施肥水平对甜菜产糖量的影响

研究了甜菜生产力的适宜施肥水平，结果表明甜菜单位面积产量、产糖量与施肥量间呈二次曲线相关，以Ｎ１０Ｐ１２Ｋ１０（ｋｇ／亩）处理的甜菜产量、产糖量最高，在此施肥量范围内，甜菜产量随施肥产量增加而提高，再增加施肥量进则降低甜菜生产力。

Fertilizer Applied Amount and Sugarbeet Yielding Ability

The thesis studied suitable fertiliser applied amount that effected on beet yielding ability. The results showed that the correlation relationship between fertilizer applied amount and beet yield,sugar yield are curve, the treatment, N10P12K10 (kg/mu) ,has a maxdrium beet yielding ability,within this fertdrier applied amount,beet yielding ability increases with increasing fertilizer applied amount,beyond that will decrease beet yield ability.
