Review of Several Irrigation Methods and Nitrogen Rate on Rice Yield

  • Online:2016-07-20 Published:2016-07-20

摘要:

针对不同灌溉方式和施氮量对水稻产量影响研究结论不统一的问题,本文在查阅国内外研究文献的基础上,比较分析了传统淹水灌溉、Y型灌溉和滴灌及施氮量对水稻产量影响的研究成果。结论表明,Y型灌水方式比传统淹灌节水32%以上,滴灌比传统淹灌节水60%以上;水稻产量随着施氮量的增加均有显著提高,但过量施氮反而会使产量降低;不同的种植条件,获得最佳产量的水氮比不同,合理的水氮比应结合种植环境进行试验确定。

Abstract:

In view of the fact that the conclusion of the impact of different irrigation methods and nitrogen rate on rice yield is inconsistent, the authors analyzed the impact of three different methods of irrigation, including traditional flooding irrigation, Y-irrigation and drip irrigation, and nitrogen rate on rice yield in this paper, on the basis of consulting the domestic research literature. The results showed that Y-irrigation saves more than 32% water than traditional flooding irrigation, and drip irrigation saves more than 60% water than traditional flooding irrigation. The yield significantly increases with the increase of nitrogen rate, but it will decreases with too much nitrogen fertilizer. What’s more, water and nitrogen ratio for getting optimal yield will be different in different planting conditions, so the reasonable water and nitrogen ratio should be determined by the experiment under different planting conditions.

Key words: irrigation methods, nitrogen rate, rice, yield
