要使棉株健壮生长,必须从苗期管起.棉苗的衰旺,对以后的控制过程和生长发育有决定性的作用.从现蕾开始,营养生长和生殖生长开始发生矛盾.这时正是普遍灌水.施肥时期,水、肥供应过多或不足,都会破坏两者的协调.而两者的协调发展,又是保证早熟丰产的关键.所以,管理措施要看天、看地、看苗情决定,不能机械地按既定的日程进行.现根据陆地棉费字108品种试验结果,结合在大面积样板田的观察与管理,初步提出看苗管理的生长发育指标和生理指标及采取的相应措施,以供参考.
To make the cotton plant grow robustly, it must be controlled from the seedling stage.The seedling’s vigorous growth has a decisive effect on the control process and growth and development.From the beginning of budding, the conflict between vegetative growth and reproductive growth began. Is widespread irrigation. Fertilization period, water, fertilizer supply is too much or insufficient, will undermine the coordination between the two. The coordinated development of both, but also to ensure that the key to early maturity and high yield. Therefore, management measures depends on the weather, look, see According to the test results of cultivars of cultivars in Fujian Province, combining with the observation and management of a large area of sample plots, the growth and development indices and physiological indices of seedling management are initially proposed and taken Corresponding measures for reference.
