三年小区试验和大面积示范表明，发展畜牧、增施有机肥，可使土壤有机质和土壤全氮增加。水稻优化施肥，薯、麦配方施肥，调整氮、磷、钾比例，改变当地氮素投入大于产出、磷素基本平衡、钾素亏损较大的局面，并能提高氮素利用率，增加产量，节省肥本。合理使用植物营养素，可使甘薯、小麦、水稻、花生、大豆诸作物增产。 Three years of district experiments and large-scale demonstration showed that the development of livestock husbandry and organic manure increased soil organic matter and soil total nitrogen. Rice fertilization, potato and wheat formula fertilizer, adjust the proportion of nitrogen, phosphorus and potassium, change the local input of nitrogen is greater than the output, the basic balance of phosphorus, potassium loss greater situation, and can improve nitrogen utilization and increase production Save fertilizer. Rational use of plant nutrients, sweet potato, wheat, rice, peanuts, soybeans and other crops yield.
