连作晚稻插秧后往往发生败苗,这就延缓了水稻的生长,使早插不能早发,影响水稻产量,因此针对败苗原因,研究防止败苗的技术措施,使连作晚稻能早返青、早发裸,有利于夺取高产。根据浙江省农科院水稻所晚稻栽培组的晚粳稻育秧拔秧方法试验结果表明,败苗程度的轻重和秧苗的带根量呈极显著的负相关(r=-0.8454)。为了使 Even for late rice seedlings after transplanting often defeat seedlings, which delayed the growth of rice, so early plug can not be early onset, affecting rice yield, so the reason for defeat seedlings, to study the technical measures to prevent defeat seedlings, Bare naked, help to seize high yield. According to the test of late-season rice seedling-raising and seedling-raising method in the late rice cultivation group of Zhejiang Academy of Agricultural Sciences, it showed that there was a significant negative correlation (r = -0.8454) between the severity of seedling damage and the rooting amount of seedling. because
