| 运用3因素5水平二次回归正交试验研究了饲用甜菜FF10000播种深度、施钾量及栽培密度三因素与块根产量的关系。结果表明:在栽培密度及施钾量较低的水平下三因素对产量的影响大小为:播深>密度>施钾量;在密度与施钾量较高的水平下为:播深>施钾量>密度。理论产量在9861kg/666.7m2以上的三因素组合为:播深:3cm;施钾量:20kg/666.7m2;密度:8800株/666.7m2。计算机模拟三因素对产量最优组合为:每667m2播深3～4cm,施钾量20～30kg、密度6000～8000株。 |
| 英文摘要: |
| The influence of main cultivation factors such as seeding depth, potassium application rate and sowing density on fodder beet was studied with quadratic orthoganol regression design method. It was shown that their effect on the yield of fodder beet could be ranked as sowing depth> sowing density >potassium under low level of sowing density and potassium, and sowing depth > potassium> sowing density under high level of sowing density and potassium. The factor composition for a theoretical yield upon 9861 kg/666.7m2 or more was: sowing depth 3 cm, potassium 20 kg/666.7m2, and sowing density 8800 plants/666.7m2.The simulation result showed that the optimal factor composition for high yield of fodder beet was: sowing depth 34 cm, potassium 2030 kg/666.7m2, and sowing density 6 0008 000 (plants/666.7m2.) |
