摘要:
为了弄清不同灌溉方式对日光温室番茄水分利用效率及硝态氮在土壤剖面中迁移的影响，选择山东寿光日光温室，以当地主栽品种“齐达利”为试材，研究了沟灌、小水勤灌和滴灌3种灌溉条件下设施番茄的产量，水分利用效率及硝态氮在0-90 cm土壤剖面中的分配规律。结果表明，与传统沟灌相比，小水勤灌、滴灌均能够显著提高设施番茄经济产量，增产率分别为15.5%，11.3%，同时节水率分别为16.7%，36.0%，而相应产量水分效率则分别提高了38.7%，74.0%；同时，两种灌溉方式还显著改变了硝态氮在土壤剖面的分布，将更多的硝态氮保留在作物所能再利用的土层中，减少了硝态氮的淋失，对保护地下水环境具有重要意义。
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 irrigation 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 74.0% 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.
