不同灌溉方式对设施番茄土壤剖面硝态氮分布及灌溉水分效率的影响
Effects of Different Irrigation Methods on Nitrate Nitrogen Distribution in Soil Profile and Irrigation Water Use Efficiency of Tomato in Greenhouse
摘要
Abstract
In order to reveal the effects of different irrigation methods on water use efficiency （WUE） and nitrate nitrogen distribution in soil profile, the experiments were conducted in the solar greenhouse in Shouguang County of Shandong Province, and a local majorly-cultivated tomato variety Qidali was chosen as experimental material. Tomato yields, WUE, and nitrate nitrogen distribution in different soil layers （0 90 cm） were inverstigated with three irrigation methods including little and frequent furrow irrigation, drip irri- gation and furrow （conventional） irrigation. The results showed that under the condition of drip irrigation and little and frequent furrow irrigation, compared to furrow （conventional） irrigation, irrigation water-saving rate were up to 36.0% and 16.7%, tomato yield increased by 11.3% and 15.5%, and WUE increased by 7/1.0% and 38.7%, respectively. The first two irrigation regimes in comparison with furrow irrigation also changed the nitrate nitrogen distribution in the soil profile, which led to more nitrate nitrogen reservation in the soil layers for crop reuse, and that reduced the risk of nitrate nitrogen leaching, and comsequenly it was of greatly importance to protect local groundwater environment.关键词
