| Abstract: |
| Considering the problems of artificial seeding, sealing film hole in the traditional plastic film mulching, this paper studied the self-puncture effect of six crops in sub-soil planting with film mulching. The results showed that the self-puncture ability of different crops in film mulching was different and the difference was extremely significant. The self-puncture ability of peanut and maize was the strongest, and their relative seedling ratio reached 0.85 and 0.78, respectively. Pumpkin was the weakest and its relative seedling ratio was 0.48. The factor strongly affecting the crop self-puncture was membrane overlying soil
thickness and the film thickness. In covering thickness of 0.008 mm thick film + membrane cover 2.0 cm thick soil, the crop self puncture effect with film mulching was the best. If the crop had a strong self-puncture ability, its self-puncture was affected relatively little by cover material change. The full stand t
ime of crops in sub-soil planting with film mulching was similar to control. |
