摘要
测定铜川市耀州区果地、果地-黄姜地和麦地不同类型土壤剖面含水量,研究其0-600 cm之间土壤含水量的变化情况。结果表明,耀州区正常降雨年份果地土层含水量从地表到地下呈现由低到高的变化,200-400 cm范围内出现了发育较弱的轻度干层;果地-黄姜地500 cm以上土壤水分得到了恢复,干层消失;500 cm以下土壤水分得到了补偿,但没有完全恢复。麦地100 cm以下土壤含水量没有明显变化,土层含水量正常。可见,轮作可以使土壤水分在一定范围内得到恢复。最后提出了土壤水分恢复的四点措施。
Based on the determination of soil moisture of the apple field, apple-yellow ginger field and wheat field in Yaozhou of Tongchuan city, the change of soil moisture from 0 to 600 centimeter is studied. The result shows that the change of soil moisture of the apple field is from high to low, and the slight dried layer of soil is obviously formed between 200 and 400 centimeter. The soil moisture of apple--yellow ginger field contrast to the apple field, the soil moisture above 500 centimeter has recovered, dried layer has disappeared. The soil moisture below 500 centimeter has compensated, but not recovered thoroughly. It has not obviously change under the 100 centimeter of wheat field, and it＇s normal. In general, crop rotation is able to make soil moisture be recovered within certain range. At last, four measures have been put forward for recovery of the soil moisture.
