摘要
为探明生物降解渗水地膜在谷子上的应用效果,进一步挖掘谷子生产潜力,开展了生物降解渗水地膜对谷子生长及产量的影响试验。结果表明,与露地处理相比,生物降解渗水地膜能提前谷子生育期3~5 d,显著增强谷子灌浆期光合作用,提高叶片叶绿素含量(SPAD值),对谷子农艺性状作用明显,穗重、穗粒重增加显著,产量达到3885.69 kg/hm2,较露地处理增加32.64%~86.57%。同时,生物降解渗水地膜处理在谷子抽穗开花以后要优于普通地膜处理,产量较普通地膜处理增加8.81%。可见,生物降解渗水地膜应用效果较好,可进一步在该地区推广应用。
In order to explore the application effect of biodegradable permeable mulching film on millet and further explore the production potential of millet,the test of effect of biodegradable permeable mulching film on growth and yield of millet was carried out.The results showed that,compared with open field treatment,biodegradable permeable mulching film could advance the growth period of millet by 3-5 d,significantly promote photosynthesis at grain filling stage,increase leaf chlorophyll content(SPAD value),and significantly affect the agronomic traits of millet.The spike weight and grain weight increased significantly.The yield reached 3885.69 kg/hm2,which was 32.63%-86.57%higher than that of open field treatment.At the same time,the treatment of biodegradable permeable mulching film was superior to the treatment of ordinary mulching film,and the millet yield increased by 8.81%.Therefore,the application effect of biodegradable permeable mulching film was good,which could be further popularized and applied in this area.
