| Abstract: |
| This paper studied the relationships of covering methods and wheat yield, agronomic characters based on the experiment of different covering methods in Weibei highland. Results were as follows: (1) wheat yield increased significantly when the grounds were covered with common plastic film, straw and common plastic film, straw and water-permeability plastic film. The yield of wheat was highest in DQF treatment, and reached 6 971 kg/hm2. Compared with no covering, under different covering matters and terms, the highest increase rate of wheat yield was 92.62% and the lowest increase rate was 23.16%; (2) Wheat yield in the treatments that grounds were covered with common plastic film, straw and water-permeability plastic film in the whole process were significantly higher than that in the fallow period; (3) Agronomic characters of wheat were improved greatly after the ground was covered with different materials, but the basi
c seedling number of wheat decreased in the whole-process mulching treatments. |
