棉花高密度化学除草不中耕不整枝,是获得棉花高产、优质、低成本的一项重要技术措施。高密化除棉是:改早播为适时晚播;改人工中耕除草为化学除草不中耕;改常规稀植为高度密植;改晚打顶为早打顶、小打顶;改精细整枝打权为仅打正顶;改分散施肥、争“三桃满挂”为重施花铃肥、主攻伏桃;改立体利用光能为平面利用光能,充分发挥群体增产优势;改一年一熟为油、棉二熟。几年来,通过全省重点社队大面积示范
Cotton high-density chemical weeding does not cultivate not pruning, is to obtain high yield cotton, high quality, low cost an important technical measure. In addition to high-density cotton is: early sowing to timely late sowing; artificial cultivation of herbicides for chemical weeding does not cultivate; change to conventional thin planting for a high degree of close planting; late topping for the early topping, small topping; fine pruning rights As the only hit the top; to disperse the fertilization, the fight “three peaches full hanging” as the re-implementation of Huulan fat, the main Fuping; to change the three-dimensional use of light energy for the plane, give full play to the advantages of group production; , Cotton two cooked. In recent years, large-scale demonstration has been carried out by key provincial and municipal community teams
