| 中文摘要: |
| 在民勤地区进行辣椒全膜垄作沟灌与保水剂配合节水技术试验,测定免储水灌注水移栽条件下辣椒地土壤水分扩散规律、辣椒耗水规律及产量效应,分析配套施用保水剂对辣椒地土壤水分的影响。结果表明,在民勤地区,辣椒采用免储水灌全膜垄作沟灌注水移栽技术,并配合使用适当量的保水剂,能使辣椒增产19.73%,节水30.79%,水分利用效率提高42.33%;适当施用保水剂具有减少作物耗水量的作用,保水剂在合理使用范围内施用增产效果明显。 |
| 英文摘要: |
| Through an experiment on water saving technology of pepper under furrow irrigation in ridge culture with
full film-covering combined with water-holding agent in Minqin region during the months of May to Sept. in 2009，the soil moisture diffusion, water consumption and yield effect of pepper were tested under transplanting with water condi-tions. The impacts on soil moisture were analysed in matching application of water-holding agent. The result showed that in Minqin，using technology of transplanting pepper with water under furrow irrigation in ridge culture conditions and matching application of water holding agent would increase pepper production by 19.73%， save water by 30. 79%, and improve water use efficiency by 42.33%. Appropriate use of water holding agent ccould reduce water consumption of crops，and the results were more obvious in using it in the rational range. |
