剥绒棉种经过泡沫酸脱绒、药剂包衣处理,使优良品种成为优质种子。全区40万亩棉田,近三年来全部推广了脱绒包衣种。实践证明,包衣种子粒饱满,种子含水率低,贮藏性能好,发芽势强,发芽率高,保苗效果好,具有促进生长发育的作用。田间出苗率比剥绒种高5～10%,表现为出苗早而齐,叶色深,出叶速度快,蕾铃期提早,单株结铃数增加,育苗移栽的每亩增产皮棉3～4公斤,达到了优质高效。但棉种经脱绒包衣后,变换了物相,由毛籽变成光籽,使种子表面机理出现了新 Stripped cashmere cotton foam acid off velvet, pharmaceutical coating treatment, the fine varieties to become high-quality seeds. The region 400000 acres of cotton fields, the past three years to promote all the velvet coating species. Practice has proved that the coated seeds full, seed moisture content is low, good storage performance, strong germination potential, high germination rate, seedling effect is good, with the role of promoting growth and development. The emergence rate in the field was 5 ~ 10% higher than that of the stripping fleece, showing early emergence and homogeneous foliage, dark leaf color, fast leaf emergence, earlier boll stage and increased number of bolls per plant. ~ 4 kg, to achieve high quality and efficiency. However, the cotton seed through the velvet coating, the change of phase, from the seed into light seeds, the seed surface mechanism appeared new
