摘要
用草炭在科尔沁沙地上进行土壤改良田间试验,结果表明,施用有机质含量高、含有丰富的植物所需营养元素的草炭,可以有效地改善沙地土壤理化性质,提高其保水、保肥能力,增加作物产量。这为科尔沁沙地土壤改良开辟了一条新的途径。
In this paper,the test on Keerqin sandy soil improvement was conducted and the results showed that the application of peat with high content of organic matter and rich in plants needed nutrients could effectively improve the physical and chemical properties of sandy soil,enhanced its ability to retain water and nutrients and improved crop yields.Peat application opens up a new way to improve the keerqin sandy soil.
