种好是基础,管好是关键。要夺取后季稻高产,在大田管理上,除了掌握前期早发“一轰头”,还必须抓好中后期的稳长与活熟,这一点已为多年来的生产实践所证明。现就这个问题谈谈我们的认识。一、控中期稳长,促根壮秆攻大穗后季稻从无效分蘖出生到抽穗前,是旺根长叶、壮秆长穗的营养生长和生殖生长的并进时期,也是决定穗多穗大的关键时期。从园秆拔节、幼穗分化开始,稻苗由营养生
Good is the foundation, management is the key. To seize the high yield of the latter quarter of rice, in field management, in addition to grasping early “head-on” early in the early stage, we must also grasp the long-term stability and livelihood in the mid-to-late period. This is evidenced by years of production practice. We are now talking about our understanding of this issue. First, the control of the medium-term stable and promote strong stalks large spike after the end of rice from the ineffective tillering to heading, is the root of long leaves, strong stalk long spike vegetative and reproductive growth of the merger period, but also determine the panicle more panicle Big critical period. From the stalk jointing, spike differentiation, rice seedlings by the nutrition students
