| 摘 要： | 采用"3414"最优回归设计方法,研究定量施肥对甜菜干物质积累与分配规律的影响。结果表明:同一处理在甜菜生育时期叶片、叶柄和整株干物质积累量呈先增加再减少的规律,而块根干物质积累呈一直增加的趋势;叶片干物质分配比率呈下降趋势,而块根干物质分配比率呈上升趋势。氮、磷、钾肥的配合施用明显促进甜菜块根干物质积累量的增加。不施氮、不施磷和不施钾的3个处理平均块根干物质积累量为110.93g/株,与不施肥处理相比平均增长32.33g/株。氮、磷、钾全施的10个处理平均块根干物质积累量则为134.49g/株,与不施肥处理相比平均增长55.89g/株。 |

| Abstract: | Effect of quantitative fertilization on dry matter accumulation and distribution of sugarbeet was studied with the method of "3414" best regression design.The results showed that the dry matter accumulation quantity of leaf,petiole and the entire plant first increased then decreased while the dry matter accumulation quantity of sugarbeet root increased under the same treatment at the vegetative growth stage.The dry matter distribution ratio of leaf decreased while that of sugarbeet root increased.The coordinated application of nitrogen,phosphorous and potassium significantly promoted the increase of the dry matter accumulation of sugarbeet root.The average sugarbeet root dry matter accumulation quantity of the three treatments with no application of nitrogen,phosphorus and potassium was 110.93g/plant,and it increased by 32.33g/plant compared with no application of any fertilizers.The average sugarbeet root dry matter accumulation quantity of the ten treatments with coordinated application of nitrogen,phosphorus and potassium was 134.49g/plant,and it increases by 55.89g/plant compared with no application of any fertilizers. |
