| Abstract: |
| This study aimed to investigate the effects of different colored degradable film mulching on yield and water use efficiency of seed production maize. The experiment was set up in Xinjiang in 2024 with five treatments: white normal film (CK), black normal film (BP), black biodegradable film (BD), white biodegradable film (WD), and white biodegradable film + topsoil covering (WDC). The effects of five different mulch treatments on soil moisture, temperature, yield and water\|use efficiency of seed production maize were comparatively analyzed. The results showed that across all growth stages, soil water content exhibited the following pattern: BP>BD>WDC>WD>CK, with BP and BD demonstrating particularly outstanding water retention capabilities. Soil temperature under the CK during the whole grwoth period was the hightest, and its daily average soil temperature was 0.2-2.0℃ higher than that under other treatments, followed by BP and BD treatments. Soil temperature under the WD treatment were 0.1-0.7℃ higher than that under BD during daylight hours, but the effects of thermal retention were weakened at night. Soil temperature of WD was 0.2-0.8℃ lower than that of BD. Compared with the CK, the BP treatment yielded a 16.64% increase in crop production and a 19.01% improvement in water use efficiency. Under degraded film mulch conditions, the BD treatment achieved a 6.96% higher yield than the CK treatment, with water use efficiency significantly enhanced by 12.42%. There was no significant difference in yield or water use efficiency between the WD and WDC treatments and the CK treatment. It is evident that, compared with white normal film, black normal film significantly enhanced both seed maize yield and water use efficiency. However, black biodegradable film and white biodegradable film showed no significant difference in yield compared with standard white normal film. |
