摘要
为探究不同颜色降解膜覆盖对制种玉米产量及水分利用效率的影响,于2024年在新疆维吾尔自治区开展田间试验,共设5个处理:白色普通地膜(CK)、黑色普通地膜(BP)、黑色生物降解膜(BD)、白色生物降解膜(WD)和白色生物降解膜+膜上覆土(WDC),对比分析5种不同地膜覆盖处理对土壤水分、温度、制种玉米产量及水分利用效率的影响。结果表明,玉米各生育时期土壤水分含量表现为BP>BD>WDC>WD>CK,其中BP和BD的保水效果尤为突出。全生育期CK的土壤温度最高,其全天土壤平均温度比其他处理高0.2~2.0℃;BP和BD处理土壤温度次之。WD处理白天土壤温度较BD提高0.1~0.7℃;但其夜间保温效果减弱,较BD降低0.2~0.8℃。与CK相比,BP处理的产量增加16.64%,水分利用效率提高19.01%;在降解膜覆盖条件下,BD处理较CK增产6.96%,水分利用效率较CK显著提高12.42%;WD和WDC处理的产量和水分利用效率与CK间无显著差异。可见,与白色普通地膜相比,黑色普通地膜覆盖显著提升了制种玉米的产量和水分利用效率,而黑色降解膜、白色降解膜覆盖处理在产量上无显著变化。
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.
