摘要
掌握农田土壤水分的变化规律,对保证农作物产量、提高农作物品质具有重要意义。本文收集了徐州市8个墒情自动监测站2016—2022年的监测资料,分析研究了农田土壤水分变化规律。结果表明,农田土壤水分变化主要分春季水分消耗期、夏季水分补给期、秋末冬季土壤水分平稳期3个阶段;土壤含水量变化规律与年降水量成正相关关系;不同的土壤类型对土壤含水量变化规律也有一定影响。研究结果可为节水灌溉、保墒耕作、抗旱减灾等提供技术参考。
Understanding the variation patterns of soil moisture in farmland is crucial for ensuring crop yields and improving crop quality.This paper collects observational data from eight soil moisture monitoring stations in Xuzhou City from 2016 to 2022,analyzing soil moisture variation patterns in farmland.The results indicate that soil moisture variation follows three main stages:the spring moisture consumption period,the summer moisture replenishment period,and the stable moisture period in late autumn and winter.Soil moisture content is positively correlated with annual rainfall,and different soil types also influence soil moisture variation patterns.These findings provide a technical reference for water-saving irrigation,moisture-retentive tillage,drought resistance,and disaster reduction.
