适时适量施好棉花花铃肥，充分满足花铃期对养分的需要，是夺取棉花早熟、优质、高产的关键。1．施用时间以看结桃情况为前提，看叶色变化为依据，桃、色结合就能准确地掌握施肥时间。看桃，就是要看到棉株基部能结牢1～2个大桃。棉花结了挑，表示棉花的生殖生长向优势方向转化
Appropriate amount of cotton bolls appropriate amount of fertilizer to fully meet the needs of the flower-ring nutrient is to seize the cotton precocious, high-quality, high yield the key. 1. Application time to see the peach conditions as a precondition to see leaf color changes based on the peach, color combination can accurately grasp the fertilization time. See peach, is to see the base of cotton plants can be a knot 1 to 2 big peach. Cotton knot pick, said that the reproductive growth of cotton to the dominant direction of conversion
