当前麦棉套作面积迅速扩大，给套种棉深施磷钾造成一定困难．致使棉花根系从深层土壤中得不到足够的磷钾养分，病株率增加，产量徘徊；部分棉田在挖土壤库存磷钾养分。本协作组在氮、磷、钾肥均有效的土壤上进行的麦、棉全程统筹平衡施肥技术试验结果表明，根据地力确定的适量的磷、钾肥，在种麦前耕地时一次深施作基肥，是麦棉优质、高产、高效益的适宜简化施肥技术。国内外尚未见同类报导。
The current area of wheat cotton cover rapidly expanding, to inter-planting cotton deep phosphorus and potassium caused some difficulties. Resulting in cotton roots from deep soil can not get enough phosphorus and potassium nutrients, plant disease rate increased, output hovering; some cotton fields in the soil phosphorus and potassium nutrients. The results of this experiment show that the appropriate amount of phosphorus and potash fertilizers determined according to the soil fertility are deeply applied as basal fertilizer during the cultivation of wheat before planting. Is the cotton quality, high yield, high efficiency suitable for simplified fertilization technology. No similar reports have been seen at home and abroad.
