早稻播种育秧正处在冷暖空气交替频繁的早春季节.由于这个时期的天气,时晴时雨,忽冷忽热,很不稳定.因此,如何正确掌握季节,做到适时播种,育出壮秧,就显得特别重要.如果播种过早,由于温度过低,将严重影响出苗,出苗后遇上寒流,往往造成烂秧.因此,正确分析气候与早稻育秧的关系是很有意义的.一、烂秧的天气类型烂秧包括播种后出苗显青之前的“烂芽”和出苗显青之后的“死苗”两种情况.早稻播种育秧期,正是南北冷暖气团交替时期,每次冷空气南下,造成地面强烈辐射,温度急剧降低,或者形成静止锋,出现低温阴雨的天气.
Early rice planting and sowing is in the warm and cold air alternating early spring season .Because of this period of the weather, sunny when the rain, hot and cold, very unstable.Therefore, how to correctly grasp the season, timely sowing, breed strong seedlings , It is particularly important.If the sowing too early, due to the temperature is too low, will seriously affect the emergence, emerge after the cold, often resulting in rotten seedlings.Therefore, a correct analysis of the relationship between climate and early rice seedling is of great significance.A, Rotten seedling weather rotten seedlings include sowing before the emergence of significant green before the “rotten buds” and after the emergence of significant green “dead seedlings.” Early rice sowing seedling stage, it is alternating cold and warm air between the North and the South, each cold air South, causing strong radiation on the ground, a sharp decrease in temperature, or the formation of static front, the emergence of cold and rainy weather.
