早稻从分蘖高峰到抽穗前,是生长发育过程中的一个重要时期。它一方面进行以茎秆伸长为中心的营养生长,另方面进行以穗分化为中心的生殖生长。这时大田管理,要针对早稻的生育特点,以保蘖攻穗为主攻方向,正确处理好促与控的关系,达到营养生长和生殖生长协调,植株生长稳健,幼穗分化正常,既不疯长过头,又不脱力早衰。

Early rice from tillering peak to heading, is an important period in the process of growth and development. On the one hand, it conducts vegetative growth centered on stem elongation and on the other hand reproductive growth centered on panicle differentiation. At this time, field management should aim at the characteristics of early rice’s development, take the tillering ear as the main direction, correctly handle the relationship between promoting and controlling, achieve the coordination of vegetative and reproductive growth, plant growth is healthy, panicle differentiation is normal and neither is too long Excessive, but not decubitus premature aging.
