我省南部和沿江地区实行双三熟制栽培,由于全年生育期偏短,后季稻必须采用40～60天较长秧龄的秧苗,加上育秧期间正值梅雨季节,气候温暖,日照不足,所育秧苗一般偏高.群众采用严格控制肥水的办法,抑制秧苗的生长,但往往效果不理想,且秧苗素质差,移栽后返青活棵慢,分蘖少.采用两段育秧方法,虽然能控制秧苗生长,显著改善秧苗素质,但花工费事. In the southern part of our province and in the Yangtze River area, double-three-ripening cultivation is carried out. Due to the short growth period throughout the year, the post-season paddy must adopt the seedlings with longer seedling ages of 40-60 days, plus the positive rainy season during the seedling growing season, , The seedlings raised are generally high.The masses use strict control of fertilizer ways to inhibit the growth of seedlings, but often ineffective, and the poor quality of seedlings, transplanting live green trees slow, less tiller.Using two methods of seedlings, though Can control the seedling growth, significantly improve the quality of seedlings, but spend labor.
