早稻在我省粮食生产中占有重要的地位,但所处生长季节的气候条件,却是起伏多变。前期常因低温冷害,造成烂秧,发僵或迟发:中期梅雨连绵,日照不足,影响幼穗发育,造成颖花退化和秕谷增加;后期则常因高温逼熟,粒重减轻,影响产量。各项多变的气候因子,对早稻产量构成影响极大,是早稻持续高产亟需探索的一个重要因素。研究早稻生长期间的气候特征和气候因子对 Early rice occupies an important position in the grain production in our province, but the climatic conditions in the growing season are ups and downs. Premature chilling, resulting in rotten seedlings, stiff or late: the mid-May rainy season, lack of sunshine, affecting the development of young panicles, resulting in reduced spike and Hysterical Valley; late often due to high temperature ripening, weight loss, the impact of Yield. The ever-changing climatic factors have a great impact on the yield of early rice. It is an important factor that needs to be explored in the early rice’s continuous high yield. Study on climatic characteristics and climatic factors during early rice growth
