栽种烤烟、黄麻、苧麻,甘蔗和甜菜是收获其营养体,如叶片,麻皮、茎秆及塊根。实践证明,增施肥料、改进施肥方法后,这几种作物的增产效果特别显著。这几种作物的植株大都高大,生长繁茂,如施肥不足,就不能达到高产。目前栽种这几种作物,除施肥量一般不足外,各地偏重施用氮素肥料,磷钾肥施用很少或不施用。同时习惯基肥铺施,追肥撒施,不能发挥最大肥效。为了获得高额产量,提高产品品质,今后须结
Planting flue-cured tobacco, jute, ramie, sugar cane and sugar beet is the harvest of its nutrients, such as leaves, bark, stalks and roots. Practice has proved that, by increasing fertilizers, improved fertilization methods, these crops increase yield is particularly significant. These plants are mostly tall plants, growing lush, such as inadequate fertilization, they can not achieve high yield. Currently planted these kinds of crops, in addition to the general lack of fertilizer, the emphasis on the application of nitrogen fertilizers, phosphorus and potassium application with little or no application. At the same time, they are accustomed to using basal fertilizer and dressing, and they can not exert the most effective fertilizer. In order to obtain high output, improve product quality, the future must end
