惊蛰至清明是我省早稻播种期。这期间天气渐渐回暖,但因冷空气势力仍然相当强盛并时而南侵,所以回暖常不稳定,往往出现春寒天气,对播种育秧造成危害。长时间的春寒则可导致严重的烂种烂秧,既损失良种,打乱早稻的计划安排;又耽误季节,影响晚稻的按时栽插,增加遭遇寒露风危害的机率。因此,掌握春寒规律,对于适时播种,避免烂种烂秧和夺取早晚稻两季丰收都有重要意义。 Jingzhe to Qingming is the province of early rice sowing period. During this period, the weather gradually warmed up. However, due to the fact that the cold air force is still quite strong and sometimes southward infested, the warming is often unstable and the cold weather often occurs, posing a hazard to sowing seedlings. Long-term cold spring can lead to serious rotten seedlings, both loss of seeds, upset the planned arrangements for early rice; also delayed the season, affecting the timely planting of late rice, increasing the chances of encountering cold dew. Therefore, mastering the law of spring cold, timely sowing, to avoid rotten seedlings and seize the harvest of both morning and evening rice is of great significance.
