棉花养分供应以纵向输送为主，横向输送为次。表现在棉花成铃特点上，则是近主茎的内围果节成铃率较高，远主茎的外围果节成铃率较低。因此在栽培技术上，应发展纵向结铃，使植株多长果枝，控制横向结铃，少长果节。
Nutrient supply to the main longitudinal transmission of cotton, horizontal transport times. Performance in cotton boll features, it is near the main stem of the inner fruit section boll rate is higher, the main stem of the peripheral fruit bolls rate is low. Therefore, cultivation techniques should be developed longitudinal bell, the plant how long fruiting branches, the control of horizontal bell, less fruit section.
