Study on Balanced Fertilizer in Wheat Growth in Shajiang Black Soil

The field trial was conducted, which studied the wheat balanced fertilization of high-yield and high-efficiency. The result showed that applying zinc had remarkable effect on increasing production on the basis of cooperating with nitrogen and phosphate fertilizer, and wheat yield surpassed that from peasant habital fertilization which applied enormous organic manure. The balanced fertilization could promoto wheat growth, improve economic properities, notably increase the content of alkli-nitrogen, available phosphorus and potassium in soil, and fertilize the soil. It laid a foundation for crop high yield.
