Abstract
The yield-increasing effect about the application of nitrogen fertilizer on sunflower was obvious, the range of yield-increasing was from 28.8% to 51.8% ,the appropriate nitrogen volume was 92-115 kg/hm2. On the nitrogen fertilizing method ,the effect was the most obviously when using one-third of nitrogen total amounts as subsoil and two-thirds of nitrogen total amounts as additional ferlilizer, applied in squaring stage.关键词
