麦茬移栽稻生育中期烤田技术研究初报

从烤田始期、烤田历时天数两个关键烤田要素着手研究，初步提出了麦茬移栽稻生育中期烤田技术的定量化指标。研究表明：烤田始期指标为田间茎蘖数等于计划穗数，即“够苗烤田”为宜；烤田历时天数宜掌握在１４天左右。并从稻作生产实际操作的角度，粗浅地讨论了灵活应用定量化指标的原则。

A Preliminary Study on the Midsummer DrainageTechnique in Middle Growth Period of Rice after Wheat

The quantitative index about the rice midsummer drainage after the wheat in the middle growth period was put forward preliminarily on basis of the two key elements of the midsummer drainage:initiation and days of duration the index of initiation is the date at which the number of the tillering is equal to that of the planned spikes,that is,its good to drain when there are enough tillers in the field.The fitting index of the duration is about 14 days.The principle how to use the index flexibly was also discussed from the view of the practice operation in the rice production.
