| Abstract: |
| Field experiment was used to investigate the effects of plastic film mulching and straw mulching on the growth, dry matter distribution and nutrient uptakes of maize.In the test year, there was plenty of rainfall during the maize growth period but only a little at the early stage.Biomass and yield of maize were improved due to straw mulching or plastic film mulching.Maize NUE was improved as well.The nitrogen uptake of maize with mulching treatments was higher than that without mulching (CK) , while nitrogen remaining in the leaves was also higher, compared to no mulching.Mulching had no effect on the distribution of dry matter and harvest index of maize. |
