在我省早稻播种期间,常常迂遇到冷害,俗称春寒。春播期的冷害,对早稻播种极为不利,严重的春寒可导致全省性的烂种烂秧,既损失良种,又延误农时,影响二晚生产。因此了解我省历年春播期间的冷害情况,对于科学地安排全年农业生产具有非常重要的意义。现根据我省历年气象资料,就早稻播种期的冷害及其防御问题,谈点个人看法以供参考。 During the sowing of early rice in our province, it often leads to cold damage, commonly known as cold spring. The chilling injury in spring sowing is extremely unfavorable to the sowing of early rice. Severe cold spell can cause rotten seedlings of the whole province, which will not only lose the elite seeds, but also delay agricultural production, affecting the production of two nights. Therefore, it is very important for us to understand the chilling injury during the spring seasons in our province for scientifically arranging the annual agricultural production. Now according to the calendar year meteorological data in our province, on the chilling injury of early rice and its defense issues, talk about personal views for reference.
