正确地掌握早稻生产中的“三期”(播种期、移栽期、抽穗期)是为了通过稻作生产尽可能多地利用大自然热能资源,来提高稻作产量。历年来,我们九江地区有的单位和农户,由于没有掌握好早稻“三期”而造成了烂秧减产。例如九江市郊区仅有6万亩水田,1981年栽插1.6万亩迟熟品种,由于未采用覆盖栽培措施,提早播种,致使抽穗、扬花期受高温影响,损失稻谷44万斤;1982年也因早稻在没有覆盖的防护下播种偏早,烂种六万斤。而这些不应有的损失,往往还不为人们所重视。笔者根据几年来的苗情观察和本地气象资料,就如何掌握好早稻“三期”,谈几点看法。
To correctly grasp the “third period” (sowing, transplanting and heading date) in early rice production is to increase the output of rice by making use of natural thermal energy resources as much as possible through rice production. Over the years, some units and farmer households in our Jiujiang area have caused rotten seedlings to cut down because they failed to grasp the “third phase” of early rice. For example, only 60000 acres of paddy fields in the suburbs of Jiujiang City in 1981 planted 16000 acres of late-maturing varieties, because not covered cultivation measures, early sowing, resulting in heading, flowering period subject to high temperatures, loss of 440,000 pounds of rice; 1982 Because of the coverage of early rice under the protection of the premature, six kinds of rotten species. And these unnecessary losses often do not pay attention to people. According to several years of observations of the Miao and local weather data, how do I master the “Three Phases” of early rice?
