on Climate Analysis:A Case Study of Keqiao,Shaoxing
摘要
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.关键词
