1998-1999年,在山西临汾以裸地条播小麦为对照就黑色液膜覆盖冬小麦的增产效应及机理进行了研究。结果表明:黑色液膜覆盖方式在冬前、拔节期具有较好的生物学效应,促进了小麦的生长发育;在生长中后期有效供给土壤水分,水分生产效率最高,较对照提高28.9%,从而较好地协调了旱地小麦产量三因素,使穗数、穗粒数、千粒重优于对照,亩产达197.7kg。该项研究丰富了我国冬小麦覆盖材料。
In 1998-1999, the yield-increasing effect and mechanism of black liquid film covered winter wheat were studied in bare land in Linfen, Shanxi Province. The results showed that the black liquid film coverage had good biological effects during winter and jointing stages and promoted the growth and development of wheat. The soil moisture was effectively supplied during the middle and late growing period, and the water production efficiency was the highest, 28.9% higher than that of the control Coordinated better three factors of dryland wheat yield, so that the number of spikes, grains per spike, 1000-grain weight is better than the control, per mu reached 197.7kg. This research enriched the winter wheat cover material in our country.
