| 摘 要： | 目的]研究最适宜油葵获得高产的种植密度和施肥水平.方法]对新疆主栽品种KWS303进行施肥和密度间二因子三水平试验.结果]密度与生产水平密切相关,同时在一定的生产水平范围内,这种相关表现为直线相关,同时土壤分析表明,油葵是需肥量较大的作物,但对各种元素的需求又有差别,在新疆富钾的土壤条件下,尽管需氮磷较少,但却严重影响产量.结论]不同的地力水平、密度和肥料的配比是不相同的,因此在实际的生产中应根据实际需要适当的配置密度和施肥水平.

| Abstract: | 【Objective】To research the most appropriate planting density and fertilization level with which sunflower could reach high yield.【Method】Two factors and three levels test between fertilization and density of Xinjiang cultivar kws303 is carried out.【Result】The result showed that density is closely related with the production levels,while within a certain level of production,the relation performed linear correlation,while the soil analysis showed that sunflower is a kind of,crop which requires large amount of fertilizer,but the need of various elements is different.In K-rich soil conditions in Xinjiang,although the need of nitrogen and phosphorus is less,but it seriously affected the production.【Conclusion】During different fertility levels,the ratio of density and fertilizer is not the same,so in the actual production appropriate density and fertilization level should be arranged according to the actual need. |
