In 1987, we carried out large-scale spraying of medium and low molecular weight humic acid test in a winter wheat field in our group with a total spraying amount of 11,323 mu and remarkable stimulation effect. The tested humic acid was provided by the Turpan region chemical plant .Through five treatments, The amount of fertilizers to be treated for trial plots and tested varieties are as follows: (1) 10 mu of humic acid was sprayed on the aircraft and the experimental field was a continuous field of winter wheat with a variety of 75,144; (2) spraying potassium dihydrogen phosphate 200 Grams of + 500 grams of urea, the test was located in the seven and eight even. Varieties for the 704; (3) acres spraying potassium dihydrogen phosphate 200 grams + 500 grams of urea + humic acid 6 grams, the test ground in the triple and Five even,
