【摘要】：為了解定邊縣新增耕地的土壤鹽漬化現(xiàn)狀,對陜西省定邊縣鹽漬化土壤面積較大的堆子梁鎮(zhèn)新增耕地典型地塊進(jìn)行田間采樣調(diào)查,并對采集的土樣和水樣及時分析測試。結(jié)果表明:定邊縣堆子梁鎮(zhèn)王灘子村、小灘子村、白土崗子村的新增耕地調(diào)查地塊內(nèi)0~60cm土層的pH均呈強(qiáng)堿性(pH≥9),土壤全鹽量較高;其中,白土崗子村調(diào)查地塊的0~60cm土層全鹽量最重,小灘子村次之,王灘子村最輕。3個調(diào)查地塊蓄水溝內(nèi)水樣均呈堿性,全鹽量322~1 462mg·L~(-1)。根據(jù)調(diào)查區(qū)域的新增耕地鹽漬化現(xiàn)狀,參考當(dāng)?shù)丶班徑貐^(qū)較成功的鹽漬土改良經(jīng)驗(yàn),針對性的總結(jié)了耕作措施、地表覆蓋措施、隔鹽措施、化學(xué)措施、灌溉措施、植物措施等改良措施的原理及優(yōu)缺點(diǎn),以便為治理定邊縣鹽漬化新增耕地提供技術(shù)參考。
[Abstract]:In order to understand the present situation of soil salinization of new cultivated land in Dingbian County, a field sampling investigation was carried out on the typical plot of newly added cultivated land in Duiziliang Town, Shaanxi Province, where the salinized soil area was large, and the collected soil samples and water samples were analyzed and tested in time. The results show that the new cultivated land in Duiziliang Town, Dingbian County, Xiaotan Zi Village and Baitugang Village all have strong alkaline pH 鈮，
