In the face of practical situation that the benefit of mulch-covered hole sowing of wheat was low, film-side drilling culture was adopted in place of mulch-covered hole sowing and a systematic study was made on the effects of 3 cultivation methods. The results show that the film-side drilling culture of winter wheat has the advantages of increasing temperature, promoting growth and development, collecting water and preserving moisture, bringing unavailable precipitation into effective utilization and largely increasing water productivity. It demonstrated extraordinary effect of taking care of seedlings and letting them live through the winter. The young panicle differentiation and active growing period was prolonged significantly. The percentage of earbearing tillers in the field, the number of grains per ear, thousand kernel weight and yield were 14.2%,16.8%,3.8% and 34.5% higher than those of uncovered drilling wheat respectively. It overcomes many disadvantages of mulch-covered hole sowing of wheat, reduces the production cost to some extent, increases net income by 1072.23 yuan per ha., or 35.7%, increases labor productivity and rate of return of material expense by 32.3% and 24.9% respectively.
