提高渭北旱塬雨水利用潜力的技术途径分析
- Title:
- The Analysis on Technical Approaches to Raise Rainfall Use Potential in Weibei Dry Plateau
- 摘要:
- 根据东新村资料对渭北旱塬雨水利用现状和潜力进行了分析评价,提出了渭北旱塬提高雨水利用潜力应采取的技术途径.认为提高雨水利用潜力应采取综合技术途径,合理施肥、选用抗旱节水品种、应用化学制剂、雨水汇集用于补充灌溉、增加地面覆盖和深耕等栽培措施在当前提高渭北旱塬雨水利用率和利用效率方面有重要作用.
- Abstract:
- Based on the data from Dongxin station,the situation and potential of rainfall use in Weibei dry plateau were analysed and evaluated.The technical approaches to raise rainfall use potential were presented.Author pointed out the comprehensive technical approach should be adopted to raise the rainfall use potential.In recent,rational chemical fertilizer application,selection of variety with drought resistance and water saving,application of chemical agent,rainfall catchment and limited irrigation,increase of soil surface coverage and deep tillage play an important role in raising rainfall use rate and rainfall use efficiency.
