我社地处信丰县北部,属“亚热带湿润气候”。在早稻插秧后春末夏初期间,常受冷暖气团的交替影响,天气变化无常,往往形成低温阴雨天气,使早稻生长发育受到阻碍,甚至产生死苗死蘖,诱发“座蔸’,形成僵苗,影响产量。因此,防御五月低温冷害,保护早稻正常生育,是确保早稻高产丰收的一个重要课题。笔者根据近几年来的调查和试验资料,撰写此文,拟就五月低温对早稻返青、分蘖的影响及其防御补救措施作一初步探讨。 Our company is located in northern Xinfeng County, a “subtropical humid climate.” During the early spring and early summer after the early rice transplanting, it is often affected by the alternation of cold and warm air mass. The weather is often unstable and often forms cold and rainy weather, which hinders the growth and development of early rice and even produces dead and dead plants and tilts, inducing “seatbacks” Therefore, to prevent cold damage in May and protect the normal fertility of early rice is an important issue to ensure high yield and yield of early rice.According to the investigation and test data in recent years, the author of this article, to be May low temperature on early rice Greening, tillering and their defensive remedies for a preliminary discussion.
