欣荣优5号高产栽培与气候条件研究

Study on Climatic Conditions for High Yield Cultivation of Xinrongyou 5

研究了杂交早稻欣荣优5号高产栽培的适宜气候条件,提出该水稻新品种的最佳播种期为3月下旬,最佳抛载期为4月中下旬,同时提出了在孕穗抽穗、灌浆成熟期以防止高温逼熟为主的技术措施,旨在为该品种的大面积推广且达到高产、稳产提供技术参考。

The suitable climatic conditions for high yield cultivation of early hybrid rice Xinrongyou 5 were studied.It was suggested that the best sowing period of the new rice variety was late March and the best scatteredplanting period was mid-late April.Meantime,the main technical measures to prevent high temperature from forcing ripening in the booting and heading stage and grain-filling stage were put forward,in order to provide the technical reference for large area promotion and high and stable yield of the variety.
