水稻“三紧一晒”管水法,是指在水稻移植后至倒三叶伸展前的营养生长期间,进行三次紧泥(轻晒)和一次晒田。它是依据水稻叶龄而采取的间歇灌溉管水法。此法可协调地上部与地下部、个体与群体的生长发育,培养良好的水稻长相;可以调气、调温、调肥,满足稻株的生理需水与生态需水。实践证明,不论肥田瘦田,低田还是高田,早稻或晚稻,双季还是单季,采用“三紧一晒”管水法,都有不同程度的增产效果。我社双季稻单产能在4—5年内由603斤提高到
Rice “three tight one sun” tube water law, refers to the rice transplanting to the third leaf before stretching the vegetative growth period, the three tight clay (light sun) and a Shaitan. It is based on the age of the paddy rice to take intermittent irrigation pipe method. The method can coordinate the growth and development of the upper part and the lower part, the individual and the group, and cultivate the good rice appearance; and can regulate the air, temperature and fertilizer to meet the physiological water requirement and ecological water requirement of rice plants. Practice has proved that, regardless of fertilizer Tian lean, Takada or Takada, early or late rice, double or single season, the “three tight one sun” tube water law, have different levels of yield. Double-crop rice production capacity of our company increased from 603 pounds in 4 to 5 years
