几种灌溉方式和施氮量对水稻产量影响的研究述评
Review of Several Irrigation Methods and Nitrogen Rate on Rice Yield
摘要
Abstract
In view of the fact that the conclusion of the impact of different irrigation methods and nitrogen rate on rice yield is incon-sistent, 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 condi-tions, so the reasonable water and nitrogen ratio should be determined by the experiment under different planting conditions.关键词
