旱地西瓜节水补灌试验研究

摘要

从水利补灌技术措施出发,进行西瓜不同覆盖栽培方式机械补水的试验研究,分析不同覆盖方式在不同的灌溉制度下对西瓜生长发育、产量的影响,并对西瓜生理生育指标进行了统计分析。结果表明：无色膜草覆盖（少灌2次水）在当地表现突出,表现出节水节能的效果,可提高单位面积的净收益,提高农田水利用效率。%Based on the idea of measures of preserving soil moisture and the supplementary irrigation technology,the watermelon cultivation of different coverages were studie&In this paper,we analyzed the impact of watermelon growth and output under the different coverage ways in supplementary irrigation, the statistical analysis of watermelon physiological indicators had been carried on. The results showed that colorless film-grass coverage had prominent performance in the locate, it could highlight the effectiveness of water-saving and energy conservation, and improve the net income per unit area and agricultural water using efficiency.
