生物降解渗水地膜在谷子上的应用效果研究

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。本试验从谷子生育期、光合特性、农艺性状、产量等方面进行研究生物降解渗水地膜对谷子的影响。结果表明：与露地播种相比，生物降解渗水地膜能提前谷子生育期3～5d，显著增加谷子灌浆期光合作用，提高叶片SPAD值，对谷子农艺性状作用明显，产量达到3885.69kg/hm2，较露地处理分别增加86.57%、32.63%，穗重、穗粒重增加显著。同时，生物降解渗水地膜在谷子抽穗开花以后要优于普通地膜，产量较普通地膜增加8.81%。可见，生物降解渗水地膜效果较好，可进一步在该地区推广应用。

Study on application effect of biodegradable permeable mulching film on millet

Abstract:In order to explore the application effect of biodegradable permeable mulching film on millet and further explore the production potential of millet. The effects of biodegradable permeable mulching film on millet were studied in terms of growth period, photosynthetic characteristics, agronomic characters and yield.The results show that: Compared with open field sowing, biodegradable water permeable mulching film could advance the growth period of millet by 3 ~ 5d, significantly increase photosynthesis at grain filling stage, increase leaf SPAD value, and significantly affect the agronomic traits of millet. The yield reached 3885.69kg/hm2, which was 86.57% and 32.63% higher than that of open field treatment, respectively. Spike weight and grain weight increased significantly.At the same time, the yield of biodegradable permeable mulching film was 8.81% higher than that of ordinary mulching film after heading and flowering.It can be seen that the effect of biodegradable permeable mulching film is good, which can be further popularized and applied in this area.
