棉花高产是运用综合栽培技术的结果。高产棉田应适当控制株高,又要多留果枝(18层左右),较好地利用纵向空间,压缩每台果枝节数(平均不过4节),控制封行过早,多增内围铃,减少外围和无效蕾、铃,保证亩有总果节数24～26万个,既有利于抓亩铃数,又可增铃重,实现高产就有可能。但要造成这样一个高产群体结构,光靠常规栽培技术,如疏忽一环,就有可能出现被动,这就必须配合使用生产调节剂,以弥补常规措施的不足,来协调棉花营养生长和生殖生长的矛盾,为高产创造条件。
High-yield cotton is the result of the use of integrated cultivation techniques. High yield cotton field should be appropriate to control the plant height, but also to stay fruit branch (about 18), make better use of longitudinal space, compress each fruit branch number (average but 4), control the sealing line too early, Reduce the external and ineffective buds, bell, mu total number of sections to ensure that 240,000 to 260,000, is conducive to grasping the number of acres of bell, but also boll weight, high yield is possible. However, in order to create such a high-yielding group structure, it is possible to passively adopt routine cultivation techniques, such as negligence, which must be accompanied by the use of production regulators to compensate for the lack of conventional measures to coordinate the vegetative and reproductive growth of cotton Contradictions, create conditions for high yield.
