根系是作物活跃的吸收器官和合成器官 ,根量、根系生理活性与地上部叶片光合作用、生长发育密切相关 ,用 TTC还原强度、根系吸收面积在一定程度上可表示根系的生理活性。棉花是直根系作物 ,种植制度对其根系影响较大 ,有关一熟棉根系的生理特性及栽培措施对根系生长与产量形成
The root system is an active organ of uptake and synthesis of crops. The root physiological activity and root physiological activity are closely related to photosynthesis and growth and development of above-ground leaves. The TTC reduction intensity and the root absorption area can express the physiological activity of the root system. Cotton is a straight root crop, and the planting system has a great influence on its root system. Physiological characteristics and cultivation measures of root system of a cotton root cause great effects on root growth and yield formation
