通过对棉花单位叶面积负载的生殖器官量的研究结果表明：较高的叶面积载荷量［以单位叶面积负载的果节数（个／ｍ２叶）、结铃数（个／ｍ２叶）及生殖器官干重（ｋｇ／ｍ２叶））能够促进棉花群体叶片光合强度提高和养分向棉铃输送增多，因而群体成铃数增多，产量提高。同时由剪叶、疏蕾试验揭示了，当群体叶面积系数控制在适宜范围内，可通过提高叶面积载荷量使产量进一步上升，群体叶面积系数过大时，通过减少叶面积，提高叶面积载铃量可以使产量增加。而当叶面积过小时，虽叶面积载荷量增大，但终因光合面积太小，产量下降，因此叶面积载荷量可作为反映棉花群体源库是否协调及改进栽培技术的依据。
The result of the research on the amount of reproductive organs loaded on the leaf area per unit area of cotton indicated that the higher leaf area load [the number of fruit nodes per unit leaf area (leaves per m2 leaf), the number of bolls (leaves per m2 leaf) The dry weight of reproductive organs (kg / m2 leaf) could promote the increase of photosynthetic intensity and the increase of nutrient delivery to cotton bolls in cotton population, which resulted in the increase of bolls and the increase of yield. At the same time, the results of leaf pruning and bud pruning showed that when the leaf area coefficient of the population was controlled within the proper range, the yield could be further increased by increasing the leaf area loading. When the population leaf area coefficient was too large, the leaf area was increased and the leaf area was increased Carrying volume can increase production. However, when the leaf area is too small, although the leaf area load increases, but eventually the photosynthetic area is too small, yield decline, so the leaf area load can be used as a reflection of the cotton pool source library is coordinated and improved cultivation techniques.
