In 1983 the county 6O5 science and technology households, mu of wheat field test results and found that the proportion of nitrogen and phosphorus accounted for 6% of the area of ?? testing, these plots seriously hamper the improvement of wheat yield. Accordingly, the combination of perennial trials and characteristics of wheat needs fertilizer to promote wheat formula fertilization according to local conditions, the next year acres of wheat increased by 40-100 kg, the yield was 9,8-28.6%, net income per acre increased by 6-36 yuan.
