摘要
研究了膜下滴灌墒情监测点的布设方案,为降低监测成本,提高田间信息采集精度提供了理论指导。在新疆库尔勒市包头湖农场48 m×56 m(一根支管控制)的区域内,制定了3种墒情监测点布设方案,并对方案合理性进行了分析,结果表明,此3种监测点布设方案下插值后计算出的土壤含水率与实测样本土壤含水率,在显著性水平0.05下,没有显著性差异;综合考虑农田规格、合理监测点数目、以及监测点位置等因素,一根支管控制区域内土壤墒情测布设方案可采用30 m×10 m网格。
The design of soil moisture monitoring network for plastic-film mulched drip irrigation system was discussed in this article,which would provide theoretical guideline for reducing monitoring costs and enhancing the accuracy of field monitoring data collection. In Korla Baotou lake farm,Xinjiang,three schemes of soil moisture monitoring point layouts were proposed and analyzed for the area of 48 m × 56 m（ controlled by one branch pipe）.The applicability analysis and the monitoring results of these three schemes indicate that,these plans have no significant differences for soil moisture content with the significance level of 0. 05 between the results from interpolation calculation and the actual detected data of field samples. Considering the specifications of farmland,the reasonable number of monitoring points,as well as the location of monitoring points,the grid size of 30 m × 10 m is recommended for the area controlled by one branch pipe.
