棉花栽培过程中使用甲哌鎓已很普遍,主要目的是协调棉株营养生长和生殖生长,塑造理想株型,实现增产增收。在棉花生产上使用甲哌鎓要注意以下几点。选择对象田三种棉田适合喷施甲哌鎓:一是土壤肥力较高或前期施肥量大且氮肥比例大,棉株营养生长过旺,有旺长趋势的棉田,包括地膜棉和麦后棉;二是品种株型松散,植株高大的棉田;三是种植密度过大、株行距配置不合理,有提早封行趋势的棉田。土壤肥力差、棉株长势弱的田块和干旱少雨时均不宜喷施甲
The use of mepi-onium in cotton cultivation has been very common. The main purpose is to coordinate the vegetative and reproductive growth of cotton plants, create the ideal plant type and increase the yield and income. The use of mepiquat in cotton production should pay attention to the following points. Field of choice Three fields of cotton suitable for spraying meperonium: one is higher soil fertility or pre-fertilization and a large proportion of nitrogen, cotton vegetative over-growth, there is a long trend of cotton fields, including cotton and wheat cotton membrane ; The second is the type of plant loose type, tall cotton plant; third planting density is too large, the row spacing is unreasonable, early closure trend of the cotton field. Soil fertility is poor, cotton plants grow weak fields and dry when it is not appropriate to spray A
