Chemical defoliants are applied to about 40% of the U.S. Cotton acreage as a harvest-aid practice prior to machine picking. Raw cottons derived from defoliated and nondefoliated fields were examined for content of bract and leaf trash Chemical defoliation lowered, but did not remove, leaf as a major trash component. The content of bract was unaffected by this harvest-aid practice. The histamine content in green leaf trash was 10X that found in nongreen leaf trash.
作为机械采摘前的一项收获辅助措施,化学脱叶剂被应用于美国约40%的棉花种植面积。对来自已脱叶和未脱叶田地的原棉进行了苞叶和叶屑含量检测。化学脱叶降低了但并未去除作为主要杂质成分的叶子。苞叶的含量不受这项收获辅助措施的影响。绿叶屑中的组胺含量是非绿叶屑中组胺含量的10倍。
