摘 要：
在干旱半干旱雨养农业区,连续8年对丰产沟田5种覆盖技术试验示范表明:丰产沟田的最佳覆盖技术是地膜“全盖垅,半盖沟”和“垅盖膜,沟内盖秸秆”,它们均具有充分集中利用天然降水、最大限度保墒、缓解春旱和提高降水利用率,增强作物抗旱能力等特点。

摘 要：
The tests and demonstrations of 5 kinds of mulching techniques used in bumperharvest furrows were conducted for 8 years in succession in the arid and semiarid rainfedagrecultural zone. The results showed that the best mulching technique for the bumperharvest furrows was to cover the whole ridges and half furrows and to multch ridgeswith plastic sheet and inner furrows with crop stalks. In this way,they are able to collectand use natural rainfall water and to conserve soil moisture to the fullest extent and torelax spring droughts and improve water use efficiency as well as to raise the ability ofcrops to resist droughts.
