摘要
通过不同试点的标准苗床和假植苗床育苗试验,筛选适宜的氮磷钾比例的烤烟育苗专用肥。试验结果表明,低氮高磷(即8:22:16)和中氮中磷(即10:20:15)育苗专用肥效果好,烟苗成苗期提前,烟苗农艺性状明显改善。
The trials of seedling-raising for flue-cured tobacco were conducted in both of conventional soil bed and heel-in-of plant bed in different counties with an aim to screen special compound fertilizer with suitable ratio of N,P and K. The results showed that the special fertilizers with lower N combined with higher P(namely the N,P and K ratio was 8 : 22:16) and intermediate N combined with intermediate P (namely the N,P and K ratio was 10: 20:15) obtained better effects. Applying the two kinds of special compound fertilizers in flue-cured tobacco seedling stage, the period of raising seedlings of being suitable for transplanting was shortened, and the agronomical characteristics of the seedling was improved obviously.
