| 中文摘要: |
| 选择延安地区作为黄土丘陵区的代表,在延安地区应用地膜、液态地膜、保水剂、PAM(土壤改良剂)和间作套种措施优化大垄沟种植方式种植玉米,分析了不同优化措施种植玉米的水分利用效率。结果表明,地膜、保水剂、PAM和间作方式有利于大垄沟较好地保持土壤水分,其保水能力分别比平种高出17.4%、8.5%、11.6%、5.3%;液态地膜、地膜、间作和PAM表现出很好的增产效果,其产量分别比平种高出77.7%、72.0%、64.1%、30.8%。 |
| 英文摘要: |
| Based on the broad ridge planting measure,the effects of plastic film,emulsion asphalt,aquasorb,polyacrylamide(PAM) and intercropping on water use efficiency of maize were studied in the loess hilly region in Yan'an.The results showed that the treatments of plastic film,aquasorb,PAM and intercropping could improve soil water effectively,and the water content of these treatment was 17.4%,8.5%,11.6% and 5.3% more than level planting respectively.Moreover,the treatments of emulsion asphalt,plastic film,intercropping and PAM could increase the yield of maize by 77.7%,72.0%,64.1% and 30.8%,respectively. |
