改良材料对空心村复垦土壤温度和水分的影响
|
摘要
选取7种不同改良材料进行小区试验,分析不同改良材料对土壤温度、贮水量的影响。结果表明:不同改良材料在夏玉米生长季土壤5cm的温度及0～105cm土层土壤贮水量均显著高于对照(P<0.05),生长季的平均土壤温度较对照增加了0.9～1.4℃,平均土壤贮水量较对照增加了10.2～32.9mm,不同改良材料均能够有效增温保墒。通过研究分析得到,在空心村整治中,有机肥和粉煤灰的复合施用可明显改善农田土壤水热状况,是区域空心村整治中适合的改良材料,对提升空心村整治土壤质量有着重要的意义。
Seven different improved materials were selected for plot experiment to analyze the effects of different modified materials on soil temperature and water storage.The results showed that the soil temperature of 5 cm and soil water storage of 0～105 cm were significantly higher than that of the control(P<0.05)in summer maize growing season.The average soil temperature increased by 0.9-1.4 ℃ compared with the control in the growing season,the average soil water storage increased by 10.2-32.9 mm compared with the control,and different modified materials could effectively increase the temperature and ensure the moisture.It's analysed that in the renovation of hollow villages,the combined application of organic fertilizer and fly ash can significantly improve the soil hydrothermal status of farmland,and is the most suitable improvement material in the renovation of regional hollow villages,which is of great significance for improving the quality of soil in hollow villages.
