利用室内模拟试验和田间试验对抚顺研制的两种液态地膜试样品“F1”和“F2”对土壤物理性状的影响和在冬小麦的应用效果研究。结果表明:液态地膜可增加水稳性团粒和土壤稳定性熵(QS),降低土壤容重,增加土壤孔隙度,饱和导水率成倍增加,有利土壤蓄水保墒;可提高冬小麦的产量,产量随着用量的增加而增加,最高可达6.5%;产量的提高主要通过增加亩穗数和穗粒数实现的;当用量相同时,F2增产效果好于F1。
The effects of “F1” and “F2” on the soil physical properties of two liquid film test samples developed by Fushun and the application effect in winter wheat were studied by laboratory simulation and field experiment. The results showed that the liquid film could increase water stable aggregate and soil stability entropy (QS), reduce soil bulk density, increase soil porosity, double the saturated hydraulic conductivity, and help the soil to retain water and soil moisture; improve the yield and yield of winter wheat With the increase in the amount of increase, up to 6.5%; increase in yield is mainly achieved by increasing the number of ears and grains per spike; when the same amount, F2 yield better than F1.
