| Abstract: |
| In order to provide reference for the popularization and application of water-permeability plastic film mulching cultivation technology on foxtail millet in dryland, effects of water-permeability plastic film mulching on soil moisture, temperature and growth and development of foxtail millet in dry land were investigated on the study. In semi-arid area of central Gansu where annual rainfall is about 400 mm, the single factor randomized block design with open ground, common plastic film mulching, and water-permeability plastic film treatments were adopted and soil moisture content, soil temperature, and yield were measured at emergence, heading, and maturation stages in the experiment. The results showed that water-permeability plastic film with moisture permeable function enabled soil to absorb more water than common plastic film (the average soil moisture content of water-permeability plastic film is higher than the common plastic film in each growth period). Water-permeability plastic membrane and common plastic film mulching both increased soil temperature. However, due to the regulatory function of micropores in water-permeability plastic film, it was easier to have temperature increased at low temperatures and cause temperature reduced at high temperatures than the common plastic film. Compared with common plastic film, water-permeability plastic film treatment can improve agronomic traits and increase foxtail millet yield by 6.75%. |
